靖边青阳岔油区低阻油层形成因素分析

Analysis of forming factors of the low resistivity reservoir in the Qingyangcha oilfield in Jingbian

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 the low resistivity reservoir in the Qingyangcha oilfield are studied in respects of reservoir structure,physical properties and fluid properties.The additional electric conductivity of clay minerals,the long oil-water transition zone due to low relief of reservoir structure,and the variety of salinity had worked together to form the low resistivity reservoir in this area.The study on the forming factors of the low resistivity reservoir may guide future exploration in this area,and is helpful to later development adjustment.
