The Research And Application Of Hydraulic Fracturing Proppant Index Method

Ma18-Aihu1 wellblock is characterized by low porosity low permeability reservoir,medium high stress sensitivity,and the main means of production is made by hydraulic fracturing single high flow conductivity of fracture.In the evaluation stage,the fracturing scale increasing,but the effect is not obvious to increase production,the main reason is the insufficient fracture parameters optimization.The existing fracture parameters optimization methods are mainly the intensity of sand,experience chart method,software simulation and proppant index method.Conventional proppant index method does not consider the stress sensitivity of reservoir permeability.In order to guarantee the fracturing effect of long-term,also need to consider the reservoir permeability pressure sensitive effect on fracture parameters optimization.By comparing,proppant index method considering the effect of pressure sensitive in line with the actual,gives the best fracture parameters.This paper uses the improved proppant index method of 606 well S1 layer for fracture parameters optimization.and adopted the PT quasi three dimensional fracturing design software for hydraulic fracturing simulation.And Get sand quantity and construction such as pump injection program data providing reference for the hydraulic fracturing.
