Abstract
The present invention relates to an emulsifying viscosity-reducing agent for emulsifying combustion of ultraheavy crude for oil-field hot injection and heating boiler. Said emulsifying viscosity-reducing agent is made up by using three kinds or more than three kinds of surfactants and catalytic combustion adjuvant, stabilizing agent and solvent through such steps as proportioning, stirring, uniformly mixing and dilution by adding water. Said invented product has good emulsifying and viscosity-reducing properties, can greatly improve fluidity of ultraheavy crude and its combustion effect, and its raw material source is extensive and cost is low.
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--90 ??????0--10 ??????15--50 ??????0--20 |
Wherein: surfactant can adopt sodium alkyl sulfonate, sodium alkyl benzene sulfonate, alkylsurfuric acid ester sodium salt, alkylol polyoxyethylene groups ether, alkyl phenol polyoxyethylene base ether (NP15--100), fatty acid polyglycol chlorovinyl ether, tween--and N (N=20--85), sodium soap, polyoxyethylene groups polyoxypropylene base ether, each preparation are to select wherein that surfactant is used more than 3 kinds or 3 kinds for use; Catalysis burning-rate accelerator adopts alkyl nitrate; Stabilizing agent can adopt alkaline matters such as polyethylene glycol and ammonia, alkylamine, potassium hydroxide, NaOH, sodium carbonate; Solvent can adopt water or methyl alcohol, ethanol, propyl alcohol, butanols etc.
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.
Embodiment 1: get 25kgNP--50,20kg tween--20 and 25kg polyoxyethylene groups polyoxypropylene base ether make surfactant, the just own ester of 10kg nitric acid is made catalysis burning-rate accelerator, 20kg polyethylene glycol used as stabilizers behind the stirring and evenly mixing, can obtain super emulsifying and viscosity-reducing agent for condensed oil 100kg.After should super emulsifying and viscosity-reducing agent for condensed oil adding the aqueous solution that water is made into concentration 10--20%, add dose by 2.5 ‰ and prepare oil emulsion and can make fuel usefulness by boiler of feeding.
