中文摘要: |
储层的物性是影响油气的聚集、储存和开采的重要地质因素。通过铸体薄片、扫描电镜、岩心分析及测井解释等,对鄂尔多斯盆地靖安油田杨66井区延10储层宏观非均质性进行了研究。结果表明,层内非均质性主要受渗透率非均质性、层理构造和层内夹层影响;层间非均质性取决于分层系数和砂岩密度变化;平面非均质性与砂体在平面上的几何形态及其连通方式和连通程度密切相关。研究区杨66井区延10储层宏观层内非均质性以延1011储层最强,其他各小层次之;层间非均质性延101-11小层较强;平面非均质性延102-11和延102-21小层强。研究区产量薄弱,明确各小层非均质性强弱对于研究区油藏的精细开发及石油稳产具有重要意义。 |

Reservoir heterogeneity is an important geological factor that affects the accumulation, storageand exploitation of oil and gas.The output in the study area is weak, providing a theoretical reference for increasing the output in the area, through casting thin section, scanning electron microscope, core analysis and logging interpretation, etc.,the macro-heterogeneity of Yan 10 reservoir in Well Yang 66 in Jing’an Oilfield was studied. Research indicates,the interlayer heterogeneity is mainly affected by permeability heterogeneity, bedding structure and interlayer;the interlayer heterogeneity depends on the stratification coefficient and the density of sandstone;the plane heterogeneity is closely related to the geometry of sand body on the plane and its connection mode and degree.In the study area, Yan 1011 reservoir is the strongest in the macro heterogeneity of Yan 10 reservoir in Yang 66 well area,other small levels;The interlayer heterogeneity is stronger in the 101-11 small layer. The plane heterogeneity is strong in yan102-11 and yan102-21 sublayers.The production in the study area is weak, and clarifying the heterogeneity of each layer is of great significance for the fine development of the oil reservoirs in the study area and stable oil production. |
