Abstract

The study of dolomite texture not only indicates the origin of the dolomites but controls the quality of dolomite reservoirs significantly.The main objectives of this paper are to investigate the differences of the dolomite reservoirs with distinct textures and the relationship between dolomite texture and  reservoir development of the Cambrian-Ordovician carbonate rocks in central Tarim Basin,based on observation of core,thin-section and SEM,combined with the analyses of petrophysical properties.The results show that:(1)Dolomite texture can be used to predict the reservoir quality due to the strong interdependency between petrophysical properties of the reservoir and dolomite texture,the reservoir qulity of the fine-crystalline.Planar-e(euhedral) dolomite is the best of all the dolomite reservoirs,and the very-fine to fine crystalline planar-s(subhedral) dolomite reservoir is mediate,but the medium to coarse crystalline,non-planar-a(anhedral) dolomite and precursor lithologic fabric preserved dolomite are poor in porostiy;(2) Dolomite texture also affects porosity type.With the shape of dolomite crystal changing from planar-e to non-planar-a,the porosity of dolomite reservoir transforms intercrystalline pore to vug and fracture porosity;(3)The formation and modification process of dolomite reservoir are controlled by dolomite texture,resulting in the shortage of cave porosity and abundance of thin-bedded,porous intervals with intercrystalline/vug porosity in the dolomite reservoirs.
