The success rate and the emission rate of the wheel are 100%. Jishen 5-8 pla

As of December 25, the first "Fengfeng Firewood storage" microgrid of the second Oil production plant of Changqing Oilfield has been put into operation for 1 month in the Mu 165 well site of Fanjiachuan operating area, and all indicators are normal. The project is the first zero-carbon well site successfully built in Changqing Oilfield and is expected to save 10.4 tons of diesel

The picture shows Hei125 gas injection platform well in Jilin oilfield. Jilin Oilfield is committed to low-carbon development and green transformation, and has realized "carbon" into gold. As of March 5, in the 15 years of Changling gas field development, Jilin oilfield has injected 2.91 million tons of carbon dioxide, equivalent to planting nearly 26.19 million trees.

In the first two months of this year, the ninth oil production plant of Daqing Oilfield used diversified means to continuously strengthen the potential of the old area, and crude oil production increased by 195,000 tons year-on-year. The geological conditions of oil reservoirs developed by No. 9 Oil Production Plant are complex and changeable, including medium permeable oil

As the northern Hemisphere enters winter in November, temperatures are generally cooler, economic activity weakens and demand falls. The petrochemical industry represents the demand side of the fuel processing industry and rubber, plastics and other polymer products manufacturing industry boom index growth rate fell significantly. Chemical raw materials and chemical products manu

First, the function of the ball valve balance hole The balance hole is also called the compensation hole, which refers to a channel inside the ball valve, generally located between the two sealing surfaces above and below the ball. Its role is to balance the pressure on both sides when adjusting the pressure outside the section to ensure the normal operation of the valve. T

Recently, the first 175 mpa ultra-high pressure maintenance test center of Northwest Oilfield was completed and put into use in Xinjiang Laisu Industrial Park. Covering an area of about 23,000 square meters, the center has more than 40 sets of advanced industrial equipment such as 280 mpa watertight and airtight pressure test tables, and more than 50 kinds of oil field mat

On November 2nd, China's independently developed first 270000 cubic meters of liquefied natural gas storage tank was put into operation in Qingdao, which is also the largest liquefied natural gas storage tank in China. Its operation has greatly improved the natural gas supply guarantee capacity in North China. The first 270000 cubic meter liquefied natural gas stor

In early October, the Dalaoba gas storage in Northwest Oilfield transitioned from the summer gas injection stage to the winter gas production and supply guarantee stage, with an annual working gas volume of up to 200 million cubic meters, effectively ensuring winter natural gas supply. Since last year, in response to the rapid growth of natural gas production in

Sealing surface is the most critical working face of the valve, the quality of the sealing surface directly affects the service life of the valve, and the material of the sealing surface is an important factor to ensure the quality of the sealing surface. Therefore, the following factors should be considered when selecting valve sealing surface materials: ① Corro

Focusing on the "dual carbon" goal, the recent "three barrels of oil" have orderly promoted the adjustment and optimization of energy consumption structure, continuously making efforts in new energy business, and investing with unique characteristics. PetroChina is accelerating the development of onshore new energy and electric transportation business, Sinopec is investing in hydrog

This year's strong growth in China's steel exports is mainly supported by three major factors: One is the strong competitiveness of Chinese steel products. Although the uncertainty of the world economy has increased this year, the global manufacturing industry is in a contraction range due to the downturn (Global Manufacturing PMI Index), frequent manufacturing trade frictions in
