摘要
鄂尔多斯盆地奥陶系古风化壳在中—深埋藏阶段 ,具有压释水岩溶发育的水文地质环境。本文通过压释水岩溶形成条件、发育特征及地球化学标志的分析研究 ,进一步揭示了压释水岩溶与天然气生成、运聚和成藏的关系 。
WT5BZ]There was a hydrogeological environment in which compaction released water karst(“CRW karst”) was developed in Ordovician weathering crust of Ordos basin at the mid to deep buried stage. Through analyses of the forming conditions, development characteristics and geochemical signature of the CRW karst, this paper reveals the relationship between the CRW karst and natural gas generation, migration, accumulation, and formation of gas reservoirs, developing new thoughts for gas exploration in those areas where paleokarst developed.
