摘要

利用声波(或地震波)进行地下蒸汽和含气识别是孔隙弹性波动理论研究的应用方向之一。根据双相多孔介质声波传播理论与相关实验以及对于大量现场资料的统计分析结果,概括了蒸汽波及范围内声波测井响应在声学方面的2个特征,即声波速度的低异常和幅度的强衰减。据此总结了利用声波资料评价蒸汽波及范围的实用方法,并对实际资料进行了解释和分析,肯定了利用声波资料评价蒸汽波及范围的有效性和实用性,进一步考察了蒸汽波及范围对稠油生产的影响,为稠油剩余油描述及相关工作提供了新的信息和思路;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。
Steam zone or gas zone identification with elastic waves is the interest of the poroelasticity application.According to the theory of poroelasticity and results of associated laboratory works,analyzed is the cause of "abnormal acoustic data" in the steam thermal recovery of heavy oilfield.It is found that the injected steam causes the abnormal low acoustic velocity and very high acoustic attenuation.The evaluation method to identify steam front and steam zone as well as behavior of the steam spreading in the oil zones has been developed.This method has been applied to the field log data and works very well.This method may provide a new means for the monitoring and evaluation of heavy oil production.It is a good field example for evaluation of the steam zone with acoustic logs.
