针对煤层气特点以及开发过程中压裂工艺技术存在的问题,研究了一项以套管注入、高排量、活性水携砂为主的煤层气清水压裂配套工艺技术。该技术在山西沁水盆地SH煤田现场应用实践了6口井,并获得成功,压后正处于排水阶段,出气效果明显。
According to the CBM(coal bed methane) features and possible difficulties in fracturing techniques, a new hydraulic fracturing method with casing injection, high output and activated water carrying sand was developed. It showed great effect in the Qinshui coal field.
