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
