海洋三维地震勘探,是近几年才开展起来的一项新的工作,它在解决复杂地质构造问题、提高勘探精度等方面都具有很多独到之处。为使大家对海洋三维地震勘探野外工作方法有一个概略的了解,本文用不长的篇幅对这方面的情况作了一个简略的介绍,并用对比的方法说明了三维地震勘探与二维地震勘探在野外工作方法上的不同。 Marine 3D seismic exploration is a new work that has been carried out in recent years. It has many unique features in solving complicated geological structure problems and improving exploration accuracy. In order to make everyone have a general understanding of the working methods of 3D seismic exploration in the oceans, this paper gives a brief introduction of the situation in this area with a short space of history, and illustrates the comparison between 3D seismic exploration and 2D seismic exploration Different ways of working in the field.
