Abstract: Through comparing the coal bearing basins in Daqing exploration area and those successfully developed in the United States, on the basis of in-depth analysis about the characteristics of CBM resources, this paper put forward the measures for comprehensive utilization of CBM resources in Daqing exploration area: stressing new idea in terms of exploration target selection and promoting five transformations, i.e. òthe orientating of research targets is transformed from coalfield geology to coal-derived gas geology; the method for target selection is transformed from geological results to integrated ones; the selecting of resource types is transformed from CBM to coal-derived gas; the determination of hole pattern is transformed from single well to well group; the evaluation on overall profits is transformed from industrial air stream into commercial valueó, pursuing accurate selection and reasonable implementation of òdessertó CBM resource targets; focusing on new techniques for the implementation of related projects and intensifying five applications, i.e. the technique for òwide-azimuth, wide-band, and high-densityóseismic prediction of coal bed, the multi-way drilling and completion technique, the multi-method technique for comprehensive evaluation of gas layers, the multi-parameter lab analysis technique, and the simple highefficiency fracturing and drainage technique, to satisfy objective evaluation and efficient exploration and mining of CBM resources; laying emphasis on new mechanism for production, operation and management and exploring practice in five aspects, i.e. òlow-cost projects, integrative model, oil and coal combination, foreign cooperation, and operation of small companiesó, so as to maximize the benefits of comprehensive use of CBM resources in an all-round way.
