可取式挤灰桥塞在挤灰作业中的应用与评价

随着油田二次开发阶段的来临,地层剩余油的挖潜成为油田上产稳产的重要措施。因此近年来油田挤封作业工作量呈逐年上升趋势。而现有两大挤封工艺"笼统挤封"和"可钻式桥塞挤封"已不能满足挤封需求。本文提出了可取式挤灰桥塞挤封的技术思路,并阐述了它的技术特点,应用原理以及使用后的效果评价。可取式挤灰桥塞的使用使工序复杂的挤封作业变得容易,有很大的推广价值。

The Appraisal and Application of the Retrievable Bridge Plug of Cement Squeeze

Along with oil field re-development stage oncoming,the excavation of underground remaining oil is becoming a important measure to increase and stabilize Output.So in recent years oilfield squeezing operation workload is increasing year by year.While the existing two squeezing technology general squeeze and drill style bridge plug squeeze already can not meet the need of development of squeezing.This article introduces the retrievable bridge plug of cement squeezing technology thinking,and elaborats its t...
