| 摘 要： | 在煤层气测井中，利用自然电位和双侧向电阻率可以定性判断含气层位。利用电阻率参数可推算煤层的孔隙度和含气饱和度，结合密度对煤层气可以进行定量计算。．

| Abstract: | 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. |
| |
| Keywords: | permeability extent of porosity gas saturation density gas content |
