| 摘 要： | 塔中北斜坡下奥陶统鹰山组受热液改造强烈,来源于地壳深部富含CO2和H2S的热液流体沿断裂、不整合面等发生运移,并对其流经的碳酸盐岩围岩发生溶蚀及白云岩化,形成孔洞缝组合,极大地改善了储层的物性.热液岩溶识别标志为岩石热褪色、非选择性溶蚀、缝洞充填典型热液矿物、“树状扩散”、“层状叠合”的地震反射等特征.

| Abstract: | The Yingshan formation,Lower-Ordovician of North Slope of Tazhong is strongly reformed by hydrothermal solution.Hydrothermal fluids from the deep crust,containing much CO2and H2S migrates along the fault and unconformity plane,corrodes and dolomizes the Carbonate rock flowing by.As a result,the assemblage of pores,holes and fractures is formed and the reservoir is greatly improved.Identification marks of hydrothermal karst are the rock heat bleaching,non-selective corrosion,fracture caves infilling of typical hydrothermal mineral and seismic reflection features of "tree-proliferation","layered composite",etc. |
