煤层气井作业地质施工设计优化研究

On optimal design for geological construction of coal-bed gas well

介绍了煤层气井下作业故障的原因,分析了沁水地区泵故障、煤层吐砂、抽油杆断脱三种井下作业故障的周期与影响因素,并探讨了对应的解决方法,旨在延长煤层气井作业周期。

The paper introduces the reasons for the default at the construction of the coal-bed gas well, analyzes the cycle for the default and in-fluential factors from the pump default in Qinshui Area, sand from coal-bed, and disconnect of sucker rod, and explores the respective solutions, so as to prolong the construction period of the coal-bed gas well.
