摘要
在煤层压裂过程中 ,结合煤层高滤失性特点 ,成功地实施了前置液降滤失和油套混注大排量、大砂量、阶段加砂等先进的压裂施工工艺 ,使得煤气产量大幅度提高。辽河油田在东北煤气田压裂施工 6口井 11层 。
In the process of coalbed fracture treatments,combining characteristics of high filtration of the coal bed,the advanced technology of fracture treatment of reducing filtration with pad fluid and casing mixed flooding drainage of larger displacement and larger sands filled are actualized successfully.It can improve production of coalbed gas clearly.Facture treatment processes have gotten good effect which have been constructed for 6 wells of 11 beds in Dongbei coal bed gas field of Liaohe oilfield.
