摘要
储层非均质性是沉积、成岩和构造因素共同作用的结果,研究储层非均质特征及控制因素对分析剩余油分布规律、调整开发方案、提高剩余储量等具有重要意义.运用储层沉积学原理,利用测井、钻井资料对研究区地层进行精细划分与对比,研究松辽盆地榆树林油田扶杨油层储层非均质性.结果表明:扶杨油层在层内、层间和平面上均表现为不同程度的非均质性,其中扶Ⅲ油层组非均质性最弱,杨Ⅰ油层组非均质性相对较强;扶杨油层的非均质程度主要受沉积相的控制.
Reservoir heterogeneity is caused by the interaction of sedimentation,diagenesis and structure factors.It is very important for researching residual oil distribution law,adjusting development project and improving remaining reserves to study reservoir heterogeneity characteristics and reservoir controlling factors.Using of logging,drilling data and the principle of reservoir sedimentology,reservoir heterogeneity of Fuyang Reservoir is quantitatively studied by finely classifying and comparing study area formation in Yushulin oilfield of Songliao Basin.The result shows that reservoir heterogeneity of different intensity occurred in laminates,interlayer and plane of Fuyang Reservoir.The heterogeneity is the weakest in Fu Ⅲ reservoir,and it is relatively stronger in Yang Ⅰ reservoir.The sedimentary facies is the main factor for effecting the reservoir heterogeneity analysis of Fuyang Reservoir.
