Progress of coalbed methane exploration and development in China during the 13th Five-Year Plan period and the next exploration direction

  • 摘要: 基于我国煤层气勘探开发项目、煤层气田生产现状以及科研技术成果的调研资料,分析了煤层气田稳产、提产综合治理技术措施,深层煤层气取得勘探突破的地质条件和潜力,支撑上述两方面进展的煤层气水平井技术以及相配套的井网优化、排采技术。结果认为,我国煤层气田稳产、低产井提产综合治理最有效的技术措施有四类,包括增加新层、调整开发方案扩大产量规模、水平井嵌入加密井网、老井增产改造技术。提出了“煤层气水平井+技术体系”概念,即水平井钻完井+套管分段压裂+无杆泵排采技术组合体系,强调在井网优化部署、钻完井、压裂工艺和排采技术设备等各个环节的相互匹配。界定了深层煤层气涵义,深层煤储层一般存在游离气,临界深度受地层温度梯度和压力影响。指出深层煤层气、低阶煤煤层气是下一步煤层气勘探重点领域和方向。
