摘要:

变浅暴露滩微相的岩石组合是孔隙层和储渗体形成的基础。孔隙层以残余粒间孔和次生溶孔为主,有两种孔隙~吼道组合,主要为II、III类储层。孔隙层呈透镜体展布,在背斜圈闭内可形成三种类型的储渗体和相应的气藏类型。嘉二段滩微相组合的气藏其有现实和长远的勘探开发前景。

Abstract:

The rock assemblage of shallow exposed bank—microfacies is the basis of the formation of pore layers and reservoir permeability systems. The pore layers are dominated by remnant grain—to—grain pores and secondary corrosion pores. There are two types of porethroat association which are mainly Type II and Type III reservoirs. The pore layers stretch in the shape of a lens and may form three types of reservoir permeability systems and corresponding gas pools types within anticlinal trap. The gas pools of bank—microfacies assemblage in 2—section of Jia Ling River group are sure to have practical and long—term exploitation prospect.

Key words: Reservoir, Bank facies, Reservoir permeability system, Gas pool exploration, 2—section of Jia Ling River group
