时频电磁多属性图像融合预测油气技术及应用

TFEM multi-attribute image fusion hydrocarbon prediction technique and its application

时频电磁法是一种时间域和频率域联合电磁勘探方法,在油气勘探开发中应用广泛。时频电磁经过资料采集、处理可以得到多个属性参数信息,从不同侧面反映地下介质的结构特征和含油气性。为了提高时频电磁预测含油气性的准确性,提出采用RGB、HSL色彩模型,通过对时频电磁的几个主要属性参数进行融合处理和显示,可以使反映综合油气参数的"亮点"指示含油气最有利区,以提高解释结果的可靠性,形成了时频电磁多属性融合图像预测油气技术。经塔里木盆地某地区的实际应用,证明该技术实用、有效。

The TFEM method has been widely applied to oil and gas exploration since it was introduced.Through comprehensive interpretation,the geological structure and hydrocarbon condition of subsurface can be well predicted using multi attribute information acquired from TFEM data.For the purpose of improving the accuracy and the reliability of prediction,the TFEM multi-attribute image fusion prediction technique has been developed,which uses"bright spot"from multi-attributes image fusion display based on RGB and HSL color model to indicate most potential oil and gas bearing area.This technique has been proved effective by application in several regions.
