Test results illustrate its good practicability to solve oil well fracture effect forecast problem.

Prediction of fracturing effect using feed-forward neural network,;

In order to evaluate the fracturing effect accurately, this paper systematically formulates the evaluation foundation of the low-permeability fracturing well at present and three practical evaluation method are given by analysis of fracturing effect using actual well-testing data, basing on the well testing interpretation theory of fracture wells.

Application of data mining to postfracture response evaluation in gas field;

The system consists of an analysis module for dominant factors,an optimization module for technology parameters and a forecast module for grinding effects,by which the optimizing selection of machining parameters and the ground effect forecast of diamond milling cutters in WEDM grinding can be carried out.
