重力与地震联合解释在石油勘探中的应用

APPROACH OF GRAVITATIONAL AND SEISMIC INTEGRATED INTERPRETATION IN OIL EXPLORATION

重力与地震联合解释在国外已有不少人用于地热勘探与石油勘探。但在国内却没有得到应有的重视。原因之一在于,对已经有了地震资料之后,再去与重力资料进行联合解释能够获得更多资料这一点还认识不足。利用地震与重力资料进行联合解释的方法有很多种。本文介绍的一种方法是:利用地震构造图和层速度资料构成重力模型,计算其重力效应并与实测重力值对比,再进行联合解释。

In oil exploration,the gravitational and seismic integrated interpretation has been employed in other countries for some time, but it is not the case in our country.This is mainly because that there are some misunderstanding about this integrated interpretation and the significance of it is not fully aware of. What is really important is that after having the seismic data,such an integrated interpretation could still provide with some more useful information.The ways of integrated interpretations are various in kind. What is introduced here is to form a gravitational model by seismic structural map and interval velocities then, to estimate its effects in gravity and compare it with the measured values and then, make the final interpretation.
