摘要：为了解决煤层气开发普遍存在的区城储层变化复杂、不同地区工程技术的适应性差异大等问题，基于治水地高煤阶储层的横向变化特征，分析研完了以往煤层气开发中工程技术的应用效果，结合大量宝内实验及现场实践，提出了一整套以疏导式开发理念为核心的煤层气开发工程技术思路，形成了以可控水平井和疏通式煤层改造工艺为主体的技术系列。现场应用效果良好，可控水平并钻井周期缩短20%~30%，钻井成本降低30%~50%，直井疏通式改造平均单井日产气增加大于500m d，有效提高了煤层气开采效益，为今后煤层气高效开发提供了理论与技术支撑。

Abstract: It is common in the process of coalbed methane (CBM) development that the change of regional reservoirs is complex and the adaptability of engineering is diverse in different areas. To deal with these problems, the application results of engineering which eeeee aeoase the Qinshui Basin. Then, based on abundant laboratory tests and field application, a complete set of CBM development engineering idea with the dredge development concept as the core was proposed. And a series of technologies with the controllable horizontal well and the dredge coal reservoir stimulation technology as the main parts were developed. The test results of field application are remarkable and CBM exploitation benefit is improved effectively. The drilling period of controllable horizontal wells drops by 20%-30%, the drilling Ss ed e e e ae ae d ses e % by over 500 m'/d. The research results provide the technical support for the high-efficiency CBM development in the future.
