小层的精细划分与对比是进行沉积微相、储层评价及剩余油分布研究的基础。本文在分析地区背景、区域地质资料的基础上,针对研究区高台子油层低渗透砂岩的特点,开展油藏小层精细划分对比及小层砂体连通性分析,为优化注水开发方案和选用先进注采配套工艺技术措施提供了比笼统注采更为精细的开发地质依据。
The fine division and contrast of small layers are the basis for the study of sedimentary microfacies, reservoir evaluation and remaining oil distribution. Based on the analysis of regional background and regional geological data, aiming at the characteristics of low permeability sandstone of Gaotaizi reservoir in the study area, the paper makes detailed comparison of subtle reservoirs and analyzes the connectivity of small sand bodies so as to optimize the water injection development scheme and selection Note supporting mining technology and measures provide a more refined than the general injection of the development of geological basis.
