摘　　要：根据玛湖1井区J_(1)s_(2)段的录井、测井等资料,对其储层四性关系及有效厚度下限标准进行研究。研究认为:J_(1)s_(2)段储层的岩性主要为细砂岩,呈中孔、中渗特性;除砂砾岩以外,储层的岩性越粗,其物性就越好,含油级别也越高;砂砾岩的钙质胶结作用和硅质胶结作用导致储层的物性变差,进而影响了储层的含油性。基于此认识,建立了储层岩性、物性、电性及含油性测井解释模型,并运用该模型确定了玛湖1井区J_(1)s_(2)段的储层有效厚度下限标准。Based on the data of logging,analysis and testing of J_(1)s_(2) section in Mahu 1 well block,the four property relationships of the reservoir and the lower limit standard of effective thickness are studied.The results show that the reservoir lithology of J_(1)s_(2) formation is mainly fine sandstone,which belongs to medium porosity and medium permeability reservoir;in the four property relationships,except for sandy conglomerate,the coarser the lithology is,the better the physical property is,and the higher the oil-bearing level is.The calcareous and siliceous cementation of the sandy conglomerate leads to its poor physical property,which affects the oil-bearing property.The logging interpretation model of lithology,physical property,and oil-bearing property is established and the lower limit standard of effective thickness of J_(1)s_(2) section in Mahu 1 well block is determined based on the model.
