储层产能预测文献，对于研究利用测井进行产能预测有帮助！(Prediction of Specific Productivity Index for Sihapas Formation in Uncored Wells of Minas Field Using Limited Available Core and Log Data)

说明：  Optics聚类算法 OPTICS没有显示地产生一个数据集合簇，它为自动和交互地聚类分析计算一个簇次序。这个次序代表了数据基于密度地聚类结构。它包含地信息，等同于从一个宽广地参数设置范围所获得的基于密度的聚类(Optics do not show clustering algorithm OPTICS to produce a collection of data clusters, it is automatically and interactively computing cluster analysis a cluster order. This order represents the data to cluster based on the density structure. It contains in information from a broadly equivalent range of parameters obtained by density-based clustering)

晶格波尔兹曼方法，D2Q9的Matlab程序.(Lattice Boltzmann method, D2Q9 procedures)

the structure of the DG-FEM is very similar to that of the finite element method (FEM), there are several fundamental differences. In particular, the mass matrix is local rather than global and thus can be inverted at very little cost, yielding a semidiscrete scheme that is explicit. Furthermore, by carefully designing the numerical flux to reflect the underlying dynamics, one has more flexibility than in the classic FEM to ensure stability for wavedominated problems. Compared with the FVM, the DG-FEM overcomes the key limitation on achieving high-order accuracy on general grids by enabling this through the local element-based basis

T矩阵方法的FORTRAN环境下的程序，希望对大家有帮助！(T matrix method program FORTRAN environment, we want to help!)

程序提示用户输入两个数,然后它将输出这两个数字的和、差、积、商、以及余数，分十进制和十六进制两种格式 (The program prompts the user to enter two numbers, then it will be the output of these two numbers and difference, product, quotient, and the remainder, and decimal and hexadecimal two formats)

test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as the system output signal. signal_analyzer.m first test1.txt data read workspace, and then proceed to FFT, analysis of the two signals in the frequency, the output for input amplitude attenuation (db), the output of the input phase difference.)
