摘　　要：针对垦利油田低渗透砂岩油藏特点及生产现状,根据储层特征及注水、采油和增产措施过程中各种入井流体与地层配伍性的试验资料,研究了注水、采油和措施作业等过程中储层伤害的类型和机理,并据此机理实施了一系列的储层保护和治理措施,取得了明显的效果。In consideration of the characteristics and production situations in the low permeability reservoirs of Kenli Oilfield,the type and mechanism of formation damage caused in water injection,production and the operation of stimulation are studied on the basis of reservoir properties and test data of compatibility of various fluids with formation during the water injection,production and stimulation.A series of measures are implemented for reservoir protection and damage control according to the mechanism stated above,by which obvious effect is obtained.
