油气勘探中大地坐标系的特点及其应用

Characteristics and application of geodetic coordinate system to petroleum exploration

概述大地坐标系的定义及国内外常用大地坐标系的特点,并讨论了它们之间的区别与联系,阐述了大地坐标系在海洋油气勘探领域中的应用。WGS84坐标与CGCS2000坐标之间误差极小,二者在油气勘探中可互用。在今后一段时期内,WGS84仍将是油气勘探中所使用的主要坐标系。

In this paper a brief introduction has been given to the definition and main features of the common geodetic coordinate system at home and abroad,the differences and similarities between them have been discussed,and application results of geodetic coordinate system in the field of offshore petroleum exploration are finally presented.There is minimal error between WGS84 coordinate and CGCS2000 coordinate,which can be used both in oil and gas exploration.WGS84 will still remain the main coordinate system used in petroleum exploration.
