Abstract


Casing damage is one of the main factors influencing oil production, and determined the main factors which lead to casing damage is the premise to develop effective prevention and control measures of casing damage. The relationship between various factors of casing damage is complicated, and it is difficult to determine the main factors influenced the casing damage applying for conventional theoretical analysis and quantitative calculation. In this paper, the main factors influenced casing damage is evaluated by the method of combination fuzzy comprehensive evaluation and grey relational grade analysis. Firstly, this article analyzed factors causing casing damage, and then evaluated 22 wells of Daqing oilfield which is located in the west block of the Southern District fault. Comparing the evaluation and the actual results, the accuracy rate of this model is 86.3%, and showing that the evaluation results are accurate and reliable.
Key words: Casing damage; Fuzzy comprehensive evaluation; Grey relational grade; Effect evaluation
