The origin of New Year's Day can be traced back to Zhuanxu, one of the three prehistoric emperors and five emperors. According to legend, Zhuanxu "took the first month of Mengxia as the yuan", which means that the first day of the first lunar month every year must be "New Year's Day" or "Yuanzheng". This legend has a history of more than 5000 years. Subsequently, different dynasties had varying opinions on the specific date of New Year's Day. The Yin Shang Dynasty established the first day of the twelfth lunar month as New Year's Day, the Zhou Dynasty designated the first day of the eleventh lunar month as New Year's Day, and the Qin Dynasty established the first day of the tenth lunar month as New Year's Day. In the first year of the Taichu reign of Emperor Wu of Han (104 BC), the famous historian Sima Qian pioneered the "Taichu calendar", which takes the first day of the first lunar month as New Year's Day. This method returns to the original provisions of the "Xia Xiaozheng" (the earliest surviving calendar in China that records agriculture), and is therefore also known as the "Xia calendar". This regulation spans a long historical time and space and continued until the Xinhai Revolution. Sun Yat sen designated January 1st of the Gregorian calendar as New Year's Day for the first time In 1912, the Provisional Government of the Republic of China was established. Mr. Sun Yat sen established the first day of the first lunar month as the Spring Festival, and the first day of the first lunar month in the Gregorian calendar (Gregorian calendar) as the New Year's Day, also known as the New Year, in order to follow the lunar calendar. In this sense, New Year's Day is a product and symbol of the evolution of modern and contemporary society in China. In September 1949, the first plenary session of the Chinese People's Political Consultative Conference, which was held on the eve of the founding of the People's Republic of China, passed a

As of November 23rd, the largest natural gas storage facility in China, the Hutubi Gas Storage Facility in Xinjiang Oilfield, has been supplying natural gas to the West East Gas Pipeline and cities along the northern Xinjiang region for two consecutive weeks, ensuring stable supply of natural gas to residents and businesses along the route. Recently, there have been frequent rainy and snowy weather in Xinjiang, with temperatures continuing to decrease. Xinjiang Oilfield is guided by the principle of "ensuring people's livelihoods, public utilities, and key areas", scientifically organizing the integrated operation of natural gas supply and demand, and continuously increasing the operation of various links in natural gas production, transportation, and storage. From the vast Gobi to the hinterland of the desert, various units have entered the winter supply guarantee mode in a "full grid" state, fully ensuring the safe and stable supply of natural gas in winter. The Hutubi gas storage facility in Xinjiang Oilfield is currently the largest in service storage capacity and the strongest in peak shaving capacity in China, with a capacity of billions of cubic meters. Since its completion and operation in June 2013, it has exceeded the injection and production targets for 10 consecutive years, playing an important role in ensuring natural gas supply and seasonal peak shaving in Xinjiang and cities along the West East Gas Pipeline Network. Since the beginning of this year, the Hutubi gas storage facility has combined previous winter supply experiences, pre evaluated the gas demand for this winter and next spring, scientifically formulated winter gas

URUMQI -- The photovoltaic power project in the Tarim Oilfield has generated over 105 million kWh of green electricity so far this year, said its operator, China National Petroleum Corporation, on Saturday. The green energy is equivalent to 22,200 tons of standard oil, reducing carbon dioxide emissions by 70,500 tons, and the electricity that can be used by more than 40,000 households for one year, which has effectively guaranteed the soaring power demand in southern Xinjiang. Of the green electricity generated, nearly 20 percent was consumed within the oilfield to reduce the load of the grid, the company added. Located in Northwest China's Xinjiang Uygur autonomous region, Tarim Basin is a major petroliferous basin in China. The company has discovered and developed 32 large and medium-sized oil and gas fields -- with the total output exceeding 470 million tonnes over the past 30-plus years. Taking advantage of the region's rich solar energy resources, the company has been increasing its pace in the construction of photovoltaic power stations in recent years. A new 500,000 kW photovoltaic power station in Yecheng county is expected to be connected to the grid this year.

The three main types of Oil Country Tubular Goods are drill pipe, casing, and tubing. Drill pipe: Drill pipe is heavy, seamless pipe which provides rotation for circulating the drilling fluid. The pipe helps the drilling fluid to be pumped back up the annulus. The annulus of an oil well is the space between the casing and the piping or any immediate space between any casing and tubing surrounding it. The annulus helps in the easy circulation of the fluid in the well. The pipe is subject to axial tension, as high torque is required for rotating the down-hole assembly and drilling the fluid and circulating it. All this creates a large amount of stress on the drill pipe, hence the OCTG pipe should be extremely strong. This drill pipe is used only at the drilling rigs and they are available in different sizes and different qualities. The quality differs based on the grade of strength, weight, and length of the pipe. The OCTG Drill Pipe is sturdy steel pipe which is required to meet the standards of API 5DP and API SPEC 7-1. Casing:

US troops stationed in Syria looted hundreds of metric tons of crude oil in Iraq on Sunday. This was the third time they did so this year. Earlier, the troops had mobilized 73 oil tankers on April 9 and 23 tankers on April 3 to transport their ill-gotten gains. In 2022, the Syrian government said US troops pillaged 66,000 barrels of oil every day, which is about 83 percent of Syria's total oil production. It is anybody's guess why the US went into Iraq, Libya or anywhere in the Middle East and North Africa. That it is openly stealing oil from Syria, however, takes the cake. Since the civil war broke out in Syria in 2011, the US and its allies have been actively intervening to pull down the government there. US warplanes have been bombing Syrian government forces, supplying arms and ammunition to the opposition forces, and pouring scorn at Syrian diplomats in international forums. Even though the civilian strife has largely stabilized, the Syrian government has lost control of many places in the country. The Kurdish forces, and the Islamic State that emerged later, still control places in Syria. This disintegration of Syria gave the US a chance to take advantage of the situation. When it takes oil, it claims it is from oilfields controlled by the opposition forces; but it even takes oil from Syrian territory and claims it is to help the Kurdish forces.

China's State-owned oil majors rallied on Monday as expectations over accelerated reform of State-owned enterprises grew after regulators vowed new measures to bolster the competitiveness of SOEs. On Monday, PetroChina Co Ltd, the listed arm of State-owned energy giant China National Petroleum Corp, jumped 7.17 percent - the biggest gain in about three weeks - to close at 7.62 yuan ($1.08) per share after falling by more than 17 percent from its recent high in early May. The other two State-owned oil majors - China Petroleum & Chemical Corp and CNOOC Ltd - rose 5.34 percent and 2.06 percent on Monday, respectively. The rally among energy heavyweights underpinned a 0.28 percent gain for the Shanghai Composite Index on Monday, which closed at 3221.45 points, whereas other benchmark indexes tracking A shares dropped. Experts said the gains by oil majors may be a sign that investor sentiment of "the valuation system with Chinese characteristics" - which suggests that the valuation of SOEs has the scope to improve - has strengthened following regulators' latest commitments to boost the development of listed SOEs. Wang Jianjun, vice-chairman of the China Securities Regulatory Commission, said over the weekend that the top securities regulator will work with other authorities

Before starting their own businesses, Bie Xinyun and her husband Du Wenhua were both employees of Zhongyuan Oilfield. In the eyes of ordinary families, these days were comfortable enough, but they had higher life goals. In 1999, Bie Xinyun and his wife went out of state-owned enterprises to operate overseas, raised funds to purchase advanced equipment, recruited professional and technical personnel, and established Puyang Dongfanglong Machinery Co., Ltd. With excellent product quality and good market reputation, in just a few years, cooperative customers have spread across major oil fields such as Zhongyuan, Dagang, Jidong, Xinjiang, Shaanxi, etc. In 2012, with an investment of 120 million yuan, the company took the lead in settling in Pudong Industrial Cluster in Puyang City. It only took two years, and its products were exported to more than 30 countries and regions such as the United States, South Korea, Russia, and Venezuela. Bie Xinyun said, "Great credit leads to great development, while small credit leads to small development. Without credit, it is difficult to develop. What our enterprise can develop to today is this honesty and trustworthiness, which can be said to be the lifeline of our enterprise." In February 2012, Dongfanglong Machinery Manufacturing Company responded to the government's call to relocate the Pudong Industrial Cluster, which has greatly affected production. It is difficult to carry out a large amount of production in a short time, and some orders cannot be delivered on time. However, Biexinyun still decided to deliver the products on time. While working hard to complete the installation and commissioning of the equipment after the relocation, she contacted surrounding enterprises to assist in production. Zhu Ximei, General Manager of Henan Central Engine Baolong Pipe Industry Co., Ltd.: Sister Xinyun is a very trustworthy person. Over the years, our products have never been rushed, and

OCTG Casing Pipe The shape of the casing section is round, in large diameter pipes and is inserted into the oil well, fixed with cement to protect other equipment that is mostly made of iron and steel. The oil well must be designed to withstand the force different from the external power, such as crushing, explosion, stress and chemical corruption. API 5CT casing pipe is used to support the oil and gas pipe wall, and to ensure the drilling process and the post-completion wells normal operation. Each well depending on the depth of drilling and geological conditions, to use several layers of casing. After cementing casing to be used to go down, it different from tubing, drill pipe and can not be reused, a one-time consumable materials. Therefore, the casing consumption accounts for over 70% of all the oil well pipe. According by usage can be divided into the sleeve pipe, surface casing, casing and production casing. OCTG Tubing Pipe OCTG Tubing pipe goes inside the casing pipe because it is the pipe through which oil makes its way out. Tubing is the simplest part of OCTG and it is normally found in the segment of 30 ft (9 m), with threaded connection at both ends. The pipe is either used to transport natural gas or crude oil from the producing formation to the facilities where it will be processed after drilling is complete.

In Shanxi, coal-bed methane gets a boost With a new well to extract coal-bed methane in Jincheng, Shanxi province, on Saturday, daily gas production of Petro China Huabei Oilfield Co in the Qinshui Basin exceeded for 5.5 million cubic meters for the first time, according to China National Petroleum Corp. The company has developed the country's largest coal-bed methane field, with an annual output of 2 billion cubic meters. Coal-bed methane is a unique clean energy resource. Development of the industry can help relieve shortages of oil and gas in China while protecting the local environment, the company said. Shanxi's proven reserve of coal-bed methane is 8.31 trillion cubic meters, one-third of the nation's total. Covering an area of more than 3,000 square kilometers, the Qinshui coal-bed methane field in southeastern Shanxi is estimated to have 600 billion cubic meters methane. "In recent years, a series of high-energy horizontal well technologies have been applied in the Huabei Oilfield," said Hu Qiujia, the manager of Shanxi Coal-Bed Methane Co. "So far, a total of 4,600 wells have been drilled and the output co

Wider use of technologies benefits daily operations Shi Wenbin, a 57-year-old oil worker, knows only too well how bitingly cold it can be in Daqing, Heilongjiang province, in winter, when temperatures often plummet to -30 C. Describing a winter patrol of a 3-square-kilometer operational area at a local oilfield, he said: "Amid the freezing cold, I and at least 14 colleagues had to inspect oil wells scattered throughout the patrol area every morning and afternoon. Each time, it took us four hours and we walked more than 10 kilometers a day." Shi, captain of an oil production team at Daqing Oilfield Co, a subsidiary of China National Petroleum Corp, and his team have worked in one of the nation's largest oilfields for years, regardless of weather conditions that include snow, rain and extremely high wind speeds. But now they have an efficient helping hand, thanks to the pioneering use of digital technologies such as drones, 5G, the internet of things, big data and video surveillance in and around the oilfield. "Drones now patrol the operational area four times a day, and we only arrange for about six people to do additional inspection work every three days. The technology has greatly reduced our workload and the risk of injury," Shi said
