Based on the analysis of core, logging, well logging and test data, five types of carbonate reservoirs are distinguished, including cave, structure fracture, weathered fracture, vugular porosity of bank-facies grainstone and fracture-pore of surface residuum. Reservoir properties and distributing characteristics of the reservoirs are summed up, and the paleo-karst formation mechanism and controlling factors of the cavernous reservoir growth and distributing degree are discussed. The development of three suites of cavernous reservoirs extending 0-250 meters below the unconformity interface is the key to high-yielding and oil and gas sources. Weathered fracture reservoirs focus on the neighborhood of the early Hercynian unconformity interface and above or below the cavernous reservoirs. The growth and distribution of fracture reservoirs have universality, which is well correlated with the growth degree of the cavernous reservoirs. The vulgar porosity reservoir developing on the bank-facies grainstone of the upside Yijianfang Formation is controlled by facies and layers. The growth degree of karst cavernous reservoirs is controlled dominantly by physiognomy and fracture growth degree. The most developed area of karstification is the superposed positions of the gentle slope of karst-buried hills and the axis of the Akekule heave.
