摘要
研究表明:大民屯凹陷西斜坡中段沙四段主要发育3个扇体;扇体间沉积不同,期次不等时,分扇体分别划分期次,细分地质评价研究单元15个;细分单元用优势岩性约束结合有效厚度约束的方法可对各扇体各期次优势储层分布有效刻画。经过验证,钻井均钻遇油层,证实该方法在本区具有一定的可操作性。
The research shows： In the fourth section of the middle section of the west slope in Damintun depression, there are mainly 3 fan bodies developed. They are different in the the interbody deposition and the period. Divided fans are divided into stages respectively, and the division units are divided into 15 geological evaluation research units. The subdivision units can be effectively depicted by the method of dominant lithology constraint and effective thickness constraint. After verification, drilling has been encountered in the reservoir, which proves that the method is feasible in this area.
