属性技术在油气检测中的应用
|
摘要
利用地震属性进行油气检测应用较广,通常利用某种地震属性与油气之间的关系去预测储层。理论证明地震波通过含气储层时频谱要发生衰减,因此利用地震资料频谱衰减信息进行含气储层预测,具有一定的可行性。在对测井和地震资料分析基础上,对含气储层处的地震资料频谱衰减进行研究,寻找谱衰减属性预测含气储层的方法,阐明了利用谱衰减属性预测含气储层的机制,并利用该方法计算实际资料,并与已有的地质资料进行了对比分析。
It is a wide application to use seismic attribute to make hydrocarbon detection.We often apply the relation between some seismic attribute and hydrocarbon to forecast reservoir.The theory has been proved that the frequency spectrum will be attenuated when the seismic wave passes gas containing reservoir,so it will be available to use seismic spectrum attenuation to make gas containing reservoir forecasting.Based on the analysis of the information from well logging and seismic,this article makes research on seismic spectrum attenuation of gas containing reservoir,looks for the method to use spectrum attenuation to forecast gas containing reservoir,and illustrates the mechanism which utilizes spectrum attenuation attribute to make gas containing forecasting.We also use this method to calculate the actual data and make comparison and analysis with the geologic information we have got.The results have showed that the method is effective on reservoir forecasting.
