摘要:
热液活动对塔东地区白云岩储集层的形成起着重要作用。综合应用岩石薄片显微镜鉴定、阴极发光分析、碳氧同位素分析、微量元素分析、稀土元素分析等技术,研究了热液地质作用对塔东地区寒武系白云岩储集层的影响,建立了热液作用的期次及其岩石矿物学和地球化学识别标志。对寒武系碳酸盐岩储集层具有改造意义的热液作用有两期,Ⅰ期热液作用发生在中-晚奥陶世,在寒武系白云岩中形成裂缝,而对泥灰岩层段改造较弱或未改造;Ⅱ期热液作用发生在二叠纪末,表现为研究区内广泛的热液溶蚀作用,形成寒武系重要的溶蚀缝洞型白云岩储集层。
Abstract:
Hydrothermal activity played an important part in the formation of dolostone reservoirs in Tadong area (eastern Tarim basin). By applying the technologies of rock thin section microscopic identification, cathodoluminescence analysis, carbon and oxygen isotope analysis, trace element, rare earth element analysis, etc, the hydrothermal process and formed Cambrian hydrothermal dolostone reservoirs in Tadong area were studied. There are two stages of hydrothermal processes with transformed effect significance on the Cambrian carbonate reservoirs, and corresponding rock mineralogical and geochemical identification marks of the two hydrothermal processes are established. The Stage?Ⅰhydrothermal process took place in the Middle-Late Ordovician, its transformed effect on the Early Cambrian consolidateddolomites was dominated by formation of fractures rather than on the Cambrian microcrystalline limestone, marl and mudstone intervals. The Stage?Ⅱ hydrothermal process took place in late hercynian at the end of Permian, and its transformed effect created wide distribution of hydrothermal dissolution and formed Cambrian important dissolution fractured?vuggy reservoirs in this area
