摘　　要：井位部署的合理性直接决定着煤层气资源勘查及后续开发工作的成败。基于煤矿区煤层气资源勘查工作的特点,探讨了勘查井井位部署的原则与方法,并结合红阳煤田徐往子井田煤层气资源预探优化布井实例,提出了先圈定"单因素有利区",进而通过"叠合法"圈定"多因素综合靶区",最终根据靶区地面情况确定勘查井井位的优化布井流程。Rational layout of well site determines directly the success of pmspection and follow - up development work of CBM resources in the mine field. Based on the characteristics of the CBM resources pmspeeting work in the mining area the paper discusses the principles and methods for choosing the site of prospecting wells. Taking the optimal pattern of prospecting wells for pre-prospection of CBM resources in Xuwangzi mine field in Hongyang coalfiled as an example, the authors propose an optimal flow-sheet for determining the site of prospecting wells, i. e. first to delineate ＂the single factor favorable area＂ ; and then to delineate ＂the multi- factor composite target area＂ by using ＂method of superposition＂ ; and finally, to determine the flow-sheet for the optimizing the well pattern based on the surface conditions of the target area.
