摘要
新疆煤层气资源丰富,加强煤层气主控因素和优选有利的勘探目标是新疆煤层气获得突破的关键因素。作者针对新疆低煤阶煤层气的特点,探讨了新疆煤层气地质选区评价的关键因素及新疆低煤阶煤层气地质选区评价方法。煤层气地质选区评价方法可分为两步走,第一步为综合选区阶段,应用一票否决制进行有利区选择,第二步为有利区预测阶段,根据有利区预测标准,应用预测公式进行分级,评价煤层气勘探目标区,为新疆煤层气产业大发展打好基础。
Xinjiang has abundant coalbed methane resources. The key factor for making a breakthrough in development of CBM in Xinjiang is to strengthen study of CBM controlling factors, and to select the favorable target areas. The authors have discussed the key factors in evaluation of the selected geological target areas in Xinjiang, and the evaluation method based on the characters of CBM in low rank coal. The evaluation method consists of two steps. The first step is to make a comprehensive evaluation of the selected areas. One-votedown system is applied in selection of the favorable target areas. The second step is to forecast the favorable areas. That is, to classify and evaluate the exploration target areas by using the predicting standards and formulae, in order to lay a good foundation for development of CBM industry in Xinjiang.
