Among used machine learning methods, the gradient descent method is widely used to train various classifiers, such as Back-propagation neural network and linear text classifier. However, the gradient descent method is easily trapped into a local minimum and slowly converges. Thus, this study presents a gradient forecasting search method based on prediction methods to enhance the performance of the gradient descent method in order to develop a more efficient and precise machine learning method for Web mining.However, a prediction method with few sample data items and precise forecasting ability is a key issue to the gradient forecasting search method. Applying statistic-based prediction methods to implement GFSM is unsuitable because they require a large number of data items to model a prediction model. In the contrast with statistic-based prediction methods, GM(1,1) grey prediction model does not need a large number of data items to build a prediction model, and it has low computational load. However, the original GM(1,1) grey prediction model uses a mathematical hypothesis and approximation to transform a continuous differential equation into a discrete difference equation in order to model a forecasting model.

其中梯度法是一个最常被使用来实现机器学习的方法之一，然而梯度法具有学习速度慢以及容易陷入局部最佳解的缺点，因此，本研究提出一个梯度预测搜寻法则(gradient forecasting search method， GFSM)来改善传统梯度法的缺点，用来提升一些以梯度学习法则为基础的分类器在资讯探勘上的效率与正确性；而一个所需资料量少、计算复杂度低且精确的预测模型是梯度预测搜寻法能否有效进行最佳解搜寻之关键因素，传统统计为基础之预测方法的缺点是需要较大量的数据进行预测，因此计算复杂度高，灰色预测模型具有建模资料少且计算复杂度低等优点，然而灰色预测理论以连续之微分方程式为基础，并且透过一些数学上的假设与近似，将连续之微分方程式转换成离散之差分方程式来对离散型资料进行建模及预测，这样的作法不尽合理，且缺乏数学理论上的完备性，因为在转换过程中已经造成建模上的误差，且建模过程仅考虑相邻的两个资料点关系，无法正确反应数列未来的变化趋势。

According to gathering plentiful relative datum of of Xuer section of Yazihe structure and seismic、 well logging、 surveys、 core ect during the exploitation and exploration,the research starts with analise of slice data、 core observation and core specimens,then combines with coordination、 analyse、 concluding and the former research result.The article recognizes the tectonic feature of Xuer section of Yazihe structure and it"s tectonic evolution,analyzes the distributing feature of oik、 gas、 water、 their dominated factor、 the pressure feature of gas reservoir and especially the conservative condition of Xuer gas reservoir.At the same time,the article acquaintances the depositional feature and sedimentary environment and discusses the main genesis typeof reservoir sandstone.By analyzing the physical feature and physical relation of reservoir rock, the article first classifies and evaluates the reservoir rock simply ,then concludes it"s feature of reservoir and permeability. According to detailed core observation and fracture explanation in well logging ,the article uses single well fracture indentifying and evaluation to confirm the section where the fracture growths,putting emphases on the method to get parameter of fracture,such as fracture width and fracture porosity.Finally,combining with the principal curvature for tectonics deformation the article predicts the plane fracture of reservoir and weave the general evaluation map of crack fracture growth.
