将油层评价作为一个包含已知因素和未知因素的灰色过程,采用灰色信息系统中每一个灰数的统计值,建立多参数油层评价的灰色量自动分析数学模型,并应用该模型进行油层评价。作者阐述了利用灰色油层判别方法划分地层有效厚度的原理、方法,结合其在文东油田的应用,证实了与人工分层结果符合率较好。

Reservoir evaluation being as a grey process including known and unknown factors , the automatic analytic mathmatic model to evaluate reservoirs with multiparameters by statistical data of each grey number in grey information system is built up. The mechanism , method of grey reservior system to identify the effective thickness of the formation and its application in Wendong Oilfield are also discussed. It is identified that it’s coefficient is higher than artifical layering.
