Abstract
The present invention discloses a method for evaluating fracture connectivity and optimizing fracture parameters based on complex network theory, comprising the following steps: obtaining natural fracture distribution laws and characteristic parameters of the formation based on previous knowledge of natural fractures in the formation and statistical analysis of fractures in the core, and establishing a discrete fracture network model of natural fractures based on the previous step; setting up hydraulic fractures, determining intersection relations in the fracture network and coordinates of intersection points of fractures: converting the actual fracture network into a complex network dual topology diagram based on complex network theory, and calculating evaluative indexes of the complex network to realize the evaluation of fracture network connectivity; changing the hydraulic fracture parameters to get the evaluation indexes of different hydraulic fracture schemes.
