摘要: 松辽盆地长岭断陷营城组火山岩厚度大,岩石类型多,相态类型齐全。对火山岩储层微观特征进行系统观察分析,初步研究其形成机理。将火山岩储层形成划分为2个阶段:初始成岩作用阶段和成岩后生作用阶段。初始成岩作用形成原生孔隙;成岩后生作用形成次生孔隙;构造作用贯穿成岩的全过程,形成原生和次生各类各级别的裂缝;深部热液及生排烃作用对储层的改造作用明显。多期大规模构造运动是火山岩地层成为优质储层的主要动因。深部大量发育的优质火山岩储层具有巨大的勘探潜力。Abstract: The volcanic rock of Yingcheng Formation in the Changling Faulted-Depression of the Songliao Basin is thick with various types and facies.Microscopic characteristics and formation mechanism of volcanic rock reservoirs have been systematically observed.Formation of volcanic rock reservoirs is divided into 2 stages,the initial diagenesis stage and the later diagenesis stage.During the initial diagenesis stage,primary pores are formed.And in the later diagenesis stage,secondary pores are formed.Tectonic effects take place through out both the 2 stages,forming various primary and secondary cracks.Deep hydrothermal flow and hydrocarbon-generating effects have obviously transformed reservoir.Many large-scale tectonic movements are the main reasons that volcanic rocks turn to high quality reservoirs.Substantially developed high quality volcanic reservoirs in deep formation have enormous exploration potential.
