Description
Technical field
The present invention relates to a kind of oil production auxiliary agent, particularly relate to a kind of novel emulsion viscosity-depression agent.
Background technology
Viscous crude occupies certain ratio on part oilfield reserve, the output structure at home and abroad.Find that in viscous oil recovery in recent years the crude oil liquid of most of viscous crude output is water-in-oil (being the O/W type) type emulsion liquid, the viscosity of this quasi-oil is big, mobile poor, brings many difficulties to exploitation.As, cause sucker rod load to increase, this not only consumes a large amount of electric energy, and resembles the also increase thereupon of mechanical accidents such as rod broken, poliched rod eye fracture, causes operation frequent; Viscosity of crude greatly also can make the surface pipeline back pressure raise, and has increased the difficulty of crude oil exporting, is difficult to improve manufacturing parameter, has a strong impact on crude production rate.
The reducing viscosity by emulsifying method is a present heavy crude producing method commonly used; Through the absorption of emulsifying pour depressor at water-oil interface, reduce oil water interfacial tension, make viscous crude change oil-in-water-type (W/O) milk sap into from the emulsified state of water-in-oil-type (being the O/W type); Can reduce viscosity significantly, be convenient to normal exploitation.
Yet in the emulsifying pour depressor that the oil field is used always, more emulsifying agent is a nonionogenic tenside, and the production cost of non-ionics is higher, and the ability of anti-rock salt is little.Also there is part petroleum assistant enterprise to develop the viscosity-depression agent of other type, reported with the composite method of sulfonated petro-leum, polyoxyethylene nonylphenol and the alkali of not condensation that like US4016932 can be used for total ion concentration is 125000mg/L (Ca as oil-displacing agent
2+, Mg
3+Be 5800mg/L) local water, but be not suitable for heavy crude producing and ultra viscous crude.
Summary of the invention
Problem to be solved by this invention is; To the deficiency of prior art and a kind of technical scheme of novel emulsion viscosity-depression agent is provided; This technical scheme can change viscous crude into oil-in-water-type (W/O) milk sap from water-in-oil-type (being the O/W type); Reduce the viscosity of viscous crude significantly, and the ability of anti-rock salt is strong, low cost of manufacture.
The present invention realizes like this; A kind of novel emulsion viscosity-depression agent; It is characterized in that it is mixed by the following weight proportion raw material: 63～65 parts of sulfonated petro-leums, 9～15 parts of ASs; 20～30 parts of pH value regulators, said pH value regulator are caustic soda with water is that 50:50 mixes and processes according to the weight part proportioning.
Said sulfonated petro-leum is a sodium laurylsulfonate; Said AS is that the following weight proportion raw material mixes: 35～45 parts of sulfonate type ASs; 20～25 parts of sulfonated alkylbenzene type ASs, 30～35 parts of carboxylic acid type ASs.
Said AS is mixed by the following weight proportion raw material: 40 parts of sulfonate type ASs, 25 parts of sulfonated alkylbenzene type ASs, 30 parts of carboxylic acid type ASs.
The pH value regulator just is meant acidity-basicity regulator.
The invention has the beneficial effects as follows, a kind of novel emulsion viscosity-depression agent that the present technique scheme provides, it is big to be suitable for the viscous crude scope; Both be applicable to that viscosity was lower than the viscous crude of 2400mPa.s; Be applicable to that also viscosity is higher than the viscous crude of 2400mPa.s, and it is strong to have anti-rock salt ability, can makes viscous crude change O/w emulsion into from water in oil emulsified state; Advantages such as the viscosity of thickened oil after the emulsification is low, and the emulsification cost is low.
