| 摘 要： | 针对稠油蒸汽热采区常见的声波资料异常现象, 根据双相多孔介质声波传播理论及相关实验结果，对于这一特殊的声波测井响应特征进行了解释，认为注入蒸汽的影响导致了纵波速度的低异常及幅度的强衰减, 而使声波测井资料显现出异常高时差值或出现“跳变”现象.据此总结了利用声波资料评价蒸汽波及范围与蒸汽前缘的解释方法，并进行了多井评价实验, 取得了满意结果.同时，也为利用孔隙介质弹性波动理论评价地下蒸汽分布范围的适用性提供了新的现场实际例证.

| Abstract: | According to the theory of poroelasticity and the results of associated laboratory works,this paper analyzes the cause of abnormal acoustic data in the steam thermal recovery heavy oil field.It is found that the injected steam causes the abnormal low velocity and very high attenuation of compressional wave.The evaluation method to identify the steam zone and the steam front as well as the behavior of the steam spreading in the oil reservoir has been developed.This method has been applied to the field data and found to work very well.This work may provide a new method to the monitoring and evaluation of heavy oil production.It is a good field example for evaluation of the steam zone with acoustic logs. |
