Xi'an, 10 Oct (ZXS) -- PetroChina Changqing Oilfield revealed on 12 October that as of October 12, Changqing Oilfield's natural gas output this year reached 10.11 billion cubic meters, exceeding 400 billion cubic meters for five consecutive years, 93 days ahead of the same period last year.

According to reports, in 2010, the natural gas output of Changqing Oilfield exceeded 200 billion cubic meters, ranking the largest gas producing area in China. Since then, Changqing Oilfield has successively exceeded the output nodes of 300 billion cubic meters, 400 billion cubic meters and 500 billion cubic meters, and built China's first large-scale gas production area with an annual output of 500 billion cubic meters.

The Ordos Basin, where Changqing Oilfield is located, is a typical "three low" oil and gas field in the world, and economic and effective development is a worldwide problem. Changqing Oilfield has innovatively formed 6 main technologies for tight gas development in six categories, including three-dimensional earthquake, horizontal well excellent fast drilling and volume fracturing, and efficiently built China's first 30 billion cubic meter tight gas horizontal well overall development demonstration zone, creating an innovative highland for unconventional natural gas development.

After the end of the heating in the spring this year, Changqing Oilfield immediately compiled a new round of winter supply guarantee work manual, and conducted dragnet "physical examinations" on 19 natural gas purification and processing plants, 300 gas gathering stations, and more than 3,2 kilometers of gas pipeline networks to ensure that more than 11,1080 gas wells were in the best condition to meet peak supply guarantees. In order to improve the natural gas supply capacity in extreme weather, Changqing Oilfield accelerated the construction of gas storage reservoir groups, organized gas storage injection and production rotation ahead of time, and this round of gas injection has exceeded 1.24 billion cubic meters, and the daily peak shaving capacity can reach <>.<> million cubic meters. At present, the daily gas output of Changqing Oilfield is running above <> million cubic meters, which is fully prepared for a new round of winter supply.

It is reported that Changqing Oilfield has successively developed 14 gas fields such as Jingbian, Yulin, Sulige and Qingshiyan, with a cumulative production of more than 6000 billion cubic meters of natural gas. (End)
