钻井风险评价方法与模型建立

The Building of Evaluation Method and Mathematical Mode of Drilling Risk

文章提出了钻井风险的多因素多层次综合评价方法 ,以层次分析法建模 ,并实现了该模型的求解。系统研究了层次分析法 ,为建模提供了依据。所建立的模型阐明了多因素多层次与风险的关系。通过对实例的分析 ,说明该方法可行。

In this paper the mode of risk evaluation is set up based on the multi-fator and multi-hierarchical synthetical estimate method,which is formed by hierarchical analytical model and implement the correct model solve. It studies hierarchical analytical method which helps to building modes. At the same time the modal built illustrate the correlation of multi-fators,multi-level and risk. The evaluating method is proved to be feasible though example.
