摘要
在进行储层描述或油气预测时,吸收系数是一个很重要的参数,它反映岩性的变化具有较高的灵敏度。利用吸收系数并配合速度、振幅和频率等其它地震或非地震信息,进行油藏描述和油气预测有其独特作用和效果,可大大提高储层横向预测解释的精度。本文简述了反演吸收系数的方法原理,重点阐述了吸收系数在SN地区WJ构造储层横向预测中的应用和效果。
The absorption coefficient is a very important parameter in the reservoir description or hydrocarbon prediction. It has a good sensitivity to the variation of lithologies, When performing the reservoir description or hydrocarbon prediction, the absorption coefficient and other information such as velocity,amplitude,and frequency play a uniquc role,greatly improving the accuracy of the resewoir lateral prediction.In the paper, the methodology for the inversion of the absorption coefficient is Sumarized. The emphasis is laid on expounding thc application of the absorption coefficient in the reservoir lateral prediction in the WJ structure of the SN area and its effect.
