辽河坳陷东部凹陷辉绿岩油气藏储集特征
|
摘要
在对辽河坳陷东部凹陷辉绿岩岩石学研究的基础上,对储集空间类型、形成机理、储集性能及影响储集性能的控制因素等方面进行了分析,认为:古近系辉绿岩主要侵位于古近系沙三段和沙一段中,为东营中、晚期侵入,属碱性系列;辉绿岩储集空间类型及组合方式复杂多样,次生储集空间(尤其是裂缝)占主导地位,其形成受侵入时间及其侵入后所经历的后生改造作用等因素控制;储层多为低孔低渗储层,裂缝对物性改善具重要作用,储集性能受岩相、构造作用、成岩作用等多种因素控制;岩体成藏受油源、储集性能及侵入期等多因素综合控制。
This paper carries out research on the petrology of diabase in the Eastern Sag,Liaohe Depression,aiming to analyze the reservoir space types,formation mechanism,reservoir physical properties and their controlling factors.The result shows that :(1) Most of the Pelogene diabase,belongs to alkaline serial,intruded in Es3 and Es1 of Paleogene,happened during the middle and late Dongying deposition period respectively.(2) The reservoir space and combination of diabase reservoir are complex,of which the secondary storage space(fractures) is principle,affected by the time of intrusion and the transformation experienced after the intrusion.(3) Most of the reservoir has low porosity and permeability.The fractures are of great importance to the improvement of the physical property,affected by lithofacies,tectonic,diagenesis and many other factors.(4) Hydrocarbon accumulation is controlled by source rocks,reservoir physic properties and intrusive period and many other factors.
