Fuzzy Pattern Recognition In The Fine Reservoir Evaluation

Gathering Fuzzy technique and Model-identifying technique to processing research, Fuzzy model-identifying technique, a intersecting science, has been come out, which has become hoto In this thesis, based on deeply researching the Fuzzy unit-identifying and complete analysis on data of measuring well of the Chandqing Wushenqi District, the method of constructing self-adapting multi-dimension non-liner subjection degree function has been created without precedentoBased on the extraction of routine measuring well character parameters, and for adopting self-adapting method to carry through character compression, the model has been improved the performance and enhanced the convergence speed and sorted precision of the algorithm oThe relation of measuring well information and the oiliness & gassiness of sandstones is fuzzy?In the thesis, the law of Max Subjection Degree has been studied and improved, and proved preferable effect in the practical application ?The algorithm and software of self-adapting have been developed successfully in the thesis, which is the procession of comparing the corrective rations of returning estimation ,then adjusting the parameters, finally training the model into the best effectively model?The capability of the trained model can been qualified through comparing the result of the trained model identifying and the result in the facto In the thesis, the trained model is applied to presuming the unknown sandstones and acquire the wishing effect, and the presuming maps are drawn in the forth chapter in the thesis oIn order to the convenience of the operation, in the fifth chapter of the thesis the Fuzzy model-identifying software system has been developed, which makes the algorithm, the query of the data, and showing the presuming maps into the fact, and which provides scientific and reliable decisive reference resource for the more estimation o It is very valuable o...
