摘要
旅大5-2油田的主力储层为东二上段,高孔高渗,粘土矿物绝对含量低。通过岩心敏感性流动实验,研究该储层潜在伤害因素。研究表明,速敏损害程度为无-弱,水敏损害程度总体弱至中等偏强,无酸敏损,碱敏损害为弱中等偏弱。
The main producing layer of Luda 5-2 oilfield is the second part of Dongying formation,which is of high porosity and permeability,low clay mineral absolute content.The author researches reservoir potential damage factors by the core sensitivity experiments.Results show that the speed sensitivity is from zero to weakness,the water sensitivity extent is from weakness to medium strong.There is no acid sensitivity,and the alkali sensitivity extent is from weakness to moderate weakness.
