摘要
针对渤海湾盆地胜坨油田高含水开发后期剩余油分布复杂、认识难度大、措施效果逐渐变差等突出问题,根据沉积学、层序地层学理论和取心井及测井曲线,采用岩性和岩相相结合的方法进行韵律层细分、沉积微相研究,搞清了影响剩余油分布的主要地质因素为韵律层物性变化,明确了韵律层间夹层分布状况。在精细描述韵律层以及夹层的基础上实施了韵律层的井网重组,取得了很好的调整效果。
Aiming at the problem of complex distribution of remaining oil and the poor effect of adjustment in the extra high water cut period, facies. All these are based on sedi factors in the remaining oil distrib conclusion, we reconstruct aper studies rhythmic layering subdivision and sedimentary microogy and sequence stratigraphy. We find that the critical geologic ution are the properties of rhythmic layering and the interlayers. Based the well pattern of rhythmic layering and achieve a good result.
