Abstract
Disclosed is a method for optimizing multi-cycle pressure-separated water injection in an oilfield based on an improved butterfly algorithm. The method includes: S: obtaining basic data of a target water injection pipeline network; S: constructing an objective function for a water injection scheme optimization model considering multi-cycle pressure-separated water injection; S: establishing constraints to construct the water injection scheme optimization model considering multi-cycle pressure-separated water injection; and S: solving the water injection scheme optimization model considering multi-cycle pressure-separated water injection using the improved butterfly algorithm to generate a multi-cycle pressure-separated water injection optimization scheme.
