摘  要：
徐深气田A区块在营城组火山岩中获得工业气流,区块内各井的产量存在较大差异,这主要是与火山岩储层储集空间的发育程度及火山岩体的分布特征有关。为研究储层的分布特征,寻找有效储层发育区,对区块火山岩储层储集空间特征与成岩作用的关系进行了深入的研究。通过岩心、薄片、扫描电镜等资料的分析研究,确定该区块储集空间有原生和次生2类,原生储集空间以气孔发育比例较高,次生储集空间以发育溶蚀孔和裂缝为主。火山岩储集空间的发育演化决定于成岩作用,挥发分的逸散作用、溶解作用、构造作用和风化作用、冷凝(却)收缩作用,均是有利于储集空间形成的具有建设性的成岩作用;矿物的多形转变作用、熔浆胶结作用、压结作用、压溶作用、交代作用、充填作用、熔结作用、均是对储集空间具有破坏作用的成岩作用。

摘  要：
There is industrial gas flow in volcanic rocks of Block A of Xushen Gas Field of Yingcheng Formation,the differences of output between the block wells are great,this has relationship with the distribution characteristics of volcanic rock and development degree of pore space of volcanic reservoir.In order to study the volcanic reservoir distribution and look for effective development area of the reservoir,the relationship between the reservoir pore space of the volcanic characteristics,it's diagenesis is researched.Through the analyses of cores,thin section,scanning electron microscopy(SEM) data,it is determined that the reservoir space has primary and secondary reservoir spaces,the ration of primary reservoir space developed in porosity is higher,the secondary reservoir space is mainly developed dissolution holes and cracks.The development and evolution of volcanic reservoir space are determined by diagenesis,which is beneficial for the formation of reservoir space of constructive diagenesis,which include dissolution,condensing(cooling)contraction,the scatteration of the volatile component,tectonism and weathering;and destructions of the diagenesis of the reservoir space,wuich include filling,dissolving,pressure solution,the cementation of lava,metasomatism,the polymerphic transformation of minerals.
