海洋地震调查固体拖缆应用技术概述

The solid streamer overview in marine seismic survey

固体拖缆是近年来推出的海洋地震调查新型水听器组阵列电缆,在充油拖缆的基础上,固体拖缆在结构设计、充填材料、水听器特性方面均有了改进,可以更有效地压制低频噪音,提高勘探作业效率,提高采集资料质量,并与充油拖缆有很好的兼容性。本文简要介绍了固体拖缆的结构及噪音压制方式,通过试验对比,指出固体拖缆在实际应用中的优势。

The Solid streamer is a new marine seismic survey hydrophones array cable launched in recent years. Based on the oil-filled streamer, the solid streamer has been improved in the structural design, filling materials and hydrophone characteristic, It can suppress lowfrequency noise more effectively, improve the efficiency of exploration operations, improve the quality of the acquisition data, and has good compatibility with the oil-filled streamer. This paper describes the structure of solid streamers and noise suppression way briefly, through sea-trial and comparision, we point out the solid streamer advantages in practical application.
