油气勘探中的地震波速度
|
摘要
地震波在地层中的传播速度是油气勘探过程中一个很重要的参数,它贯彻在油气勘探的各个方面。严格来说,在同一岩层中的各个不同部分或沿不同方向,地震波的传播速度是不同的。但在现实中不可能达到这种精度,只能对极其复杂的实际情况作简化,建立各种简化介质模型,并使用不同概念的速度。本文对地震波速度的影响因素、获取方法、速度场的建立等作了简要的介绍,并且简单的列举了地震波速度在岩性解释中的应用过程。
Seismic velocity is a very important parameter.It can penetrate though every area in the oil and gas exploration.In strictly,seismic velocity can be different in the diverse parts of the same formation or from the different angle of incidence to the same formation.But it's impossible to reach such a precision,only to simplify the complicated situation,to establish simplified models,and use the different concept of velocity.In this paper,the impact factors of seismic velocity,access methods and the establishment of velocity field are briefly introduced,and also simply showed application processes of how.
