Abstract

Abstract:

Many parameters extracted from mercury injection curves have been used to describe the character of reservoir pore structures. In this paper, a new pore-structure parameter, RApex, derived from mercury injection capillary pressure data is introduced. The physical meaning of RApex is the pore throat radium of a pore system with good internal connection and continuity formed when mercury is injected into the rock sample. The procedure to obtain RApex is described. Applications of RApex are illustrated with a gas-field case study in which the parameter was used for grading reservoirs and delineating stratigraphic positions favorable for hydrocarbon accumulation, and satisfactory results were obtained.

Key words: Pore structure, Pore throat radius, Reservoir evaluation, Hydrocarbon accumulation
