Title: Logging evaluation method of reserve parameters of carbonate gas reservoir
Abstract: Both the oil and gas reserves and production contained in carbonate oil and gas reservoir exceed half of the total oil and gas production, so it is significant to carry out study on reserve parameter evaluation of carbonate oil and gas reservoir. Carbonate reservoir is characterized by complex lithologies, various types of reservoir space, markedly changed secondary pores and strong heterogeneity, which makes the porosity and permeability evaluation difficult in the reserve calculation. Taking a marine carbonate gas field as an example, based on conventional log data, this paper conducted integrated studies on dual-medium reservoirs from the aspects of lithology identification, calculation of porosity and permeability and fracture identification. The result shows that conventional log data can be use to identify the lithologies and fractures of carbonate reservoir effectively, can be applied to quantitatively calculate the porosity and permeability of primary pores, dissolved shrinkage pores and fractures of dual-medium reservoir, and can be used to establish the criterion for quantitative fracture identification. This study can provide reference for the study of dualmedium reservoir when there is lack of core and image logging data.
