Abstract
The present invention relates to an emulsifying and viscosity reducing agent which is used for hot injection of oil fields, and emulsification combustion of super thick oil of heating boilers. The emulsifying and viscosity reducing agent is prepared by that three or more than three surface active agents, catalytic combustion supporting agents, stabilizing agents and solvent are uniformly stirred and mixed according to a certain proportion, and then, water is added for dilution. The emulsifying and viscosity reducing agent has favorable emulsifying and viscosity reducing properties and has the advantages of low price and wide source of raw materials, favorable compatibility and convenient preparation and production. The present invention can be utilized to greatly improve the fluidity and the combusting effect of super thick oil and make coning oil resources fully utilized.
Description
The present invention relates to a kind of emulsifying pour depressor that oil field heat is annotated, the super emulsified viscous oil of heating boiler is burnt that is used for.
Super viscous crude occupies certain ratio on part oilfield reserve, the output structure at home and abroad.Yet, because this kind crude oil with poor quality oil property extreme difference makes its utilization be subjected to limiting greatly, even also have certain difficulty when utilizing it as boiler oil.At present, demand urgently seeking, develop some and can reduce super viscosity of thickened oil significantly, improves super viscous crude combustion efficiency, enable to obtain the more chemical agent of good utilisation, to solve super viscous crude production, to utilize the institute of technology scarce.
The object of the present invention is to provide a kind of super emulsified viscous oil burning emulsifying pour depressor that can improve super viscous crude flowability and combustion efficiency.
The present invention realizes like this.Emulsifying pour depressor provided by the present invention adopts following prescription:
| Component | Percentage by weight (%) |
| Surfactant catalysis burning-rate accelerator stabilizing agent solvent | 50--80 0--10 20--50 0--10 |
Wherein: it is that among NP-20, NP-25, NP-30, NP-40, the NP-50 one to two kind, polyoxyethylene sorbitol acid anhydride trioleate are a kind of in a kind of, the dodecyl sodium sulfate, neopelex, lauryl sodium sulfate Sodium stearate, enuatrol, polyoxyethylene groups polyoxypropylene base ether, dodecyl alcohol polyoxyethylene base ether in Tween-20, the Tween-40 that surfactant can adopt alkyl phenol polyoxyethylene base ether; Catalysis burning-rate accelerator can adopt a kind of in nitric acid octyl group ester, the own ester of nitric acid; Stabilizing agent can adopt a kind of in polyethylene glycol, ammonia, alkylamine, potassium hydroxide, NaOH, the sodium carbonate; Solvent can adopt a kind of in water, methyl alcohol, ethanol, the propyl alcohol.
During preparation, add various components according to above-mentioned formula rate, thin up is the emulsifying pour depressor aqueous solution of concentration 10--20% behind the stirring and evenly mixing, uses for the super thick oil and emulsified oil of preparation.When the preparation oil emulsion, the dose that adds of this kind emulsifying pour depressor is 1--3 ‰, and the water mixing rate is 15--30%, and the viscosity break ratio of oil emulsion is more than 90% under 80 ℃ of temperature, and its heat endurance can keep more than 30 days.
Super emulsified viscous oil burning provided by the invention has good emulsifying, viscosity-reducing performance with emulsifying pour depressor, its cheap raw is wide, and compatibility is good, prepares convenient for production, utilize it can improve the flowability and the combustion efficiency of super viscous crude greatly, super viscous crude resource is fully used.
