Problems solved by technology
However, in carbonate reservoirs with complex secondary pores, due to the irregular storage space and complex network of pores, caves, and fractures, the connectivity of the reservoir is extremely complicated, which leads to the complexity of oil, gas and water production.

Embodiment Construction
[0053]Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
[0054] In the embodiments of the present invention, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three types of relationships, for example, A and / or B, which can mean: A exists alone, A and B exist simultaneously, and B exists independently. A, B can be singular or...

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.
Description
technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to an identification method, device, equipment and storage medium for weakly connected fracture-cavity reservoirs. Background technique [0002] Reservoir connectivity is a major problem in the exploration and development of complex oil and gas reservoirs, and it is also a frontier field of reservoir geology and development geology research. A lot of new progress has been made in the identification of reservoir connectivity through seismic data, drilling data, testing and production performance data, and in the simulation of connectivity. However, in carbonate reservoirs with complex secondary pores, due to the irregular storage space and complex network of pores, caves, and fractures, the connectivity of the reservoir is extremely complicated, which leads to the complexity of oil, gas and water production. . [0003] At present, it is mainly combin...
