通过岩芯、岩石学特征、测井、地球化学、沉积构造等相特征进行沉积环境研究,不但确定了南翼山新近系上油砂山组属浅湖、半深湖亚环境,还进一步划分出颗粒滩、灰泥坪、云泥坪、砂泥坪和泥坪等五个微相。同时还对不同微相的含油性作了客观的探讨。建立了该区储层沉积相模式,为下一步寻找油气富集带提供依据。 The study of sedimentary environment through core, petrological characteristics, logging, geochemistry and sedimentary facies, not only confirmed the sub-environment of shallow sands and semi-deep lakes in the Nanshan Mountains, but also further classified Particle beach, plaster Ping, cloud mud Ping, sand mud Ping and mud Ping five micro-phase. At the same time, the oiliness of different micro-phases was also discussed objectively. The reservoir sedimentary facies model of the area is established, which provides the basis for finding the hydrocarbon enrichment zone in the next step.
