摘要
以川西致密低渗气藏为研究对象,通过对压裂液滤失、返排规律研究,支撑剂回流、沉降规律及求产期间支撑剂回流规律研究,提出气井压后测试制度应根据不同阶段进行动态优化的设计思路,给出相关计算公式,以新场气田为例,进行了实例计算。计算结果与实际吻合,为压后测试制度优选提供了理论基础。
Focusing on tight and low permeability gas reservoirs in western Sichuan,by researching filter loss and flowback of fracturing liquid,rules of backflow and sedimentation of propping agent,an idea of dynamically optimizing the chokes for well testing after fracturing in different periods is proposed,related calculation formulae and their field practice are given.The results provide a guide for optimizing the chokes for gas well testing after fracturing.
