Abstract:

During the development of oil and gas field, the analogy method is often used to study the development technology policy and predict the development index for the undeveloped or early stage reservoir. The selection of analogy samples, i.e. similar oil and gas fields, determines the reliability of analogy results. Therefore, gray correlation and geological factor analysis are used to determine the analogy parameters and weights quantitatively on the basis of the essential correlation between analogy parameters and analogy objectives. According to the reservoir type of the studied object, the parameter thresholds are introduced to calculate the similarity of the samples, and the oilfields with high similarity are selected as the reference samples for the technical policy research and index prediction, so as to make the basic conditions of the objective basis of analogy analysis are more reasonable, and further improve the efficiency of screening and the reliability of analogy results.

Key words: grey relation, basic parameters, threshold, similarity, quantitative analogy
