立式除油罐是油田含油污水处理站的主要除油构筑物,但至今尚无一套完整的水力计算方法,在生产中常出现冒顶和不易收油等现象。本文总结了大庆油田50余座立式除油罐的设计、运行经验,并根据水力学基本原理,对三种结构形式的除油罐的集水、出水、溢流和保护高度等进行了水力计算,还附有例题,可供设计人员参考。 Vertical oil removal tank is the main degreasing structure of oily wastewater treatment station in oilfield. However, there is no complete set of hydraulic calculation methods so far. It often appears the phenomenon of falling out of roof and not receiving oil easily in production. This paper summarizes the design and operation experience of more than 50 vertical oil removal tanks in Daqing Oilfield. Based on the basic principles of hydraulics, the hydraulic, hydraulic and hydraulic characteristics of three types of oil removal tanks, such as water collection, Calculation, but also with examples, for designers reference.
