煤层气资源勘探主要是利用测井技术识别和定位煤层气储层,以便进一步求取相应的地质参数。在非常规天然气(页岩气、致密气、煤层气)资源中,由于煤层气藏的裂缝和孔隙并存,具有很强的非均质性,这种储层特征的独特性,使得在煤层气勘探开发中利用常规测井评价在资料采集、基础理论和解决方法、三维储层精细描述上均存在局限性,现行的测井新技术如阵列声波测井等虽在煤层气储层评价中有很大技术优势,但受各方面限制,不够完善,仍需发展。结合认识展望了测井技术在煤层气勘探开发中应用中的发展前景。
CBM resources exploration mainly uses logging technology to identify and locate CBM reservoirs in order to further obtain the corresponding geological parameters. In unconventional natural gas (shale gas, tight gas and coalbed methane) resources, due to the coexistence of cracks and pores in coalbed methane reservoirs, the uniqueness of the reservoir characteristics makes it possible for coalbed methane There are some limitations in data acquisition, basic theories and solutions, and precise description of 3D reservoirs by using conventional well logging evaluation in exploration and development. Although existing logging new technologies such as array acoustic logging are used in CBM reservoir evaluation Great technical advantages, but restricted by all aspects, not perfect enough, still need to develop. Combined with the knowledge of prospects of the logging technology in the exploration and development of coalbed methane development prospects.
