用地震法监测热采油过程

Manitoring the thermil recovery with the use of seismic method,

在稠油田的开发中,热采油方法(注蒸汽、火烧油层、注热水)已被广泛采用。但这些方法所面临的一个重要问题就是如何确定油层中的高温区及其前缘区位置和运动状态。本文结合了实验室结果和几个野外实例来说明地震法可以被用来圈划油层中的高温区,跟踪高温前锋以及测量高温区的体积等。采用高频,高分辨率地震勘测方法来进行细致的油藏描述及监测油田开发的全过程是可行的。

Thermal recovery (steam flooding, fire flooding or hot-water flooding) has been widely used in the development of thick-oil field. The common important problem the thermal recovery methods face is how to determine the high temperature extent in reservoir and the moving state of the high tempeiature front. Laboratorial result and some field examples are taken to show that we can use seismic method to map the high-temperature extent in reservoir, to track the high-temperature front, to measure the volume of the high temperature extent and so forth. It is feasible for us to apply high-frequency and high-resolution seismic methods to both the detailed description of reservoir and the monitoring of oil field development.
