China’s largest oil and gas field produces over 1 billion tons of oil and gas
On September 3, the reporter learned from PetroChina that the cumulative oil and gas equivalent production of China’s largest oil and gas field, PetroChina Changqing Oilfield, exceeded 1 billion tons, injecting strong momentum into ensuring national oil and gas energy security and promoting coordinated regional economic development.
In eastern Gansu, at the development and construction site of the Longdong Oilfield of Changqing Oilfield, a high-yield oil well was successfully put into production recently, with a daily oil output of 3.6 tons. Since the beginning of this year, Changqing Oilfield has completed the drilling of 435 shale oil wells and newly put into production 797 natural gas wells.
Located in the Ordos Basin, more than 95% of the reservoirs of Changqing Oilfield belong to world-class low-permeability oil and gas reservoirs. The so-called low permeability means that the oil and gas have very poor underground seepage ability. Relying on scientific and technological innovation, Changqing Oilfield has overcome a series of world-class exploration and development problems of low-permeability oil and gas fields, and built a “marginal oil field with no economic exploitation value” into the largest oil and gas field with the highest annual output in my country.
At present, Changqing Oilfield has achieved a high and stable production of more than 50 million tons for 11 consecutive years, continuously breaking the production record of oil and gas fields in my country. At present, the annual oil and gas production of Changqing Oilfield accounts for about 1/6 of the domestic production.
