More Than 100 Drilling RIGS in Tarim Oilfield Have Accelerated Their Advance to Deep Depths
Tarim Oilfield accelerated the introduction of ultra-deep drilling RIGS from 7000 meters to 9000 meters deep Wells, and implemented 19 new drilling RIGS. As of September 18, 12 new drilling RIGS have been in place this year and officially "started" drilling. By optimizing and adjusting drilling rig operation, Tarim Oilfield has made every effort to promote deep oil and gas development, and oil and gas production has continued to rise, which is better than the planned operation.
Tarim Oilfield continues to accelerate the pace of advancing deeper, and a number of deep and ultra-deep Wells have been deployed in rich oil and gas blocks such as Fuman Oilfield and Boz-Dabei, and the deployment scale and the number of new Wells drilled have increased significantly compared with the same period in previous years. In the face of the current shortage of deep and ultra-deep drilling rig resources, Tarim Oilfield speeds up the pace of introduction, coordinates the deployment and supplement of drilling companies, and establishes a daily tracking and weekly supervision mechanism for the introduction of drilling RIGS, and closely aligns the progress of the introduction of drilling RIGS with drilling companies. At the same time, special personnel were selected to communicate and coordinate with the rig manufacturers and supervise the production in the plant, accelerate the production schedule of the rig, and make every effort to solve the problem of the rig gap. According to the overall annual drilling plan, the plan will also introduce new drilling RIGS in the future, go all out to ensure the drilling of deep and ultra-deep Wells in the oil field, and accelerate the process of ultra-deep oil and gas exploration and development.
At the same time of accelerating the pace of the introduction of drilling RIGS, the Tarim oilfield maximizes the potential of in-use drilling RIGS, inverts the drilling processes according to the deployment of well locations, promotes the strategy of "relay running" of large and small drilling RIGS, allows large drilling RIGS to "open the road" and small drilling RIGS to take over, and gives priority to ensuring the drilling of key Wells. After the large drilling rig completes the maximum load drilling construction, deploy a small drilling rig with suitable performance to complete the subsequent well section construction, shorten the occupation period of the large drilling rig, maximize the activation of the existing drilling rig resources, ensure that the rig and the backup well location form a good matching relationship, and realize the rig and the well section "can match", "full count" stop.
At the same time, Tarim Oilfield has made every effort to promote the speed and efficiency of drilling. He Silong, deputy director of the Engineering technology Department of Tarim Oilfield, said: "Recently, we convened 17 units such as scientific research, production, drilling and technical service companies to carry out drilling speed exchange meetings, collect suggestions and gather wisdom to solve key problems, and form 42 drilling speed improvement measures in six categories, supporting the overall drilling rig operation efficiency of the oilfield to increase to 98%, a record high." At present, Tarim Oilfield is drilling an ultra-deep well of 8,000 meters in Fuman Oilfield, and the drilling cycle has been shortened from more than 300 days in the past to the current average time of about 150 days, the fastest drilling within 100 days, greatly accelerating the pace of deep oil and gas exploration and development.
At present, there are 130 drilling RIGS roaring in the desert Gobi in Tarim Oilfield, speeding up the advance to deep and ultra-deep underground, of which 50 Wells are better than the design cycle, and strive to put new Wells into production and contribute early. While the fault complex time decreased, the production time of Tarim oilfield not only increased by 0.37 percentage points, but also increased by 1.08 m/h and 137.3 m/unit, respectively.
