辽河油区煤炭地下气化技术分析与实践

在介绍煤炭地下气化技术基本原理的基础上，根据辽河盆地东部凹陷小龙湾地区煤层地质概况．试验区录井、测井、试采成果及预测结果，通过对煤炭地下气化技术的可行性分析，认为该区块煤炭资源丰富，煤层割理发育，孔渗条件较好，具备开展该技术试验的储层条件。对部署的资料井——小M2井进行了施工前的风险及难点分析，通过钻井施工技术实践，进一步落实了该区块的地层构造、煤层分布及延伸情况。获取了煤层实际样本资料（取心），为煤炭分析化验及物理模型提供了数据资料。探索性地总结分析了在煤炭地下气化钻井施工技术中具有一定代表性的问题，并采取了相应的技术措施，为煤炭地下气化技术发展提供了宝贵的研究思路，并积累了现场经验。

Underground Coal Gasification Technology in the Liaohe Oilfield

Based on coal gasification principle,coal bed geology of the Xiaolongwan area located in the east depression in the Liaohe basin, predictions and data from well logging and production tests, reservoir of this area, after feasibility analysis, is considered suitable for underground coal gasification test due to its abundant coal resource,developed coal bed cleap,better porous seepage condition. Necessary data for coal analysis and physical model are obtained from risk and trouble analysis on well XiaoM-2 (an allocated data well), information of formation stratum, coal bed distribution and extension verified by drilling operation, and actual coal samples. Typical problems arise from this operation arc probed and their countermeasures are also brought forward, which provide valuable research directions and field experience for the underground coal gasification technology.
