Abstract

The paper introduces the basic principle of grey correlation analysis method and offers its application in the clastic reservoir of Qingdong sag.By adopting this methodology,we can quantitatively evaluate the physical parameters of 9 wells and 21 reservoir units and determine the weight coefficient of evaluation index.Thus,the comprehensive reservoir evaluation in this area is gotten.The result of the application shows as follows: firstly,this method avoids contradictory results and un-uniqueness which often occur when single index is chosen; and the evaluated result is highly consistent with that of onsite well production.Secondly,considering combination of all evaluation parameters involved,the precision of reservoir evaluation can be enhanced by digitizing the single or imprecise treatments and quantifying the evaluation results.Thus the application of grey correlation analysis method to evaluate the reservoir is reasonable and objective.

Key words： Grey correlation analysis; Evaluation index; Reservoir division; Weight coefficient; Reservoir evaluation.
