山西省深部煤系“三气”资源勘探开发进展及研究
|
摘要
山西省赋存有丰富的煤系"三气"资源,其煤层气开发在国内最先取得商业性突破。但是随着地质勘查工作逐渐向深部发展,近年来单纯煤层气开发逐年减少,而开始关注深部煤系"三气"的共探共采。基于我局近年来开展的煤系"三气"相关勘查研究工作,分析了山西省海陆过渡相煤系"三气"的成藏地质条件及石炭-二叠系煤层气、页岩气和致密砂岩气的赋存特征。针对山西省深部煤系"三气"勘探开发主要存在问题,结合煤系"三气"的研究现状,提出了山西省煤系非常规天然气资源勘查开发的研究和发展方向。研究表明,山西省石炭-二叠系发育了多套煤系"三气"共生组合岩系,"三气"资源潜力大,突破煤系"三气"共探共采关键技术是其规模性发展的基础。
Shanxi Province possesses abundant coal measures"triple-gas"resources,the commercial breakthrough of its CBM exploitation is the first in the country. But along with the geological exploration gradually deepening,simple CBM exploitation has been decreased year after year. Thus the co-exploration and co-exploitation of deep part coal measures"triple-gas"have been turned attention to. Based on our bureau carried out coal measures"triple-gas"relevant exploration research works in recent years,have analyzed transitional marine-terrestrial facies coal measures "triple-gas"reservoiring geological condition and Permo-Carboniferous CBM,shale gas and tight sandstone gas hosting features in the province. In allusion to main issues in deep part coal measures"triple-gas"exploration and exploitation,combined with research status,put forward unconventional natural gas exploration and exploitation research and development orientation. The study has shown that in the Shanxi Province Permo-Carboniferous strata have developed many sets of coal measures"triple-gas"paragenetic association rock series with large resource potential,the breakthrough of co-exploration and co-exploitation key technologies is the basis of coal measures"triple-gas"large-scale development.
