Description
Technical field
The present invention relates to a kind of treatment process of three oil recovery mud.
Background technology
Along with the continuous exploitation in oil field, oil recovery technique constantly develops.Successively experienced once, secondary, TOR.Primary oil recovery is a power by natural energy; Secondary oil recovery keeps bottom pressure with the man-made injection mode; TOR is to improve tar productivity through changing the characteristic of injecting water, mainly carries out secondary, TOR at present.Be called " extraction liquid " from the wet oil of underground extraction, through electro-dewatering, the water of separating is called " oil field extracted water ", also claims " oilfield sewage ".In field produces, most of oil field extracted water is the re-injection bottom after treatment, has on a small quantity to efflux.The different in kind of the oil field extracted water of Different Strata, different oil production methods.At present, the processing for recovered water on the oil field mainly is to adopt the method for physics to remove the materials such as oils in the water, and deoiling method commonly used is treatment processs such as natural subsidence, inclined plate grease, air supporting, filtration.Important device air flotation cell as oil removing has all obtained application in many oil recovery factories, is generally the raising daf efficiency, all adds aluminium salt in the air supporting process or gathers aluminium etc. as flotation agent.
Along with continuing to increase of oilfield exploitation difficulty, tertiary oil recovery technology has obtained large-scale application, adopts tertiary oil recovery technology can effectively improve the RF in oil field, but has also brought the difficulty of wastewater treatment thus.Because the chemical agent that uses in the TOR is brought in the waste water, caused oleaginousness height in the waste water, the oily water separation difficulty.For effective oil removing; Need to add a large amount of flotation agent in the air supporting process; Flotation agent after these air supportings finish and the mud in the oil recovery process, oil and water have constituted three oil recovery mud (for example, contain the air supporting slag of flotation agent, the greasy filth etc. that lands all is called three oil recovery mud).
The processing for oily sludge focuses mostly on aspect the separation and oil recovery of oil, mud, for example in the document at present:
CN101037286A discloses a kind of oil-removing treatment process of oil-containing sludge; This technology comprises mixes with scavenging solution oily sludge in preheating conditioning jar; Heating; Remove fluid surface come-up sump oil, the mud after the preheating is carried out ultrasonic heat wash, and butyraceous mud is carried out air supporting to reclaim the sump oil in the mud.
CN1373096A discloses a kind of process for treating oily mud by phase transfer method, and this method utilization is caught finish the oil in the mud is reclaimed.
The volume of the three oil recovery mud that the method that adopts prior art three adopts air supporting slag that waste water carries out producing in the pneumatically supported process to containing, land greasy filth and oil and water etc. is big (solid content is bigger), water ratio height and costs and poor dehydration results, is difficult to handle with conventional method.In addition, the method for prior art can't reclaim the flotation agent in the three oil recovery mud.
Summary of the invention
The objective of the invention is to overcome that the method that adopts prior art three is adopted air supporting slag that waste water carries out producing in the pneumatically supported process to containing, the dehydrating effect of the three oil recovery mud of big (solid content is bigger) is relatively poor for the volume that lands greasy filth and oil and water etc.; And the defective that can't reclaim to the flotation agent in the three oil recovery mud; A kind of water ratio that can make effective reduction by three oil recovery mud is provided, and the treatment process of three oil recovery mud of the flotation agent in can efficient recovery three oil recovery mud.
Contriver of the present invention finds; Three oil recovery mud contain three to be adopted air supporting slag that waste water carries out producing in the pneumatically supported process, lands greasy filth and oil and water etc.; Wherein, The air supporting slag contains mud, oil and wrapping portion flotation agent, and the volume of this three oil recoveries mud is big, water ratio is higher, is difficult to handle with the method for prior art.Contriver of the present invention is surprised to find that; Mix with said three oil recovery mud with acidic aqueous solution earlier, can make most flotation agent soluble in water the flotation agent dissolving that wherein is wrapped; Then carry out three phase separation; Then, can realize removing minor amount of oil and the purpose of water of mud in mutually when mixing mutually with the mud that obtains after alkaline aqueous solution and the three phase separation more well, flotation agent remove the volume that can reduce solid matter in the greasy filth; Simultaneously also make mud dewater more easily, thereby realize effectively reducing the purpose of the volume of three oil recovery mud.In addition, through can be reused for after the pH value of regulating the isolated water that is dissolved with flotation agent three adopt waste water dissolved air flotation, realized the recovery of flotation agent, practiced thrift resource, and reduced cost.
The invention provides a kind of treatment process of three oil recovery mud, said three oil recovery mud contain water, oil and mud and inorganic flotation agent; Wherein, this method comprises the steps:
(1) three oil recovery mud is contacted with the acidic aqueous solution mixing; The mixture that mixes after contacting is carried out three phase separation, obtain first oil phase, first water and first mud mutually;
(2) first mud that step (1) is obtained contacts with the alkaline aqueous solution mixing; The mixture that mixes after contacting is carried out three phase separation, obtain second oil phase, second water and second mud mutually.
Compare with the method for prior art, the treatment process of three oil recovery mud provided by the invention has following significant advantage: first: method of the present invention has effectively reduced the volume of the solid matter in the three oil recovery mud, and mud is dewatered more easily; Reduced the water ratio of the mud that obtains; Thereby reduced the volume of greasy filth, and efficient recovery the sump oil in the greasy filth, protected environment; Can not bring secondary pollution, have tangible economic benefit, social benefit and environmental benefit; The second, the flotation agent of method of the present invention in can efficient recovery greasy filth has been saved the cost that flotation agent is handled again, and has been practiced thrift resource.
