The cost of downhole operations at the northwestern Yakla fine-drilling site was reduced by 3.86 million yuan

Sinopec News Network reported on June 8, at the YK13 well transfer operation site of the Northwest Oilfield Yakela Gas Plant, the roar of the workover rig resounded through the Gobi Desert.
The downhole operation team technician of the Development Research Institute Sun Bolin and the construction unit were working Optimize the workover process to save the operation cycle and reduce the cost
.

In 2021, the Yakela Gas Production Plant will implement the integration model of geology and engineering, earnestly implement the main responsibility of reservoir operation and management, subtract the operation process, clarify the family status and add, and relocate the operation as the division, highlight the concept of geological and engineering integration, and go through the fine process.
Management and control, evaluation and optimization measures ensure the seamless connection of each process, which guarantees both the quality and benefit of downhole operations
.

From January to May, the gas production plant reduced the cost of downhole operations by RMB 3,861,800

The operation process is subtracted, and every penny is spent on the blade

On April 17, at the YK6H well site, technicians used non-rotating wall scrapers to complete the drilling and wall scraping operations in one trip with shoe grinding, achieving the perfect integration of the two processes of drilling and scraping.
Integration
.

This year, this technology has been applied in YK6H and other wells 3 well times, effectively saving 6 days of construction period and saving 198,000 yuan in costs

The Yakla Gas Production Plant uses process innovation as a means to optimize the construction process
.

In workover operations, the technicians used the integrated injection-production combined completion technology, combined with light oil replacement injection technology, to effectively reduce the leakage of the remaining oil in the old formation and the medium-pressure well fluid, reduce the pollution to the reservoir, and reduce The gas lift induces injection time and ensures the safety of well control

On the basis of the in-depth integration of "geological engineering integration", the gas production plant optimized the completion process and adopted the integrated completion technology of injection and production to reduce the operation cycle and improve the operation efficiency
.

This year, it has been applied 4 well times in YK35, YK17, YK31, YK6H and other wells, saving 264,000 yuan in cost

At the same time, the gas production plant combined with the operation capabilities of the workover team separator and supporting equipment, boldly applied the integrated workover and oil test technology, and effectively reduced the workover team equipment and the oil test team through the workover team equipment in conjunction with gas lift operations.
The installation and dismantling process time has greatly reduced operating costs and effectively increased the speed of commissioning.
On average, a single well was commissioned 8 days in advance
.

From January to May, the YK17, YK31, and YK6H wells were used for 3 well times, which saved 460,000 yuan in single well and realized a cumulative cost reduction of 1.

　　Sorting out the family background and making additions, it is a hard leverage to be able to repair or not to change

　　On March 2nd, during the operation of YK31 well, the technicians repeatedly cleaned and checked the 13Cr tubing that was taken out.
They found that there were 510 tubings in the original well that met the requirements for entering the well.
Only 40 tubings need to be supplemented and repaired, effectively saving 51.
Ten thousand yuan
.

　　13Cr tubing is a special type of tubing that is resistant to carbon dioxide corrosion
.

The Yakla Gas Production Plant is analyzing the application of different materials of tubing and safety valves over the years, combining with the inventory data of repairing old and reclaiming waste, taking the initiative, and optimizing the selection and use of pipes through the strong combination of geological processes to achieve re-optimization of resources, thereby To achieve the purpose of reducing costs and increasing efficiency

　　During the completion of the YK35 well, the technicians made full use of the qualified anti-corrosion tubing from the new well YD1-4H well, reducing the need to repair 352 carbon dioxide-resistant special buckle tubing, saving 352,000 yuan and accumulatively saving 862,000 yuan of tubing costs
.

　　In view of the situation that the gas well in the Yakela block needs to be lowered into the downhole safety valve when it is completed, Party A and Party B have jointly tackled the key problem.
By repairing and maintaining the old safety valve, after passing the pressure test, it is recycled and reused, effectively saving tool costs
.

In 2021, the YK31 well will be used to repair the safety valve, saving 285,000 yuan in costs

　　Divide the homework relocation, save a penny and add a penny

　　On May 9, the operation and construction team of Bazhou Deshi Minor Maintenance Team 3 went to the Bashto oil area eagerly to carry out pump repair work for wells M4 and BK9
.

　　"I did double the work and only ran one trip
.

" Yu Jian, a technician, settled his account.

　　The Bashto block is more than 700 kilometers away from the factory, and the cost of a single operation for each well is as high as 157,400 yuan
.
In response to the problem of high relocation costs in remote areas of Bashto, the gas production plant is not dependent, optimized by multiple parties, and operates efficiently.
It divides the operation and relocation and adheres to the "early planning, early arrangement, batch operation, and centralized relocation".
Management mode, optimize the operation and construction of wells in the same area, make operation plans in advance, and arrange adjacent oil wells to the same construction time period, which not only saves relocation time, but also improves the oil well time rate and realizes the quality improvement of oil well operation and construction , Speed, efficiency, and production
.

　　The gas production plant has improved the efficiency of remote relocation by effectively saving remote relocation costs, and has achieved further reductions in relocation costs
.
In 2021, two batches of remote relocation of remote blocks will be implemented, 4 well-time operations will be performed, and two remote relocation fees will be saved, with a total cost savings of 314,800 yuan and an increase of 8 tons of oil per day
