Abstract: In view of specific problems existing in the exploration and evaluation of carbonate rock reservoir in Shanbei exploration region of Zhongyuan Oil Field, with the analyzing results of core pore structure, the paper sets up a new interpretation mcxlel and studies the calculation methods for various reservoir parameters. It overcomes the limitation of preciously determining geological parameters of carbonate rock by normal CRA complex lithology method. It forwards estimation methods of fracture distribution and quantitative interpretation standard of prcxluction formation and tight formation. The paper resolves important technical difficulties for the identification of carbonate rack reservoir,as well as effectively discovering reserves and calculating the reserves.
