摘要
以测井资料、岩心化验及试油资料为基础,研究了辽河坳陷太古宇古潜山基性侵入岩脉对内幕油气成藏的影响。通过对基性岩脉侵入后对岩层物性影响的分析,认为基性岩脉侵入有利于提高下方岩层储集性能。通过对基性岩脉侵入时间与古潜山油气充注时间关系的分析,肯定了基性岩脉侵入带对古潜山内幕油气聚集的积极作用。通过岩石学分析,认识了基性岩脉的塑性特征,确定其在古潜山内幕能够成为有效隔层。基性岩脉对古潜山内幕油气成藏影响的研究丰富了辽河坳陷太古宇古潜山内幕油气成藏理论,对辽河坳陷太古宇古潜山内幕油藏的深化勘探具有十分重要的指导意义。
The impact of basic intrusive dyke on hydrocarbon accumulation inside the Archaeozoic buried hill in Liaohe Depression is studied on the basis of logging data, core test and oil testing data. Analysis of the impact of basic dyke intrusion on petrophysical property shows that the intrusion is in favor of improving underlying reservoir property. The relationship between the time of basic dyke intrusion and the time of hydrocarbon charging in buried hill ascertains the active role of basic dyke intrusion on hydrocarbon accumulation inside buried hill. Petrology analysis cognizes the plastic property of the basic dyke and defines that it can become effective barrier inside buried hill. The study of the impact of basic dyke on hydrocarbon accumulation inside buried hill enriches the theory of hydrocarbon accumulation inside the Archaeozoic buried hill in Liaohe Depression and is of significant guiding importance to deepening exploration in this area.
