China Petroleum Network News as of December 14, the multi-stage gas lift valve coiled tubing gas lift technology independently developed by the Tuha Gas Lift Technology Center has been operating stably for 200 days in the Shengbei 506H well of the Tuha Oilfield, marking the world's first multi-stage gas lift Valve lift coiled tubing gas lift well test was successful.
Shengbei 506H well is 4,980 meters deep. In April this year, a 3,500-meter multi-stage gas lift valve coiled tubing gas lift string was run. After gas lift, self-injection production resumed, with a liquid production volume of 24 cubic meters per day. In early October, Shengbei Well 506H switched to continuous gas lift production just before the blowout was about to stop. It has been in production for more than 60 days, with a daily gas production of 8,900 cubic meters and a daily oil production of 1.8 tons.
Gas lift oil production technology is an oil production method that injects high-pressure gas into the production string to lift crude oil to the surface. Tuha Gas Lift is a brand technology of PetroChina, which currently serves nearly 2,000 wells around the world. Multi-stage gas lift valve coiled tubing gas lift technology is the key technology used by Tuha Gas Lift Technology Center to overcome the "stuck neck" problem of gas lift production in deep wells and ultra-deep wells in my country. By combining coiled tubing technology with gas lift technology, it has unique It has the advantages of moving pipe string, simple and reliable construction process, and greatly reducing the ground gas injection pressure. In the next step, this technology will be tested and applied in multiple wells in the Tarim Oilfield.
