油气勘探风险评价方法与评价模型

Evaluation Method and Model of Risks in Oil-Gas Exploration

油气勘探风险评价方法包括石油地质风险和技术经济风险。要将千变万化的石油地质条件进行比较评价 ,必须通过一个模型进行归一化处理 ,该模型提出了三级因素 ,各级又细化了因素项 ,并提出了各因素项四等评分的标准和权重 ,作为石油地质条件归一化的标准。

The evaluation method of risks in oil-gas exploration involves the evaluations of risks in petroleum geology and technological economy.For comparing and evaluating the protean petroleum geological conditions,it is necessary to give a normalized treatment with a model.This model sets forth three grades of factor and subdivides each grade into several factor items.As the criterion of normalization of petroleum geological conditions,the model also puts forward the standard and weight for grading each factor to four levels.
