东营凹陷三维地震采集评述

近30年,来东营凹陷共采集67块三维地震资料,基本覆盖了整个凹陷。本文简要介绍了该凹陷三维地震勘探的历程,对其三维地震采集技术进行了后评估;根据凹陷内2块二次采集的三维地震资料结果,对即将到来的大规模第二次高精度三维地震采集提出几点建议。

3D seismic acquisition review of Dongying Sag

Sixty seven blocks of 3D seismic data have been acquired in Dongying sag in the last 30 years and the entire sagwere almost covered. This paper generally introduced the course of 3D seismic exploration of this sag, and conductedpost evolution on 3D seismic acquisition technique; Some ideas were suggested to the up-coming second large-scalehigh precision 3D seismic acquisition based on the results of re-acquired 2 blocks of 3D seismic data in the sag.
