煤层气氮气泡沫压裂在美国和加拿大已广泛应用并取得良好的效果,目前也是国内煤层气压裂攻关研究方向之一。本文通过描述氮气泡沫压裂井地质及压裂情况,对比了其与常规水基压裂井排采中的异常,并对异常情况的处理方法进行了探讨。
CBM gas foam fracturing has been widely used in the United States and Canada and achieved good results. It is also one of the research directions of CBM fracturing in China at present. This paper describes the geology and fracturing conditions of nitrogen foam fractured wells and compares their anomalies with the conventional water-based fracturing wells. The methods for dealing with these anomalies are also discussed.
