Method and system for quickly identifying caves and cracks in reservoir

The invention provides a rapid identification method and system for caves and cracks in a reservoir, and belongs to the field of oil exploration and development. According to the method, a double logarithmic plate is obtained by using pressure data and yield data collected by a pressure meter and a flow meter, and caves and cracks in the reservoir are identified by using the double logarithmic plate. According to the method, a production data analysis model of the oil and gas reservoir containing the caves and the fractures is established, the typical chart for identifying the caves is drawn, and the caves and the fractures in the reservoir can be rapidly identified. According to the method, the production data analysis technology is adopted to identify the existence and communication states of the caves and the cracks, the caves directly communicated with the well can be identified, and the caves not communicated with the well can also be identified. The method plays an important role in guaranteeing efficie
