随着煤层气井开发的不断深入,修井作业过程中井况越来越复杂。近两年油管砂卡问题出现的频率大幅增加,严重制约煤层气井的正常排采。本文立足近两年研究区块修井中油管砂卡实际情况,借鉴其他油田处理油管砂卡经验,总结并优化出几种行之有效的处理方案,以期实现煤层气井的连续、高效和低成本开发的目的。
With the continuous development of coalbed methane wells, well conditions are becoming more and more complicated during workover operations. In the past two years, the frequency of tubing sanding problems has increased dramatically, seriously restricting the normal drainage of CBM wells. Based on the actual situation of tubing sanding card in workover wells in recent two years, this paper draws lessons from the experience of other oilfield sanding pipe sanding cards and summarizes and optimizes several effective treatment schemes to realize the continuous, efficient and low cost development of CBM wells the goal of.
