Abstract
Description
technical field
[0001] The invention relates to the technical field of oil-water treatment on the surface of an oil field, in particular to an integrated treatment method for chemical flooding and production of emulsion. Background technique
[0002] As the oilfield enters the later stage of development, in order to stabilize crude oil production, the main oilfields in the east have promoted and applied tertiary oil recovery technology on a large scale. Here comes the difficulty. In the mine field, the viscosity of the produced fluid increases, and the oil-water separation of the produced crude oil emulsion becomes more difficult; the "intermediate layer" of crude oil appears in the settling tank of the oil station, the dehydration temperature increases, and the thermogravity settling time prolongs. The energy consumption of the oilfield ground gathering and transportation system is increased, the efficiency of thermal gravity sedimentation is reduced, the efficiency of the...
