煤层压裂工艺技术研究及应用

Research and Application on Fracturing Technology of the Coalbed-Gas

目的：对煤层压裂施工技术进行总结。方法：根据煤层物性的基本特点，确定合理压裂施工参数并选用合适的压裂液体系进行施工。结果：对14口煤层气井进行了压裂施工改造，成功率100％；获得了良好的经济效益。结论：针对现场情况选定的压液液体系可以满足施工要求，并可进行推广使用。

According to feature of coalbed-gas reservoir and fracturing theory of oil-gas well, We made research and application on fracturing design, fracturing fluid, propping agent and fracturing monitoring act in the coalbed-gas well. We obtained a set of fracturing technology of the coalbed-gas and better effect by applying in fourteen wells (thirty beds) in five areas. It had good economical and social benefits.
