[0002] Old emulsified sludge in oil fields usually refers to a complex mixture of crude oil, water, solid particles (such as sand, rock fragments), chemical additives and microbial metabolites produced during the development of oil fields. During long-term production operations, due to physical and chemical effects, these mixtures will form a stable emulsified state, namely, water-in-oil (W / O) or oil-in-water (O / W) emulsions, which are difficult to separate simply by gravity.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: there are many ways to treat old emulsified sludge. Due to its high emulsification and high viscosity, solidification treatment technology is one of the best methods, which is to mix the sludge with a curing agent to transform it into a stable, non-penetrable solid material. During the sludge solidification process, the curing agent is generally added to the mixing box at one time to mix with the sludge. The one-time addition of the curing agent is prone to uneven mixing with the sludge, affecting the treatment effect of the sludge; therefore, in view of the above problems, a treatment device for old emulsified sludge in oil fields is proposed.
