以测井、储层物性、三维地质模型的渗透率属性资料以及实际注采资料为基础,分别从储层的测井曲线特征、储层构型特征、注采信息3个方面对昆北油田切六区路乐河组的储层连通性进行了研究。研究结果表明:两井测井曲线呈箱型,井间储层连通性较好;测井曲线呈指状,连通性变化较大;测井曲线呈钟型,下部连通性较好,上部较差;测井曲线呈漏斗型,上部连通性较好,下部较差;测井曲线呈齿型,连通性较差;两口井曲线特征差异较大,储层连通性较差;自然电位明显负异常及自然伽马值较低时,曲线越光滑则连通性越好。水下分流河道和河口坝单一构型单元连通性较好,席状砂构型单元连通性有好有差,其他构型单元连通性较差;水下分流河道与河口坝、水下分流河道与席状砂复合构型单元连通性较好,其他复合构型单元连通性较差;加积型叠置的构型单元连通性较好,其他叠置类型的构型单元连通性较差。产液井的产液量增长比例越大,表明其与注水井井间储层的连通性越好。
Based on well logging, reservoir physical property, permeability property data of 3D geological model and actual injection data, the paper analyzes the well logging characteristics, reservoir configuration characteristics and injection and production information respectively from three aspects: The connectivity of reservoirs in the Lele Formation of Sixth District was studied. The results show that the logging curves of the two wells are box-shaped with good connectivity between the wells. The logging curves are finger-like and their connectivity changes greatly. The logging curves are bell-shaped and the lower connectivity is better. The logging curve is funnel-shaped, the upper connectivity is better and the lower is worse; the logging curve is tooth-shaped and the connectivity is poor; the curves of the two wells are quite different and the reservoir connectivity is poor; the natural potential is obviously negative When the abnormality and the natural gamma are low, the smoother the curve is, the better the connectivity is. The connectivity of single structural units of underwater distributary channel and mouth bar is good, the connectivity of structural units of sand-shaped sand structure is good and bad, while the connectivity of other structural units is poor; underwater distributary channel and estuary dam, underwater distributary channel The results show that the structural elements of the composite sand-shaped sand have good connectivity with other structural elements of the sand-like sand, while the connectivity of the other composite structural elements is poor. The structural elements of the superimposed superimposed structures have better connectivity and the structural elements of other superimposed types have less connectivity. The larger the proportion of liquid production in a production well, the better the connectivity between the production well and the injection well.
