新疆中低煤阶煤层气勘探开发技术难点及发展方向

Difficulties and Development Direction of Medium and Low-rank Coalbed Methane Industry in Xinjiang Region

新疆煤层气资源丰富,已初步实现产业化,但仍存在地质条件复杂、游离气评价手段缺乏、有利区评价难度大、工程技术与地质条件的匹配性研究不足等难题。为促进新疆煤层气产业发展,文章指明煤层气产业发展需要重点关注四大方面:煤系气综合勘探开发、深部煤层气勘探开发、煤层气田增产与提高采收率技术、“煤层气开发-煤炭地下气化-碳存储”滚动作业模式。

Xinjiang is rich in coalbed methane resources,ad has achieved preliminary industrialization.However,there are still some technical challenges such as complicated geological conditions,lack of effective methods for free gas evaluation,difficulties in evaluating favorable areas,and insufficient research on the matching of engineering technology with geological conditions.To promote the development of the coalbed methane industry in Xinjiang,this paper points out four directions that should be paid attention to during the development of coalbed methane industry:integrated exploration and development of coal measure gas,exploration and development of deep coalbed methane,technology for increasing production and recovery rate in coalbed methane field,and a cyclic operation mode of coalbed methane developmentcoal underground gasification-carbon storage.
