利用岩芯、测井及各种分析化验等资料,通过对各种沉积相识别标志的分析,研究了沈家铺油田枣Ⅴ油组沉积相、沉积微相类型及其特征,认为本区枣Ⅴ油组为扇三角洲前缘亚相沉积,主要微相类型有水下分流河道沉积、水下分流次河道沉积和水下分流河道间沉积。在此基础上,利用岩石热解(Rock-eval)和薄层色谱(TLC-FID)等地球化学分析技术,定量评价了各微相的含油性,这种尝试具有一定的理论意义。 Based on the analysis of sedimentary facies identification marks, the sedimentary facies, sedimentary microfacies and their characteristics of Jujube Ⅴ oil group in Shenjiasu Oilfield are studied by using core, well logging and various analytical tests. It is concluded that the jujube Ⅴ oil group is fan delta front subfacies deposition, the main microfacies types are underwater distributary channel deposition, underwater distributary sub-channel sedimentation and underwater sediment deposition. On this basis, the geochemical analysis techniques such as rock-eval and TLC-FID are used to quantitatively evaluate the oil content of each microfacies. This attempt has some theoretical significance.
