摘要:

准噶尔盆地陆梁隆起不整合面十分发育,且与油气运聚关系非常密切:二叠系、三叠系底不整合面是该区侏罗纪末成藏的主控因素,侏罗系底不整合面是深部油气进入该系的有利通道,而白垩系底不整合面又是油气顺利从侏罗系进入白垩系的必要条件。研究区的不整合面有褶皱、断褶、超覆、削截、平行5种类型,各种类型的不整合面对研究区油气运聚作用也有着差异,其中断褶不整合面对油气的垂向运移与聚集作用最大,是研究区最为典型的油气成藏方式。不整合面的分布具有差异性、继承性、迁移性,三性对油气的演化和分配有着影响作用。

Abstract:

There were abundant with unconformity surfaces in Luliang uplift in Junggar basin which were significant to the hydrocarbon migration and accumulation. The unconformity surface in the bottom of Permian system and Triassic system was key factor for hydrocarbon accumulation in the late period of Jurassic; the unconformity surface in the bottom of Jurassic system was favorable migration path for hydrocarbon accumulation in Jurassic system; the unconformity surface in the bottom of Cretaceous system was necessary element for the hydrocarbon from Jurassic system to come to Cretaceous system. There were five unconformity types, which played different roles on the hydrocarbon migration and accumulation in the research section. The distribution of the unconformity has "three characters": difference, succeed, and transfer, which had great influence on the hydrocarbon distribution and reallocation.
