Recently, the new liquid polysaccharide gel water blocking agent independently developed by Northwest Oilfield was applied in well TH12133 of Tahe Oilfield, the water cut was reduced from 97% to 41%, and the daily oil production increased significantly. Northwest Oilfield has successfully developed a new type of liquid polysaccharide gel water blocking agent in view of the aggrav

Nitrogen gas is a common protective gas, mainly used in metal welding, cutting, smelting and other industries. Its principle is to use the inert and non-combustible characteristics of nitrogen to prevent oxygen and other gases from entering the gas environment, so as to achieve the purpose of protecting the metal. The principle of nitrogen protection gas can be explained from th

On May 15, at the northern foot of the Fire Mountain, Tuha Oilfield was constructing more than 700 meters of flood prevention levees, diversion DAMS and water crossing roads in the oil area to prevent snowmelt floods during high temperatures from affecting oil and gas production. Tuha Oilfield is located in the eastern part of Xinjiang, the southern slope of the Tianshan Mountain

Recently, it was learned from the Tianjin Branch of CNOOC that with the construction of Kenli 10-2 oilfield Phase I/Kenli 10-1 oilfield A54 well block development project in Tianjin and Qingdao on the 10th, the construction of Kenli 10-2 oilfield of 100 million tons officially entered the development and construction stage. Kenli 10-2 oilfield is located in the southern waters o

Compressed air energy storage power station refers to the energy storage method that uses electric energy for compressed air during the low load period of the grid and releases compressed air to promote turbine power generation during the peak load period of the grid, which is known as "super green charging treasure". The compressed air channel connecting the ground and undergroun

At 3 am on April 1, the last section of Jishen 5-8 Ping 02 well tool string out of the wellhead, marking that the logging C3291 operation team of CPC successfully completed the first round of bridge shooting of 3 horizontal Wells of the Group's first CBM electric drive fracturing platform after 19 days. 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

Valve body blank heat treatment process according to different materials are as follows: 1. Heat treatment of gray cast iron In order to achieve different purposes, gray cast iron can be subjected to different heat treatments after casting. In the production of valve, the heat treatment processes commonly used for gray cast iron valve body and other parts after casting are: the

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.

Causes of ball valve internal leakage 1. Reasons for internal leakage of the valve during the construction period: ① Improper transportation and hoisting causes the overall damage of the valve, resulting in internal leakage of the valve; ② When leaving the factory, the hydraulic pressure is not dried and anti-corrosion treatment of the valve, resulting in corrosion of the seal

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
