Classifying Evaluation Method for Proved Reserves of Fuyu Oil Layer in a Certain Area
Download as PDF
This paper puts forward classifying evaluation method for proved reserves of F oil layer in a certain area based on unit division by classifying and evaluating, optimizing and queuing. Firstly, the classification criteria of 11 individual evaluation indexes are established, and then the weight of synthetic evaluation classification are calculated via combining three methods: correlation coefficient method, principal component factor analysis method and analytic hierarchy process (AHP) method. The comprehensive score of each unit is calculated by using the method of comprehensive score weight analysis, and FI and FII with seven blocks in the whole area are divided into three categories according to the characteristics of reservoir development and oil-water distribution.
