从油藏构造、储层物性、流体物性等方面研究了青阳岔油区低阻油藏形成因素。黏土矿物的附加导电性能、油藏构造起伏幅度较低造成的油水过渡带较长及较大变化的矿化度,共同造成了该区域油层的低阻。低阻油藏形成因素的研究对该区域低阻油藏的下步勘探部署有一定的指导意义,同时对开发区的后期调整也具有一定的借鉴作用。
The forming factors of low resistivity reservoirs in Qingyangcha oil region are studied from aspects of reservoir structure, reservoir properties and fluid properties. The additional conductive properties of clay minerals, the longer oil-water transition zone caused by the lower amplitude of reservoir structure fluctuation and the greater variation of salinity, together result in low resistance of the oil layer in this area. The research on the formation factors of low-resistivity reservoirs has certain guiding significance for the next exploration and deployment of low-resistivity reservoirs in the region, and at the same time it also has certain reference function for the post-adjustment of development zones.
