On August 25, PetroChina held a press conference in Daqing to announce the news of a major strategic breakthrough in the exploration of Gulong shale oil in the Daqing Oilfield
.
According to Daqing Oilfield, the company deployed to drill key exploration wells such as Guye Youping 1, Yingye 1H, and Guye 2HC, with daily oil production of more than 30 cubic meters and stable test production.
Among them, Guye Youping 1 saw overproduction.
At present, 43 vertical wells have produced oil on the plane, and 5 horizontal wells have achieved high production
.
In 2021, Gulong shale oil exploration will confirm an oil-bearing area of 1,413 square kilometers, and increase the predicted oil reserves of 1.
268 billion tons, which will become an important strategic resource for Daqing's century-old oilfield construction
Daqing Oilfield has been exploring and developing for more than 60 years, and it is currently facing severe challenges of imbalance in storage and production and difficulty in stabilizing production
.
According to the Daqing Oilfield, the company broke through the barriers of understanding, cracked the technical bottleneck, bravely broke through the forbidden exploration areas, innovated unconventional exploration ideas, marched into the shale oil of the Qingshankou Formation in the source, strengthened the study of shale oil enrichment rules and enrichment layer evaluation.
In tackling key problems in horizontal well fracturing and increasing production, major innovations in shale oil in-situ accumulation theory, major breakthroughs in key engineering technologies, and major achievements in exploration practice have been achieved
According to the 21st Century Business Herald reporter, Daqing Oilfield is taking Gulong shale oil as an important strategic area, fully implementing the new development concept, and speeding up various tasks
.
In 2021, 100 wells will be drilled in Daqing Oilfield, 58 wells have been drilled, 27 wells have been tested, 25 wells have seen oil, and 17 wells have obtained industrial oil and gas flow
.
At present, according to the new model of "project-based management, market-based operation, platform-based well deployment, factory-based operation, intelligent management and control, and low-carbon development", the development pilot test is being carried out, and the Daqing Gulong continental shale oil national demonstration zone is actively promoted Construction
