摘要
天然气水合物饱和度预测是天然气水合物资源评价的基础,饱和度预测研究有利于了解天然气水合物作为地质灾害和引发全球气候变化所起的作用,同时对了解天然气水合物的成藏规律和指导天然气水合物的勘探开发具有重要的指导意义,因此,准确预测天然气水合物饱和度非常重要。目前电阻率和氯离子浓度异常、氯离子剖面以及声阻抗测井数据均可预测水合物饱和度。
Prediction of gas hydrate saturation is the basis to evaluate gas hydrate resources.This method can help us understand the role of gas hydrate as a geologic hazard in the changes of global climate,and can also help us know the pooling regularities of gas hydrate and explore this energy resources.Therefore,it is very important to correctly predict the hydrate saturation.At present,electric resistance,chloride ion concentration anomaly,chloride ion profile and acoustic impedance logging data can be used to predict the gas hydrate saturation.
