Abstract:
The carbonate rock pores in Taikong uplift have two major types: primary pore controlled by primary fabric and secondary pore contrlled by other factor, a tolal of sixteen kinds. The reservoir spaces include pore, cave and fissure. The physical Characteristics of the reservoirs are affected by the filling state and connecting state of pores. The different type of pores has different contribution to the reservior space. The having more contributions are intercrystalline pore, intercrys talline solution pore, secondary interparticle pore, interbreccia pore, solution fissure and structural crack, but the other types of pore have little effect to reservoir space as they are almost infilled.
