METHOD FOR DEVISING A PLAN FOR HYDRAULIC FRACTURING AND METHOD FOR HYDRAULIC FRACTURING

摘要

The method being proposed makes it possible to optimize a plan (design) for hydraulic fracturing taking into account two-dimensional modeling of transfer processes in a hydraulic fracturing fracture. Devising a plan for hydraulic fracturing in a well bore comprises the following stages: producing data on hydraulic fracturing operations, comprising a plan for pumping in proppant and a plan for pumping in various types of fibres; constructing a degradation matrix for the various types of fibres; devising possible variants of the hydraulic fracturing operation in accordance with the type of fibre and the pumping-in plan. A method for hydraulic fracturing is also proposed, which comprises devising a plan for hydraulic fracturing in a well bore, and also preparing a fracturing fluid containing a carrier fluid, proppant, additives and fibres, and pumping the fracturing fluid into a formation via the well bore in accordance with a selected (optimum) variant of the hydraulic fracturing operation.
