| 摘 要： | 低渗透油气藏具有孔隙半径小,油气相渗透率低等特点。由于外来液的侵入,在低渗透油气井钻完井中容易造成水锁伤害,大大降低油气产量。本文通过对水锁伤害的影响因素分析,认为水锁伤害是多方面因素共同作用的结果,并归纳出目前解除水锁伤害的主要研究现状,对系统研究水锁解除技术有重要参考意义。

| Abstract: | Low permeability oil and gas reservoir characterized by small pore size and low permeability.More and more attention has been paid to the development of low permeability reservoir.Water-blocking damage occurred because of permeability loss near well-bore area when work fluid encroached into the reservoir,Water-blocking can severely damage the production of oil or gas wells.This paper analysis the factors that can cause water-blocking,summarize the main methods of cleaning-up of water blocking and give sugge... |
