摘要
定量交会技术在油气勘探中应用广泛,在储层流体识别中也起到了非常重要的作用。笔者介绍了多参数优选的方法,经计算得到敏感性较高的参数,在此基础上进行流体属性敏感性分析,避免多参数选择的多解性和不确定性。以Castagna和Smith发布的在全球范围测量的25个数据集为模型,用优选的参数进行三维交会分析,对储层的识别效果很好。
The quantitative intersection technique is widely used in oil and gas exploration and also plays an important role in the recognition of reservoir fluid.This paper deals with the multi-parameter optimization method.Through calculation,highly-sensitive parameters can be obtained and,on such a basis,fluid attribute sensitivity is analyzed,thus avoiding multi-interpretation and uncertainty in multi-parameter choice.With the global survey-based 25-data set published by Castagna and Smith as the model,the authors made 3D intersection analysis with optimized parameters,and attained good result in reservoir recognition.
