中国煤层气聚集单元研究现状

Current Situation of Researching Coalbed Gas Accumulation Units in China

煤层气聚集单元划分与成藏规律研究是进行煤层气资源和选区评价、制定科学的煤层气勘探程序、提高煤层气勘探成功率的重要基础。中国煤层气的形成条件与分布环境十分复杂,聚集单元研究对中国煤层气的勘探评价尤为重要,但目前对含气区或煤盆地内部的聚气单元划分研究还很薄弱,因此,对中国煤层气赋存环境及形成规律、中国煤层气聚集单元的形成、划分、评价方法以及中国煤层气藏的类型、成藏模式等进行深入的研究,不仅对中国煤层气的勘探具有重要的实际指导意义,而且对发展和完善煤层气地质理论也具有重要的科学意义。

Coalbed gas accumulation unit classification and the gas reservoir-forming study are the primary bases to evaluate coalbed gas resource and units, establish the scientific programs for coalbed gas exploration and improve the success ratio of exploration. Because of the complex forming and distributing conditions of coalbed gas in China, it is especially important to study accumulation units to evaluation of coalbed gas exploration. Up to present, few of researches on this aspect have been done. This paper suggested that analyzing the existing circumstance and the forming rules of coalbed gas, studying on the formation and the dividing and accessing methods of coalbed gas accumulation units and researching on the styles and the models of coalbed gas reservoirs are necessary not only for direct exploring coalbed gas reservoir, but also for improving and perfecting the coalbe gas geological theories in China.
