目前,霍西盆地因尚未进行有效的资源勘查潜力评价,研究工作迫在眉睫。灰色聚类法适用于外延明确、内涵不明确的对象,因霍西盆地资料较少且数据不全,勘探潜力评价还有许多灰色性,因而选用灰色聚类法进行评价是合理可行的。采用层次分析法确定了评价指标及指标权重,建立起了勘查潜力评价体系,对霍西盆地带进行了煤层气资源勘查潜力评价工作。评价结果显示,霍西盆地北部地区勘查潜力以良级为主,局部地区为优级,适宜进行煤层气的勘探开发工作;而南部大部分地区评价结果以可级和差级为主,勘查潜力较差,建议暂不进行开发。
At present, the Huoxi Basin has not yet conducted an effective resource exploration potential evaluation, research work is imminent. Gray clustering method is suitable for the object with definite epitaxy and ambiguous intension. It is reasonable and feasible to use gray clustering method to evaluate because there are few data and incomplete data in Huoxi Basin, and the evaluation of exploration potential has many gray characters. Analytic Hierarchy Process (AHP) was used to determine the evaluation index and index weight, established the evaluation system of exploration potential, and evaluated the potential of CBM resources exploration in the Huoxi Basin. The evaluation results show that the potential exploration potential in the northern part of the Huoxi Basin is dominated by good grades and some areas are excellent ones, which are suitable for exploration and development of coalbed methane. However, the evaluation results in most parts of the southern area are dominated by grade and difference, and exploration potential Poor, it is recommended not to be developed.
