摘　　要：通过对苏德尔特油田兴安岭储层的岩心样品进行储层物性分析和统计,利用X-衍射法测量粘土矿物、压汞法测定孔隙结构、储层敏感性测定、启动压力梯度测定和油水相对渗透率曲线检测等室内实验手段,综合评价和分析了该地区兴安岭储层的基本物性和渗流特征。结果表明,兴安岭储层属于强水敏、强酸敏和中等速敏的低渗透储层,粘土含量较高,有较高的启动压力梯度,水相相对渗透率较低,两相共渗区较小,含水率上升速度快,注水开发较为困难。According statistical analyzed reservoir properties of core samples from Sudeerte Oilfield,Hailaer Basin,basic properties and seepage characteristics of reservoir were synthetically studied through the method of mercury intrusion for mineral,sensitivity analysis for reservoir,threshold pressure gradient testing,relative permeability curve testing and some other correlative experiments.Results show that Xinganling reservoir has low permeability with high water sensitivity and acid sensitivity and middle water speed sensitivity,this reservoir has a high water containing speed and its hard to develop water flooding because of high clay containing,higher threshold pressure gradient,low water relative permeability and little water-oil mutual penetrate span.
