一、概况海上油田勘探同陆上油田勘探一样,都需要经过对含油气盆地(地区)进行石油地质区域勘探、地球物理勘探、钻预探井、资源评价等一系列勘探来实现。只是海上油田勘探要受环境条件制约,因此具有很多特色。地球表面由三分陆地,七分海洋组成。在海洋的大陆架(陆棚)区,石油资源非常丰富,约占世界石油总储量的三分之一以上。1977年,海上石油的产量已经上升到世界石油总产量的20%。 I. Overview Offshore Oilfield Exploration Like onshore oilfield exploration, oil exploration needs to be accomplished through a series of exploration of oil-gas basins (regions) for petroleum geology, geophysical prospecting, drilling pre-exploration wells and resource assessment. Only offshore oil exploration to be subject to environmental conditions, so has many features. The surface of the earth consists of three terrestrial and seven oceans. In the continental shelf (shelf) area of ​​the ocean, oil resources are abundant, accounting for more than one third of the world’s total oil reserves. In 1977, the production of offshore oil has risen to 20% of the world’s oil production.
