摘　　要：低电阻率油层类型繁多,成因不一。以济阳坳陷东营凹陷沙三段高阻、低阻油藏为例,分析了储层孔隙结构及低电阻率油层之间的关系。研究表明,储层微孔隙发育与低电阻率油层之间无直接的因果联系。引起油气层低电阻的因素是多方面的,根本原因是储层具有相对弱的成藏动力,致使油层现今的含油饱和度相对较低。Low-resistivity reservoirs had many types and different geneses.The relationship between reservoir pore structure and low-resistivity reservoirs was analyzed by taking Es2 high and low resistivity reservoirs of Dongying Sag in Jiyang Depression for example.The research suggests that there is no direct causal relation between reservoir pore structure and low-resistivity reservoirs.There are many kinds of factors which result in low resistivity,a fundamental factor is the weak reservoir-forming dynamics,which causes relative low oil saturation of reservoirs.
