摘要
多分支井是增加煤层气井产量及降低开采成本的有效途径。本文通过对大城煤层气储层特征的分析和研究,指出了大城区煤层气的赋存环境适用多分支井技术进行勘探开发,并根据钻井揭露的煤层厚度的实际情况,提出了井身结构可能存在的两种设计模型,并对测试井相关的技术参数进行了研究。
Multi-branch wells can effectively increase CBM production of unit well and decrease development cost. Analysis and study on eharacteristies of Dacheng CBM reservoirs have proved that multi-branch well technology is a better choice to develop the reservoirs according to its geological eonditions. Two models are recommended that might be used to design well structures based on seam thickness. Study on relevant technical parameters of test wells is also made in the paper.
