Optimization Design Of Fracturing Parameters In Chang6Reservoir Of Ganguyi Oilfield

This paper obtains Chang6oil layer rock mechanical parameters such as rock elasticmodulus, Poisson’s ratio, anelasticity through the rock mechanics experiment. The crustalstress size, the direction and the stress section plane has been determined, according to thewell logging data. It is considered that the minimum principal stress of Ganguyi oilfield isdirection of vertical stress and hydraulic fracture morphology is horizontal seam.At the same time, the reservoir of integral fracturing optimization model has beenestablished, and the solution has been carried out. On this basis, this paper has studiedintegral fracturing fracture parameters optimization for three different blocks. Aimed at5462well group, according to the well group without injection wells, injection wells and wells butnot fracturing and fracturing three scenarios were simulated. Results indicate that the effect isbetter when the group has injection wells and injection wells fracturing.Using the results from numerical simulation and optimization carries on the hydraulicfracturing construction, the oil wells on the daily oil production and cumulative oilproduction relative to compare wells in production, there is a significant increase, andcumulative increased oil volume increased by up to94.3%, the smallest production besidesthe8126-6well in25%above. The field production data indicate that the yield-increasingeffect apparently after hydraulic fracturing.
