煤层气储层测井评价有关问题的讨论

A Discussion on Issues Related to CBM Reservoir Well Logging Evaluation

煤层气的形成和储层的特性决定了煤层气储层评价的一系列关键参数,这些参数可用常规测井方法直接或间接获得。目前常规测井方法包括自然电位、双侧向(或感应)、微电极、补偿密度、自然伽马、声波时差、声波全波列、中子孔隙率以及井径测井等。选用不同测井方法采用线性回归或体积模型等方法,可以获得煤层气储层评价参数。

The formation of CBM and reservoir characteristics fixed upon a series of key parameters to evaluate reservoir, these parameters can be acquired from conventional well logging directly or indirectly. Routine logging methods at present include spontaneous potential, dual lateral （or induction）, micro electric, compensated density, gamma-ray, sonic differential time, acoustic full-wave train, neutron porosity and caliper etc. Using linear regression or volume model in different logging methods can obtain reservoir evaluation parameters.
