随着东海海域油气勘探开发开采工作的不断进行,我单位先后承担了礁一井、富阳一井、春晓一井、春晓二井、春晓三井、春晓四井、春晓五井、天外天二井、天外天三井、残雪二井等众多井场勘探钻井平台的拖航定井位工作。通过这些项目的实施,逐步形成了一套比较成熟的作业方法,积累了丰富的施工经验。文章对GPS技术作简要的介绍之后,详细阐述了GPS定位仪在半潜式勘探钻井平台拖航定井位的应用全过程,并试图对平台拖航定井位这一过程提出探讨性的建议,以供参考。

Along with the offshore oil and gas exploration and mining in the East China Sea,our company has successfully undertook the following well yard exploration projects and drilling platform towing projects,such as Jiao-1,FuYang-1,ChunXiao-1,ChunXiao-2,ChunXiao-3,ChunXiao-4,ChunXiao-5,TianWaiTian-2,TianWaiTian-3,CanXue-2 and etc. Through implementations of these projects,we have formed a set of quite successful operating procedures,and accumulated rich experiences in such projects. In this article,we briefly introduced the GPS technology. Then we elaborated the application of the positioning instrument of GPS in the entire process of the tow positioning well for the Semi-submersible platform. And we also gave some suggestions about such a process as a reference to people concerned.
