Oil and gas enrichment law of Jurassic in Pengyang Oilfield,Ordos Basin
Online published: 2013-10-08
The reservoir of Yan’an Formation in Pengyang Oilfield is dominated by structure and it is characterized by fast lateral variation,complex reservoir formation relation and low degree of exploration knowledge.Based on core, logging and analytic data,this paper discussed the geologic conditions and reservoir formation models in detail by using the theory of sedimentology and petroleum geology.The result shows that this area is rich in 0il and gas.with well reservoir conditions and multiple reservoir-seal assemblages.Oil and gas accumulation is mainly controlled by hydrocarbon source rocks,depositional system,reservoir properties,structure and rock features.The optimization matching of these factors is the key point to find lithologic—structural reservoir of Yan 9 member to Yan 7 member.
