海底钻井平台将寻找石油的区域延伸到了海洋大陆架——大陆边缘那些平缓倾斜的海底区域。

Offshore drilling platforms extend the search for oil to the ocean's continental shelves—those gently sloping submarine regions at the edges of the continents.

而陆地钻井由于空间不成问题，管架一般具有较少的层数，并根据需要横向延伸去存储管柱。

The onshore pipe rack tends to have few stacked layers and instead extends laterally as needed to hold the tubular goods because space is not at a premium.
