摘　　要：八面河地区面14井区Es64砂组低阻油层发育,根据面14井区Es64砂组的沉积环境、储层的微观特征、粘土矿物的含量及成分、微观孔隙的导电机理等方面对其成因进行研究和探讨。综合分析了造成低阻的主要因素,并依据试油试采资料,利用地质统计法建立了低阻油层的识别图版;通过创立测井曲线的＂三性＂对比法识别低阻油层的方法,取得了较好的应用效果。Low-resistivity reservoirs were developed in 6 sand formations in fourth member of Es4 of Wellblock Mian 14 in Bamianhe Area,its genesis was studied and discussed according to the depositional environment,microscopic features the formations,the content and composition of clay minerals and the conduction mechanism of microscopic fractures.The major influencing factors of low resistivity are comprehensively analyzed and the formation test and production test data as well as geologic statistical method are used to establish an identification chart-board of low resistivity reservoirs.The method of 'four properties' is used for identifying the low resistivity reservoirs with better effect.
