海上三维地震勘探野外工作方法简介

A BRIEF ACCOUNT OF THE FIELD SERVICE ON 3-D MARINE SEISMIC SURVEY

南海石油勘探指挥部海洋物探大队

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。

3-D marine seismic survey is a new approach universally acknowledged and has been employed just recent few years. But it displays much originality in solving the problem of complex geological situation and ensuring favourably acceptable data resulted from actual survey, etc. In order to make the way of field service of 3-D marine seismic survey known to all in broad line, a brief introduction in this respect is concisely made here in this paper.Moreover, the difference of field layouts using 3-D and 2-D seismic survey is, by comparison, illustrated.
