大庆油田古1区块黑帝庙油层沉积微相研究

Research on Sedimentary Microfaceis of Heidimiao Reservoir in Gu 1 Block of Daqing Puxi Oilfield

古1区块构造位置处于松辽盆地中央坳陷区葡西鼻状构造的前缘轴部,研究层位为黑帝庙油层。通过对研究区黑帝庙油层组6小层310口井的测井资料分析,将每口井细分至单砂体级别的10个沉积时间单元,并进行精细统层对比,建立了测井相模式,确定了10个沉积时间单元的平面微相特征。

The structural position of Gu 1 block in Puxi oilfield is located in the leading edge of the shaft portion of Puxi nose structure which is located in the central depression area of Songliao basin, and the research layer is Heidimiao reservior. Based on analysis of the logging data about 310 wells covering six layers of Heidimiao reservior in research area, each well was subdivided into 10 depositional time units in the level of the monosandbody, and fine contrast was carried out, the logging facies model was established, and then the microfacies characteristics of the 10 depositional time units were identified.
