摘　　要：深拖系统可有效缩短调查仪器与勘察目标之间的距离,是目前我国进行深水油气田井场调查中应用最广泛的技术之一。首先简要介绍深拖系统的组成以及开展深水井场调查的作业流程,然后以近年来在南海深水区开展的井场调查作业为例,对比利用深拖系统和常规调查技术获取的勘察资料在密度和分辨率等方面的差异,探究深拖系统的技术特点和应用优势。结果表明:相对于常规调查技术,深拖系统在提升深水井场勘察资料的准确性和可靠性方面具有明显优势。At present, the deep tow system which can shorten the distance between survey instruments and prospecting targets effectively, is one of the most widely used techniques in the investigation of deepwater oil or gas field in China. This paper will give a brief intro-duction for the composing of deep tow system and how deep tow system works for well site investigation in the deep water sea area. Taking well site investigation in the deep water ar-ea of South China Sea as an example, this paper compares differences in the density and res-olution ratio of survey data which gain from the deep tow system and the conventional sur- vey technique, to study the technical features and applied advantages of deep tow system. The results show that the deep tow system has the obvious advantages in improving the ac-curacy and reliability of acquiring data for well site investigation in the deep water sea area with the comparison of conventional survey methods,
