BEIJING, Aug. 25 (Xinhua Du Yanfei) — The reporter learned from PetroChina today that PetroChina’s Daqing Oilfield Gulong Shale oil exploration has made a breakthrough, with an oil-bearing area of 1,413 square kilometers implemented this year and new oil forecast geological reserves of 1.268 billion tons, and has passed the review.
According to the person in charge of the Daqing oilfield, the Daqing oilfield was deployed to drill the ancient page oil flat 1, Ying page 1H, ancient page 2HC, and other key exploratory wells harvesting daily oil production of more than 30 cubic meters of high production and stable trial production, including the ancient page oil flat 1 well to see oil production for more than 500 days, cumulative production of more than 6,000 tons of crude oil, cumulative production of oil and gas equivalent of nearly 10,000 tons. At present, 43 straight wells have produced oil on the plane, and 5 horizontal wells have been highly productive.
Daqing oilfield exploration and development has been more than 60 years, in the face of the oilfield storage and production imbalance and the challenge of stable production, Daqing oil innovative, unconventional exploration ideas, strengthen the study of shale oil enrichment law and enrichment layer evaluation and horizontal well fracturing to improve production and achieved a series of progress in shale oil in situ reservoir theory, key engineering technology, exploration practice.
According to the introduction, Daqing oilfield will start drilling 100 wells this year; 58 wells have been completed, 27 wells have been tested, 25 wells have seen oil, 17 wells have been industrial oil flow. At present, according to the new model of “project management, market operation, platform deployment, factory operation, intelligent control, and low carbon development,” the development pilot test is being carried out, and the construction of the national demonstration area of Daqing Gulong onshore shale oil is actively promoted. “During the 14th Five-Year Plan period, Gulong shale oil will add 1 billion tons of proven geological reserves, and the annual production of shale oil will reach more than 1 million tons.
