Abstract

The embodiment of the invention provides a weakly connected fracture-vug type reservoir identification method and device, an apparatus and a storage medium, and the method comprises the steps of determining the basic features of various types of reservoirs in fracture-vug type reservoirs, wherein the various types of reservoirs comprise non-connected fracture-vug type reservoirs and connected fracture-vug type reservoirs; obtaining the basic features of a target reservoir; matching the basic features of the target reservoir with the basic features of the non-connected fracture-vug type reservoir and the basic features of the connected fracture-vug type reservoir; and when the basic features of the target reservoir are not matched with the basic features of the non-connected fracture-vug type reservoir and the basic features of the connected fracture-vug type reservoir, determining the type of the target reservoir as a weakly connected fracture-vug type reservoir. The method is simple and easy to implement, can be widely applied according to the actual data, and can identify the carbonate rock weakly-connected fracture-vug type reservoir, so that the evaluation and development of the complex fracture-vug type reservoirs can be effectively guided.
