煤层气的主要成份是甲烷,是一种温室气体,如果直接排放到大气中,就会造成生态破坏。同时,煤层气也可以与天然气混输混用,是一种洁净的优质能源。我国的煤层气资源丰富,又具有煤层气储层低含气饱和度、低渗透率以及低压力的特性,因而,对煤层气勘探开发技术的研究具有十分重要的意义。本文通过对我国煤层气勘探开发技术的现状进行分析,探讨了勘探开发煤层气需要解决的技术难题,并针对加强煤层气的勘探开采提出了一些看法和建议,希望对今后煤层气的勘探开发具有参考价值。
The main component of CBM is methane, which is a type of greenhouse gas that can cause ecological damage if it is directly discharged into the atmosphere. At the same time, CBM can also be used mixed with natural gas, which is a clean and high quality energy source. China has rich coalbed methane resources and low gas saturation, low permeability and low pressure characteristics of coalbed methane reservoirs. Therefore, it is of great significance to study CBM exploration and development technologies. Based on the analysis of the status quo of coalbed methane exploration and development technology in China, this paper discusses the technical problems to be solved in the exploration and development of coalbed methane and puts forward some suggestions and suggestions for strengthening exploration and production of coalbed methane. It is hoped that coalbed methane exploration and development in the future will have Reference value.
