A few days ago, great good news came from the oil and gas exploration in the west slope of the Shawan Sag in the Junggar Basin. Well Chepai 24, a key pre-exploration well, achieved a high production of 100 tons after fracturing the third section of the Permian Jiamuhe Formation. At present, the 6 mm choke produces 150.5 cubic meters of oil and 16,600 cubic meters of gas per day. The casing pressure is 14.3 MPa, and the pressure production is stable.
It is worth mentioning that the high production of Well Chepai 24 is the first breakthrough in the glutenite of the third member of the Permian Jiamuhe Formation in the Shawan Depression, and is a new breakthrough in a new formation after the Upper Wuerhe Formation of Shatan 1, the Carboniferous Formation of Chepai 1 and the Fengcheng Formation of Shatan 2. It will promote the overall exploration of large stratigraphic oil and gas reservoirs in the Middle and Lower Permian in Shawan-Mahu, and further demonstrate the great potential for exploration of.
In recent years, around Shawan petroleum system, Xinjiang Oilfield Company has deepened geological understanding, highlighted efficient exploration, planned large-scale exploration as a whole, carried out seismic data preparation, old data re-processing and regional overall research, realized the overall improvement of geological understanding, laid a good foundation for breakthroughs in this field, and promoted the deployment and drilling of Chepai 24 well.In the process of field organization and implementation, the drilling and oil testing schemes have been continuously optimized, the construction period and cost have been reduced, and good economic benefits have been achieved.

Junggar Basin is rich in oil and gas resources and has great exploration potential.As the main battlefield of increasing crude oil reserves and production in China,Xinjiang Oilfield Company has earnestly implemented the decision-making and deployment of the Party Group of the Group Company this year,taking the protection of national energy security as its own responsibility,striving to overcome the adverse effects of the epidemic,taking the initiative and taking responsibility bravely,and realizing the"two-handed grasp,two-handed hard,two-correct and two-win"of epidemic prevention and control and production and operation.

Especially since the beginning of the year,facing the severe challenges of epidemic situation and low oil price,the company has insisted on controlling resources unswervingly,insisting on efficient exploration and high-quality development,focusing on finding high-quality and scale-benefi t reserves and reducing the cost of oil and gas discovery,making every effort to fight a good offensive battle for efficient exploration,speeding up the breakthrough process in key areas,and striving to make breakthroughs in key areas.A number of important discoveries and achievements have been made in the fields of shale oil in Mahu depression,multi-strata in Shawan depression and lower slope in the abdomen,and the success rate of exploration has been continuously improved.The new industrial oil and gas flow of 68 wells and 75 layers(3 wells with 100 tons)has laid a solid resource foundation for winning the battle for survival and development under low oil prices.

Next,Xinjiang Oilfield Company will carry out in-depth educational activities on the theme of"fighting against severe winter,changing ideas,taking on the responsibility bravely and stepping up",actively promote special actions to improve quality and efficiency and efficient exploration,highlight benefi t exploration,and continue to deepen concentrated exploration in oil-rich areas,risk exploration in new areas and fine exploration in old oil areas.We will persevere in searching for new oil and gas discoveries,major breakthroughs,and high-quality reserves with economies of scale.The oil field should unify its thinking,strengthen its confidence and go against the trend,and resolutely win the battle of epidemic prevention and control and achieve the defense of benefits.
