摘　　要：根据钻井岩心及薄片观察,结合压汞及测井等资料对鄂尔多斯盆地靖边气田南部Mu1-4碳酸盐岩储层特征进行研究。储集岩以膏核、膏模溶蚀孔洞状泥—细粉晶白云岩为主,其孔喉结构多为大中孔,粗中喉;储层类型以裂缝—溶蚀孔洞型为主;测井响应特征是声波时差值高、中子值高、自然伽马值低、密度值低、有效光电吸收截面指数值低、电阻率值相对降低;总体是一低孔低渗的岩溶储层。本次研究以测井解释资料为基础,结合取心井的储集岩类型、孔喉结构和物性特征等对研究区Mu1-4储层进行有利区域的评价。Based on observation of drilling cores and thin slices,combined with mercury injection and logging data,the carbonate reservoir characteristics of the Mu1-4 member,which is located in the south of Jingbian Gasfield in Ordos Basin,was studied.The study shows that the main reservoir lithology is gypsum concretion,gypsum concretion corrosion pores mud-crystal powder dolomite;the main pore texture is coarse-medium pore,coarse-medium pore throat;the main reservoir type is crack-vogular pore space and vogular pore space;the characteristics of log response is high AC,high NL,low GR,low DEN,low RT,low RT;the gasfield is a karst reservoir with low-permeability and low-porosity.Based on the logging response of target layer,combined with reservoir lithology kind,physical property and pore throat structures etc.,the beneficial region of Mu1-4 reservoir was evaluated.
