织金工区煤层气水平井压裂砂堵分析与应对措施
|
摘要
水平井分段加砂压裂是目前煤层气开发的一种重要方式。结合织金工区压裂施工实例,对煤层气井施工出现砂堵的原因进行剖析,提出了针对性的处理措施,提高了施工成功率,达到降本增效的目的,为织金工区煤层气井开发提供技术保障。
Sublevel fracturing with sand of horizontal wells is an important method for the development of CBM.Combined with the fracturing construction examples in Zhijin district,we analyzed the reasons of the sand plug in fracturing and proposed the corresponding measures,thereby,to improve the success rate of the construction and achieve the purpose of reducing the cost and increasing the efficiency.It provided technical guarantee for the development of CBM wells in Zhijin area.
