摘要
下寺湾油田在延长组长9段致密砂岩油藏的勘探中虽取得了新发现,但整体勘探开发进程较慢,主要是其储层致密、非均质性强,整体单井产量低。为进一步探索延长组长9段致密砂岩油藏的勘探前景,本文利用岩心、测井、测试等资料,对长9段致密砂岩油藏的成藏条件和主控因素进行了详细的分析总结。研究成果表明,长9段致密砂岩油藏的成藏主要受"优质的烃源岩"、"优越的沉积微相之下优良的储层物性"和"较高的过剩压力差"共同控制。
Although there is a new discovery about the exploration of Chang 9 Member tight sandstone oil reservoir of Yanchang Formation in Xiasiwan oilfield,aiming at the reasons of its tight reservoir,strong heterogeneity and low single well productivity,the overall exploration and development is slower.In order to further explore the exploration prospect about Chang 9 Member tight sandstone oil reservoir of Yanchang Formation,the data of the core,well logging and laboratory analysis and test are fully used to carefully analyze and summarize the hydrocarbon accumulation conditions and main controlling factors of Chang 9 Member tight sandstone oil reservoir.The research shows that the accumulation of Chang 9 Member tight sandstone oil reservoir is mainly jointly controlled by high quality source rocks,excellent reservoir properties under favorable sedimentary microfacies and higher excess pressure difference.
