准噶尔盆地车排子凸起石油地质特征及勘探方向

PETROLEUM GEOLOGY FEATURES AND PROSPECTING TARGETS OF CHEPAIZI UPLIFT,JUNGGAR BASIN

准噶尔盆地车排子凸起自早二叠世以来经历了3个发展演化阶段.该凸起长期处于隆起状态,是油气运移的有利指向区,具有"多源供烃、网毯式输导、多期成藏"的有利条件和"多套含油层系、多种油藏类型、多种含油品位"的"三多"油气聚集特点,岩性类、地层类圈闭是凸起的主要勘探目标.该凸起东南部倾没端和西北部山前带是油气勘探的主要方向.

The Chepaizi Uplift in Junggar basin has gone through three evolution stages since Early Permian. Owing to the long-term uplifting in shape, the uplift is a favorable area for the hydrocarbon trend. It has the advantages of ＂multiple hydrocarbon sources, meshwork-carpet type migration, multiphasic reservoir formation＂, with the hydrocarbon accumulation characters of ＂many oil-beating series, multiple reservoir types and oil classes＂. The lithologic and stratigraphic traps, therefore, are the main exploring objects in this uplift; thus, the southeastern pitching end of the Chepaizi Uplift and the mountain front in the northwest are the main targets for searchingr for oil/gas.
