摘要
苏里格气田三低气藏气井普遍无自然产能,需要采取储层改造措施。目前,主要采用水力压裂,其是一种成熟、有效、经济的储层改造措施。水力压裂气井在压后排液、天然气生产过程中存在支撑剂回流情况。通过生产实践,阐述了支撑剂回流造成的危害,分析了支撑剂回流的基本原因,提出了防治支撑剂回流的基本对策。
The gas wells in the third low gas reservoir of Sulige gas field generally have no natural productivity, so reservoir reconstruction measures need to be taken. At present, hydraulic fracturing is mainly used, which is a mature, effective and economic reservoir reconstruction measures. Reflux of proppant exists in hydraulic fracturing gas wells during the production of fracturing fluid and natural gas. Through the production practice, the harm caused by proppant reflux is expounded, the basic causes of proppant reflux are analyzed, and the basic countermeasures of prevention and control of proppant reflux are proposed.
