【 摘 要 】

Starting from the basic theory of variogram, the influence degree of data analysis on the result of attribute distribution calculation is given by parameter influence experiment. Combined with the practice of geological modeling, the "false fitting" phenomenon of the data analysis curve is found, and a new method of data analysis technology is put forward at the same time by using the theory of variation function. The technical method designs the parameter adjustment process, gives the parameter setting range, and realizes the transformation from experience to quantization of data analysis. In the actual modeling of an oilfield, the distribution of the one or two and three types of reservoir properties has been accurately characterized, and the accuracy of the attribute model has been greatly improved.
