摘    要:从受沉积环境控制的骨架颗粒粒度、成分成熟度、结构成熟度、自生矿物的析出和溶蚀等方面出发,将成岩学与层序地层学结合,研究四川盆地川中地区须家河组储集层次生孔隙发育程度的影响因素。研究认为,沉积环境和层序地层格架对次生孔隙的发育有重要的影响,在水动力强、砂岩成分成熟度较高的沉积环境,次生孔隙发育,物性较好;而水动力较弱、成分成熟度低的砂岩,次生孔隙不发育,物性差;低位体系域砂体较高位体系域次生孔隙发育,特别是在三级层序界面上的砂体,次生孔隙发育,物性好。砂岩的厚度也对次生孔隙有较大的影响,厚度大的砂岩物性较好。粒度粗、成分成熟度高且处在低位体系域的厚层砂岩,次生孔隙较为发育,为研究区下一步勘探和开发的有利区带。图14参18

关 键 词:四川盆地  次生孔隙  沉积环境  层序地层

Abstract:The influence factors on secondary porosity of the Xujiahe Formation clastic reservoir in the central Sichuan Basin were studied from the aspects of grain size,compositional maturity,textural maturity,authigenic mineral precipitation and dissolution under control of sedimentary environment,combined with the sequence stratigraphy.The sedimentary environment and sequence stratigraphy framework have significant influences on secondary porosity.High energy sedimentary setting and high compositional maturity are...
Keywords:Sichuan Basin  secondary porosity  depositional environment  sequence stratigraphy
