Abstract:

Jiyuan area is one of the key oil and gas exploration area within the basin. Based on the research of source rocks, reservoir rocks, hydrocarbon migration and traps, this paper synthetically analyzed the hydrocarbon accumulation conditions of Chang 2 oil reservoir set in Jiyuan area. The result shows that hydrocarbon of Chang 2 oil reservoir set mainly comes fromChang7 source rocks. The reservoir in the study area is mostly underwater distributary channel sand bodies, and sandstone is mainly composed of arkose, lithic arkose, with little feldspathic lithic sandstone, so it belongs to moderate porosity and low permeability reservoir. Compaction, cementation and dissolution are the main diagenesis types. The abnormal high pressure from Chang 7 oil reservoir set drives the oil generated from Chang 7 source rocks up to Chang 2 oil reservoir set. The oil in Chang 2 oil reservoir set is mainly trapped by structural-lithologic trap, with local area by structural trap and lithologic trap. The thick interdistributary mudstone developed in Chang 2 oil reservoir set plays the necessary role as the shield and cap rock ofChang2 oil reservoir set.
