低阶煤盆地煤层气勘探的几点思考

STUDY ON COAL BED GAS EXPLORATION iN Low RANK COAL BASIN

通过对低阶煤盆地煤层孔隙结构的分析,指出了低阶煤盆地在煤储层性质、煤层含气性方面的种种特殊性,指出目前应用于中-高煤阶煤盆地勘探与研究的技术系列不完全适合于低阶煤盆地。分析了影响低阶煤盆地煤层气勘探的主控因素。提出了加快中国煤层气产业发展步伐的建议。

Through analysis of the coal - bed pore texture in low rank coal basins, special reservoir properties and oilbearing nature of the coal beds are pointed out. It is concluded technology currently used in the exploration of medi- urn to high rank coal basins is not fully fit for the low rank coal basins. Primary factors influencing the exploration of coal - bed gas in low rank coal basins are analyzed. At last suggestions on speeding up the coal - bed gas industry development are put forward.
