摘要
目前,由于滩海油田采油平台的可操作面积小,加之在平台上储存天然气的危险性极高,故油田伴生气经气液分离后多采用排火烧掉或放空的处理方式。从提高滩海油田经济效益、减少环境污染的角度出发,滩海油田伴生气的回收十分重要。现阶段国内外伴生气的回收方法主要有管道输送和把天然气加工成液化天然气、压缩天然气、吸附天然气和天然气水合物等进行输送的方法,也有一些油田利用伴生气发电。我国伴生气的回收刚刚处于起步阶段,为了高效的回收滩海油田伴生气,需要参照油田环境,设计一套技术性、经济性合理的回收方案。
At present, due to small operation area of offshore oilfield production platform and the high risk of natural gas storage on the production platform, the associated gas after gas-liquid separation is often burned or evacuated. In the view of enhancing the economic efficiency of the offshore oilfield and reducing pollution of the environment, the recovery of offshore oilfield associated gas is very important. Now the methods of associated gas recovery contain the pipeline transportation, processing gas into liquefied natural gas, compressing natural gas, adsorbing natural gas and natural gas hydrate;some oilfields use the associated gas for generation. The comprehensive utilization of associated gas in China is just in the initial stage. In order to efficiently recover the associated gas, an economic and reasonable recycling program should be designed based on the oilfield environment.
