Abstract

Reservoir Classification and Evaluation is an important section in the process of the research for reservoir development. Based on the analysis of core capillary pressure data, this research proposed: The relationship between R35 (Mercury enters the saturation of 35% corresponding to the pore throat radius) and permeability (K), porosity ( ); Establishment of classification and evaluation chart with the parameters such as R35, K, , for the LS gas field. By putting a large number of conventional core analyzing data of the physical properties on the chart, the quality of each gas formation in accordance with the core could be evaluated. For the same formation, the significant change of the parameters (R35, K, and ) could indicate that the reservoir has a severe heterogeneity. For example, after analyzing the main factors of diagenesis which affect reservoir heterogeneity through the thin slice identification, scanning electron microscopy and other laboratory data of E15 reservoir, the conclusion could be obtained: Dissolution is the most significant factor which influences the heterogeneity of the reservoir. The reservoir classification and evaluation Chart of R35 could help to evaluate the reservoir physical properties intuitively and efficiently.
