Abstract

Abstract: Baode CBM field is located in the north of Hedong Coal field in the northern section of west Shanxi flexure zone, eastern margin of the Ordos Basin and its CBM resources are abundant. The CBM reservoirs in Baode Block are geologically characterized by shallow burial depth, low gas content, frangibility, collapsibility, low mechanical strength, low porosity, extra low permeability and underpressure, so its exploration and development are faced with a series of technological problems, including geological evaluation, well drilling and completion, reservoir stimulation, gas production engineering and surface gathering. To solve these problems, PetroChina Coalbed Methane Co., Ltd. reviewed previous exploration achievements systematically, and then analyzed comprehensively the geological and reservoir characteristics of middle and low rank CBM in the study area based on existing data of various coal fields, e.g. borehole, seismic, drilling, logging, well test and sample assay. It researched the evaluation technology of fine CBM area selection and developed a series of exploration and development technologies suitable for middle and low rank CBM. It also insisted on geology-engineering integration research to break through the bottleneck of CBM exploration and development technologies. Besides, it completed and optimized continuously the technological solutions from the aspects of geophysical exploration, well drilling, fracturing, drainage gas recovery and surface engineering. Thus, the CBM in Baode block is developed efficiently and China's largest middle and low rank CBM field is built up.

Key words: coalbed methane (CBM), Baode block, middle and low rank coal, geology-engineering integration, exploration and development
