过油管射孔工艺由于不用泥浆压井进行射孔作业,因而具有保护油层、缩短试油周期、简化工序、降低成本等优点,在生产上发挥了良好的效果。大港油田今年以来继续推广使用过油管射孔新工艺成果显蒋,1—6月份完成27井次。这样,从79年9月推广过油管射孔工艺以来,共进行了115井次过油管射孔作业。 Pipeline perforation process because the perforation without mud drilling operations, which has the protection of oil reservoirs, shortening the test cycle, simplify the process, reduce costs and other advantages, in production has played a good effect. Dagang Oilfield continue to promote the use of new technology since the beginning of the tubing perfusion was Chiang, 1-6 months completed 27 wells. In this way, a total of 115 well-tapped pipe launches have been conducted since the introduction of the pipe perforation process in September 1979.
