Carbonate rock fracture-cavity reservoir reserve correction method

The invention discloses a carbonate rock fracture-cavity reservoir reserve correction method. The method comprises the following steps: establishing a sample well in an effective carbonate rock fracture-cavity reservoir area; obtaining reservoir volume correction coefficient according to the actual mining amount and reservoir parameters of a sample well; and carrying out correction on the reserves in the effective carbonate rock fracture-cavity reservoir area according to the reservoir volume correction coefficient. Therefore, the method solves the problem of low prediction precision of the carbonate rock fracture-cavity reservoir reserves, so that the prediction precision of the carbonate rock fracture-cavity reservoir reserves is improved, risk and cost in the further mining work are reduced, mining investment is allowed to be more accurate, and higher prediction benefit and exploitation benefit can be obtained.
