摘　　要：彭阳油田侏罗系延安组油藏受构造控制,储层横向变化快,成藏关系复杂,勘探认识程度较低。综合岩心、测井及分析化验等资料,应用沉积学、石油地质学等理论和方法,对该区油气成藏的地质条件及成藏模式进行了深入探讨。结果表明,该区油气资源丰富,储集条件好,发育多套储盖组合。油气成藏主要受烃源岩、沉积体系、储层物性、构造形态及成岩特征等因素控制,同时,这几个因素的优化匹配是寻找延安组深部延9—延7岩性构造油藏的关键。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 oil 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.
