Embodiment Construction
[0160] Below in conjunction with accompanying drawing, the present invention will be further described:
[0161] This kind of well test interpretation model for analyzing dual-porosity composite reservoirs in fracture-cave series mode is as follows: according to a certain type of reservoir, establish a corresponding physical model, then establish a mathematical model describing the physical model, solve the mathematical model, and finally Get the theoretical curve. Analysis of theoretical curves yields explanatory parameters. The physical model in which is:
[0162] The karst caves are connected by large fractures, and the karst caves and large fractures constitute the fracture-cavity model as a series of fracture-cave models. The parameters such as the volume and storage capacity of the karst caves are different, and the parameters such as the seepage cross-sectional area, length, and flow capacity of the large fractures are different; The surrounding area is a two-zone com...
