灰色信息系统

  grey information system
     An attribute reduction of discernibility matrix was proposed to do attribute reduction of grey information system efficiently.
     为有效处理灰色信息系统的属性约简问题,将粗糙集理论中有关属性约简的方法运用到灰色信息系统中,提出了一种基于容差关系的辨识矩阵属性约简法.
短句来源
     Interval values were used directly to define the compatibility relation based on the compatibility relation on the closeness degree. When there is not enough information to define a whitening function for grey numbers,it is more impersonal and efficient to do attribute reduction of grey information system in this way.
     这种方法并不对灰数进行白化,而是直接利用灰数的区间覆盖性定义一个基于贴近度的容差关系,并根据这个容差关系建立一个辨识矩阵对属性进行约简,避免了当灰数的取值分布信息缺乏时对灰数进行白化的主观性,是一种较为客观有效的灰色信息系统的属性约简法.

An approach for reservoir evaluation in Chengdao Oilfield using logging multiparameter technique and grey scale theory is presented in the paper. It begins with a calculation step for the evaluation index of each formation based on log data, which is then correlated with strip log,geological data and data from potential test to statistically determine the criterion for reservoir evaluation and the weight for each index. In this way, the cigenvalue of each scale in a grey system is determined and presently employed to whiten the grey system, based on which the prediction for stratigraphic lithology, reservoir parameters, and the hydrocarbon potential is able to be brought about. A program written for the above method has been applied to the data from segments about 4700m in total in 10 odd wells in Chengdao Oilfield. The result is shown to match the core data, the data from potential test, and geological analyses on the whole. Everything regarding the approach is detailed in the paper.

本文利用测井多参数及其灰色系统理论,研究埕岛油田储层评价的方法、技术及应用。它采用测井资料,计算和分析地层评价参数,与岩芯录井剖面、试油及地质资料进行对比,统计确定出储层评价的标准和权值,即确定灰色信息系统中每个灰数的特征值,建立起储层综合评价的灰色理论处理方法。然后,利用特征值参数去白化灰色系统,实现地层岩性、储层参数、物性、含油气性评价和预测。采用本方法编制的程序,在胜利埕岛油田10多口井中实际应用,处理井段4700余米,总体上与区内钻井取芯、试油和地质分析趋于一致。文中介绍了这一分析方法和程序的具体处理过程及应用效果。

Based on the idea that mineral resources system is a kind of grey system and geophysical prospecting information is a kind of grey system of information, a new inversive method combining grey relation with orthogonal test for gravitational inverse problem is discussed. The inversive result of remained gravity anomaly around the drilling well ZKY1 at Xiangshan in Xinjiang conforms with the Cu-Ni deposit geological data provided by the geological team. The method, which needs only few conditions for aim function,...

The inversive result of remained gravity anomaly around the drilling well ZKY1 at Xiangshan in Xinjiang conforms with the Cu-Ni deposit geological data provided by the geological team. The method, which needs only few conditions for aim function, can also be used for inversion caculation of magnetic prospecting and electrical prospecting.
