Abstract

Abstract: The technology that to determine the cut-off value of extremely low permeability clastic reservoir in Anpeng Oilfield,Biyang Depression, was described. The depositional facies of reservoir is a fan-delta system. The types of oil and gas reservoirs are complicated. There are black-oil reservoir, volatile oil and condensate gas reservoir. The reservoir features are extremely low permeability and low naturalwell production. Through evaluation study of reservoir, three methods to acquire cut-off value of reservoirs which bearing various fluids was presented,with Hobson method, production ability method and buoyancy method. In the end, the cut-off value for the effective development of extremely low permeability oil and gas field was proposed.

Key words: complicate oil and gas reservoirs, extremelylow permeability reservoirs, effective fracturing cut-off values
