深水油气田井场调查内容及方法技术研究

随着海洋油气资源开发的深入发展，我国的油气勘探开发已由浅海转向深水海域，深水井场调查是深水油气田勘探开发过程中的一个重要环节，但目前国内尚未开展此项工作，深水井场调查的内容和方法技术较浅水区相比有较大差异，难度较大。通过调研并结合以往浅水区井场调查经验，对深水井场工程地质及环境地质调查的内容和方法技术作了研究。针对深水海区地质环境条件和地质灾害因素复杂等特点，详细探讨了深水井场调查的技术难点和调查研究内容，重点介绍了深水井场调查的技术方法，特别是水下声学定位、深拖、水下机器人和深水地质取样等调查技术，以期为我国深水井场工程地质调查内容和技术方法的研究提供参考。

Study on well site investigation contents and techniques in deepwater oil and gas field

With the development of offshore oil and gas, the development and exploration have been expanded from shallow water to deep water in China. The deepwater site survey is an important part in the process of oil and gas exploration and development, but it has not been done in China yet. The investigation contents and technique for deepwater site are very different from the shallow water. Through summing up the experience of the shallow site survey, the investigation contents and techniques of deepwater site are studied in detail in this paper, such as underwater acoustic positioning, deep tow, ROV, AUV and geological ,sampling, etc. This article is designed to provide reference for the deepwater site survey.
