Abstract EN
Due to a large number of natural fractures in tight oil reservoir, many complex fracture networks are generated during fracturing operation.
There are five kinds of flow media in the reservoir: “matrix, natural fracture, hydraulic fracture network, perforation hole, and horizontal wellbore”.
How to establish the seepage model of liquid in multiscale medium is a challenging problem.
Firstly, this paper establishes the dual medium seepage model based on source function theory, principle of superposition, and Laplace transformation and then uses the “star-triangle” transform method to establish the transient pressure behavior model in the complex fracture network.
After that, perforating seepage model and variable mass flow in horizontal wellbore were established.
Finally, continuous condition was used to couple the seepage model of dual medium seepage model, transient pressure behavior model in the complex fracture network, perforation seepage model, and the variable mass seepage model in horizontal wellbore, to establish a semianalytical coupled seepage model for horizontal well in tight reservoir.
This paper provides theoretical basis for field application of horizontal well with complex fracture networks.
