Sinopec News Network News To build a solid foundation for stable production in 2022, the Henan Oilfield Development System launched a production capacity construction plan deployment battle at the end of April.
It will complete the deployment of 50 new wells on the basis of completing the deployment of new wells in 2021 in May
.
The development system is planned and studied in advance, the target is selected to fight the "annihilation war", and the actuarial benefit account will be deployed.
By the end of May, 76 new wells will be deployed to overfulfill the battle mission
.
In the first seven months, 122 new wells were deployed in the oilfield, with a designed annual production capacity of 137,000 tons, respectively completing 200% and 210% of the plan at the beginning of the year
After many rounds of adjustments in the old area, the distribution of remaining oil has become more and more complex, and the deployment space for new wells is getting smaller and smaller.
It is almost impossible to deploy 50 new wells at the conventional research speed
.
The development system has repeatedly discussed and determined the work policy of "reservoir clustering, problem orientation, targeting potential, concentration of forces, and fighting annihilation", and decided to select a more mature production capacity construction plan, concentrating superior forces to fight the "annihilation" to ensure the success rate
.
The updip area in the northwest of the 8th and 9th oil groups of the Shuanghe Oilfield is a target block of the "War of Annihilation"
.
This block is in the late stage of ultra-high water cut development, and the injection-production efficiency is poor, and the oil production rate continues to decrease
From the end of April to May, technicians analyzed the potential of different types of oil reservoirs, selected the best from the best and proved the target, successively implemented 8 development plans in the Shuanghe, Gucheng, Wangji and other oil fields, and deployed 76 new wells
.
To ensure the quantity, it is necessary to ensure the quality
.
The technicians have repeatedly compared and demonstrated, and strive to obtain the maximum return with the least investment, so that the previously unprofitable program becomes effective or even high-efficiency
Chun 10 block of Chunguang Oilfield is a medium-deep thin-layer heavy oil reservoir, with high cost of steam injection and serious water channeling
.
Technicians carry out integrated research on reservoir-drilling-oil-production-surface, classify and evaluate and characterize superior reserves of 2.
Among the 76 new wells, technicians have deeply optimized and expanded the cost reduction space, and the number of new wells that can be implemented at a price of US$50/barrel reached 61
.
After the pre-exploration wells and rolling evaluation wells in the Bi446 well block of the Zhaowa Oilfield have obtained high-yield oil flows, the technicians immediately studied the geology, optimized the development plan, and prepared the drilling geological design in advance, so that the development plan and the drilling geological design of the area were edited and reviewed The time has been shortened by 40%.
The deployed Well Zhao 93 and Well Zhao 91-1 produced 34.
7 tons and 21.
8 tons of pure oil per day respectively after they were put into production
.
"We will do a good job in tapping the potential of the old area, reducing wells and high production, and adjusting the well pattern, so as to prepare for the oilfield's production to return to 1.
2 million tons next year
.
" said Long Weijiang, director of the Development Research Institute of Henan Oilfield Research Institute
