摘要
应用多分支水平井钻井技术开发煤层气,是提高单井产量、降低综合成本的有效手段。结合山西煤层气多分支水平井钻井实践,介绍了其工艺特点、应用技术及存在的问题。研究结果表明,应用多分支水平井钻井技术进行煤层气开发,可提高气井单井的综合收益。
Applying the drilling technology of multiple branching horizontal to the exploration of coal-bed gas is one effective means to increase the output of the single well and reduce the comprehensive cost.Combined with the drilling practice of multiple branching horizontal well for coal-bed gas in Shanxi,an introduction is given to its technological characteristics,applied technology and existing problems.It is shown that exploring the coal-bed gas by applying multiple branching horizontal well technologies can increase the comprehensive benefits of the single gas well.
