胜利油田现有各类管道两万余条,总长约15000余km.由于进入特高含水生产期,油田地面生产系统的主要部分基本上已属于一个高含油污水系统.由于特殊修井措施及三次采油技术的应用,采出水总矿化度逐年升高,易腐蚀、结垢的离子增加,溶解氧、侵蚀性二氧化碳、硫化物等腐蚀性介质存在,以及SRB、TGB细菌的大量繁殖,致使高含水集油
Shengli Oilfield has more than 20,000 pipelines of various types with a total length of more than 15,000 km. As a result of entering the ultra-high water-cut production period, the major part of the oilfield ground production system basically belongs to a high-oily wastewater system. Due to special well-servicing measures and three The application of oil recovery technology, the total salinity of produced water increased year by year, the corrosion of ions, scaling ions, dissolved oxygen, aggressive carbon dioxide, sulfide and other corrosive media, and SRB, TGB bacteria multiply, resulting in high Water-based oil collection
