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。 Joint explanation of gravity and earthquake in many foreign countries have been used for geothermal exploration and oil exploration. However, it has not gained the due attention domestically. One of the reasons is that there is not enough understanding of how more information can be obtained after the seismic data have been available and then the joint interpretation with the gravity data. There are many ways to use joint interpretation of seismic and gravity data. One of the methods introduced in this paper is to use the seismic tectonics and velocity data to compose the gravity model, calculate the gravity effect and compare with the measured gravity value, then make a joint interpretation.
