摘　　要：为了搞清松辽盆地北部大庆长垣以西地区黑帝庙油层成藏规律，开展了高分辨率层序地层学、沉积相和砂体分布研究。利用地震、钻井及测井等资料在嫩江组二、三段识别出3个准层序组、12个准层序，研究认为嫩江组二段沉积时期形成的沉积体系组合为高位体系域，整个嫩江组三段形成一个完整而典型的收缩体系域，低位体系域主要分布在嫩江组四段；嫩江组二、三段主要发育三角洲沉积、浊积沉积和三角洲间湾3种沉积体系，主要为半深湖沉积环境，嫩江组三段上部发育三角洲平原相；由于受茂兴地区的南部物源及泰康以东地区的北部物源控制，黑帝庙油层储集砂体在齐家一古龙地区具有由下到上、由东向西层层尖灭发育的特征，预测出黑帝庙油层发育4个油气聚集有利区带和1个远景带。In order to make clear of the reservoir-forming laws of Heidimiao oil reservoir in West Daqing Placanti- cline of North Songliao Basin, the studies on high-resolution sequence stratigraphy, sedimentary facies and sand- body distribution are conducted. By means of seismic ~ drilling, well logging and another data, there are three sub- sequence sets and twelve subsequences are recognized in NO. 2 and 3 Members in Nenjiang Formation. The studies show that the combination of the sedimentary systems formed in the depositional period of NO. 2 Member in Nen- jiang Formation is located in highstand systems tract, the whole NO. 3 Member in Nenjiang Formation forms a com- plete and typical shrunk system tract, the lowstand system tract is mostly distributed in NO. 4 Member of Nenjiang Formation; Three depositional systems including delta, turbidite and interstitial bay among the deltas are developed in NO. 2 and 3 Members of Nenjiang Formation, which are characterized by semi-deep lake sedimentary environ- ment, the delta plain facies is developed on the top of NO. 3 Member of Nenjiang Formation; controlled by thesouthern source in Maoxing region and the northern source to East Taikang, the sandbodies in Heidimiao oil reser- voir are featured by the pinchout development from top to bottom and from east to west, 4 favorable hydrocarbon ac- cumulation belts and 1 play are predicted in Heidimiao oil reservoir.
