Application on Expert System to Predict the Effect of Fracturing Measures

Abstract:

Hydraulic fracturing is one of the main stimulations, however, it is effected by various factors. This paper considers the influence of net thickness, permeability, flow pressure, water cut, injector—producer distance, cumulative injection-production ratio, sand input intensity, pad fluid volume, sand ratio. Applying the expert system to establish the predictive knowledge base, dividing various effect factors into four grades, and giving the different membership functions according to different grade. The 76% prediction results of established expert system are the same as actual results, and 20.5% are close to the actual results. The results show that the established expert system has the guidance action on the layer selection of fracturing and the fracturing design.
