The invention provides a
fissure-
cave type
carbonate-reservoir reservoir body modeling method, and belongs to the field of
carbonate reservoir exploitation geology. The method comprises the steps of (1) distinguishing
karst cave reservoir body development segment in a single well; (2) building
karst zone models along the vertical direction, building ancient
landform unit distribution models in a plane; (3) respectively imitating three-dimensional distribution of the
karst cave reservoir body in different karst zones and different ancient
landform units, obtaining a three-dimensional
distribution model of the karst cave reservoir body of a modeling target stratum; (4) counting development occurrence of a
fissure reservoir body and single-well
fissure development density; and (5) under control of a fault, building a three-dimensional discrete
distribution model of the fissure reservoir body. According to the fissure-cave type
carbonate-reservoir reservoir body modeling method, accuracy of the class of
reservoir modeling is improved, a true condition of the reservoir is approached in a more objective mode, and important practical significance is provided for exploitation of the reservoir.
