摘要
以大庆油田杏十二区复合驱试验区为例,针对厚油层开展了垂向的精细识别。利用3727井层有效砂体数据,建立河道类别判定标准,划分出了6个沉积时间单元的河道砂体。通过对河道切叠关系的进一步认识,将小层内原有的单河道砂体细分为多河道砂体。建立了研究区复合河道砂体空间叠置关系,识别出了单独的骑墙河道,为探究厚油层不同沉积微相类型的井间连通关系打下了基础。
Taking the compound flooding test area in Xing Twelve Area of Daqing oil field as an example,the vertical fine recognition ofthick reservoirs was carried out. By using the effective sand body, s data of 3727 well layers, Criteria for classification of river courses were established,and six sedimentary time units were divided for sand body, s of river courses. Through the further understanding of re-lationship between channels＇ cut pile,the authors subdivided the original single channel sand body inside the small layer into multiple channel sands bodies. They established a composite superimposed channel sand body space relationship in study area, identified the sin-gle straddling channel, and has lain the foundation of thick reservoirs connection relationship between wells of different sedimentary mi-crofacies.
