- 摘要:
- 在当前国际能源供需矛盾日益突出的形势下，煤层气的资源勘探开发备受世界瞩目。对于此类非常规气田的开发人们借鉴常规油气田开发技术并加以改进，探索出开发煤层气的技术。主要概述了国内外煤层气井的压裂技术和排采技术的研究现状，分析存在的问题；对比各技术的优缺点和适用性，提出我国煤层气开发技术需加强的方面，展望未来发展趋势。清洁压裂液研制、二氧化碳泡沫压裂和氮气泡沫压裂技术改善，排采使用装置和排采工作制度改进是目前我国煤层气发展的主要技术突破点。
In current more and more unbalance situation between energy sources supply and demand，development of coalbed methane（CBM） attracts the world?蒺s attention. In such unconventional gas field development，those technologies widely adopted in conventional gas field development are used for reference and improved in order to explore technologies useful for coalbed methane development. Summarized are the fracturing and drainage technologies adopted in coalbed methane development and current status of studies on these technologies，analyzed are problems existing in actual development，compared are advantages and disadvantages of various technologies and their suitability，proposed are the aspects necessary to strengthen in coalbed methane development in China and feasibilities and forecasted is the development tendency. It is point out that development of clean fracture fluids，improvement of carbon dioxide foam fracturing and nitrogen foam fracturing technology and improvement of drainage equipment and drainage working system are important technology breakthrough points in current coalbed methane development in China.
