Carbonate stratigraphy developed in the Sinian,Qigebulake Formation,Tarim Basin,which is mainly composed of carbonate ancient stratum,formed the old geological times.Core observation,thin section analysis and outcrop measurement showed that the petrological type of Qigebulake Formation contains microbial dolomite,grain dolostone,crystalline grain dolostone and hybrid sedimentary rock.The statistics data of 150 thin sections show that microbial dolomite accounted for about 30%,grain dolostone for 25%,crystalline dolostone for 30%,and peperite accounted for 15%.The reservoir space type of Qigebulake Formation contains inter-crystalline pore,inter-granular pore,microbial lattice,solution cavity,and fracture.By collecting and testing porosity and permeability data,it is proposed that microbial dolomite porosity distributed between 2.5% and 3.5%.The grain crystalline dolostone porosity value distributed between 2%-4%,and the biggest can be close to 9%.The bigger the grain size,the greater the permeability and porosity.Tgrain dolostone porosity ranges from 2% to 3.5%,partly up to 7% which is related to inter-granular corrosion cavity reservoir space.On this basis of carbon and oxygen isotope and inclusion data analysis,combined with the sedimentary microfacies,atmospheric fresh water dissolution is the main contributor of reservoir.Burial dissolution and tectonic hydrothermal process for reservoir preservation and transformation also play an important role in reservoir formation.
