海上油田伴生气利用问题探讨

Approaching the Utilization of Associated Gas of Offshore Oil Field

近年来,在我国海上发现的一些油田中,在生产原油的同时,还产出大量的伴生气。有的油田产出的伴生气量高达几十万m^3/d。这些伴生气除一小部分用于油田生产外,大部分都放空烧掉了。因此,如何利用这部分伴生气是人们十分关心的问题。但是,由于海上油田远离岸边,处于较深水域,再加上生产上的特点,要利用好这部分伴生气还存在不少技术与经济上的问题。本文对上述问题做了初步探讨,可供制订利用方案时参考。

A great amount of associated gas has been produced in some of China 'i present offshore oil fields in recent yean togcther with the crude oil production. The amount of the associated gas in some oil fields is highly up to several hundred thousands of cubic meters a day. Most part of the associated gas is flaring except a small put of it for use offshore. Therefore it becomes a much concerned question of how to utilize the associated gas. Quite a few technical and economic problems still remain in the better utilization of the associated gas because the offshore oil fields arc located far from shore and in comparatively deep waters and because it has a unique production characteristics. A preliminary approaching of the abovesaid problem has been made, and it can be referred for the utilization programme making.
