摘要
采用可钻式插管挤灰桥塞能提高封堵质量,但这种工具挤灰作业后,钻磨桥塞工作量较大,占井周期长,作业费用高,影响开井时率。研制的可取式插管挤灰桥塞(简称可取式挤灰桥塞),经现场应用表明,该工具具有施工简单、安全方便、成本低等特点,经济效益显著。
During the operation of squeezing cement, drillable bridge plug of squeezing cement can enhance the plugging quality. However, after squeezing cement, the workload of drilling and milling bridge plug is quite great, the well-occupying time is long, the operation cost is high,conducing that the time rate of well production is affected. To solve these problems, we have developed retrievable bridge plug successfully. This paper gives the development and application of the retrievable bridge plug of cement squeeze.
