本文根据二维信息分配概念及模糊近似推论公式,归纳出便于野外实际应用,精度较好,适应各种测井参数进行油气评价的数学模型。这种方法的核心是利用二维信息分配建立模糊关系矩阵。显然,这种方法简便易行,特别适合复杂储集层油气评价的定量研究。在华北油田的实际应用中,证明这种方法达到足够的精度,其中尤以晋45断块解释结果与试油结论吻合一致。
Based on the concept of two-dimensional information distribution and the fuzzy approximate deduction formula, this paper induces a mathematical model which can be used in the field and has good precision and can adapt to various logging parameters for oil and gas evaluation. The core of this method is the use of two-dimensional information distribution to establish fuzzy relation matrix. Obviously, this method is simple and easy to use, especially suitable for the quantitative study of hydrocarbon evaluation of complex reservoirs. In the practical application of Huabei Oilfield, it is proved that this method has enough accuracy, especially the interpretation result of Jin 45 fault block agrees with the conclusion of oil testing.
