Abstract:

The tight limestone of Da’anzhai member in the central Sichuan Basin belongs to typical “tight oil” reservoir. The reservoir lithology was reclassified to crystallized shelly limestone, argillaceous shelly limestone, micrite shelly limestone and crystalline limestone. The characteristics of four types of reservoir space were studied, including dissolved pores-vugs, secondary micropores, fractures and nanopores, and a reservoir space model for tight limestone was established, which seems like a“nets-system”. Through the analysis of the effects of sedimentary microfacies, dissolution and tectonism on the reservoir, it was pointed out that the matrix pores mainly developed in low energy shell beach, and dissolved pores-vugs mainly developed in high energy shell beach. The reservoir development model is a kind of combination by multiple reservoir space types, which distributed largely and continuously. The “sweet spot” of tight limestone is the pores-vugs-fractures reservoir developed on the area where are full of matrix pores and dissolved pores-vugs.
