摘要:
 

页岩气井水平段长、压裂井段多、入井砂液量大，钢丝作业过程中工具串遇阻事件时有发生。在优选入井工具

串的基础上，优化工作制度，建立了相应的防治体系，包括合理的下入深度，注入乙二醇、热水与蒸汽等手段，形成了一套钢丝作业在页岩气井中遇阻原因判别方法与解堵措

施。经对13口井井口遇阻及18口井井筒遇阻现象分析，准确判断出遇阻原因，并成功解除堵塞。提出的原因分析及对应的防治措施可有效解决钢丝作业遇阻问题，为钢丝作业

在页岩气开发中的应用提供技术支持。

Abstract:
 

A shale gas well has a long horizontal section which is fractured in many stages

with a large amount of sandcarrying fracturing fluid, so that stuck tools often appear during wireline operation. On the basis of optimizing the

tool string, the working system was optimized, and the corresponding measures were taken, such as a reasonable running depth, injecting ethylene glycol,

hot water and steam, and finally an effective system for analyzing stuck causes and taking measures was developed for wireline operations in shale gas

wells. The stuck causes at the wellheads of 13 wells and in the wellbore of 18 wells have been found, and the blockages were successfully removed.

The causes found and the measures taken can effectively improve wireline operation. The system provides technical support for wireline operation in

the development of shale gas.
