According to different methods treating post-pouring rebar,it discusses influencing of installation of post-pouring strip to anti-crack,analyzes influencing to binding force from area of continuous rebar、width of post-pouring strip、position of resultant force and inverted value,it indicates binding tensile force is smaller,the effect of anti-crack is well.

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;
