摘要
In coal bed gas logging,both the methods of spontaneous potential logging and Rd investigate double lateral resistivity logging can qualitatively identify the level of gas in coal.The quantitative calculation of coal bed gas can be reached by with density and using resistivity parameters estimates the extent of porosity and gas saturation in coal bed.
