In order to promote green development, Dagang Oilfield has gradually promoted the application of a new surface system model.

As of October 31, 1,750 Wells had been drilled and 997 Wells had been put into operation in the production capacity construction of the self-operating area of Changqing Gas field, with the gas contribution of new Wells reaching 1.15 billion cubic meters, and the quality and efficiency of gas field development had been improved, ensuring the long-term energy storage of natural gas

On September 19, the oil production plant No. 3 of Huabei Oilfield, which had been shut down for more than 4 years due to high water cut, opened the well with ultra-short radius horizontal well technology, and the daily oil production reached 11 tons, which has been stable for 48 consecutive days. In Huabei Oilfield, ultra-short radius horizontal well technology is used to excavat

Reed ponds, rice fields, oil Wells criss-cross, Liaohe Oilfield Huanxiling oil production plant is located in the "wetland capital" reputation of Panjin. In the past six years, Liaohe Oilfield has actively organized the withdrawal of more than 900 square kilometers of protected areas, and invested a lot of funds to complete the shutdown and withdrawal of equipment and facilities

On May 21, Tarim Oilfield made full use of the natural advantages of the southern Xinjiang region located in the first and second solar radiation areas to strengthen the construction and operation and maintenance of new energy projects such as photovoltaic. At present, the photovoltaic power stations maintain the best state of full capacity grid-connected power generation, and th

On May 14, Well Xinghua 1 Ping 5 in Bayan Oilfield of North China Oilfield was successfully drilled with a drilling depth of 6017 meters, a horizontal section length of 1032 meters, and a drilling cycle of 55.5 days, which broke the record of the deepest horizontal well and the shortest drilling cycle in the kilometer horizontal section of Bayan Oilfield and became the deepest hor

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.
