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。
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. o The quantitative calculation of coal bed gas can be reached by with density and using resistiw ity parameters estimates the extent of porosity and gas saturation in coal bed.
