Technical field
The present invention relates to be used for the emulsifying pour depressor and the using method thereof of Oil extraction and conveying.
Technical background
The gas-free oil that 50 ℃ of following viscosity surpasses 100mPa.s is called viscous crude.Owing to contain a large amount of colloids and bituminous matter in the viscous crude, thermal recovery technology exploitations such as steam stimulation commonly used and steam flood.But too high or oil reservoir is crossed when dark when viscosity of thickened oil, needs to adopt the reducing viscosity by emulsifying method to improve the oil displacement efficiency of steam flood and steam stimulation.Promptly, promptly add viscosity-depression agent, make crude oil form low viscous oil-in-water emulsion, be convenient to normal exploitation by emulsification dispersing method viscosity reduction.In addition, this viscosity-depression agent can also be added in the viscous crude of extraction, realizes the low viscosity conveying.
Along with the increase of the viscous oil recovery degree of depth, geologic condition is complicated day by day.The result of use of emulsifying pour depressor can be subjected to the influence of stratum water quality salinity usually; especially in the water during calcium ions and magnesium ions excessive concentration; be easy to react with the anionic emulsifying pour depressor; form precipitation, the increase of electrolyte concentration even can make water external emulsion be full-bodied water-in-oil emulsion transition.At present, commercially available emulsifying pour depressor when running into calcium ions and magnesium ions concentration and be higher than the 7000mg/L local water, mostly loses the viscosity reduction effect.And calcium ions and magnesium ions concentration has not yet to see the reducing viscosity by emulsifying technology at this class oilfield application example up to 2000mg/L-30000mg/L in the local water in oil fields such as domestic Xinjiang, Central Plains.
The application example of emulsifying and viscosity-reducing agent for condensed oil is more both at home and abroad, for example:
US 4333488 has reported the method with ethylene oxide-propylene oxide copolymer emulsification viscous crude, is 80% for the viscosity break ratio of 21 ℃ of viscosity Loco viscous crude that is 340cp, and the mineralized water that is suitable for is total ion concentration 12000mg/L (wherein calcium magnesium is 730mg/L).
US 4355651 has reported the method with phosphoric acid ester multipolymer emulsification viscous crude, at calcium magnesium plasma concentration is in the mineralized water of 500-2000mg/L, and adding dosage is 2500ppm, but emulsification Goodwin lease viscous crude after the stirring, viscosity of thickened oil can be reduced to 400cp from 3060cp at 27 ℃
US 5934303 has reported a kind of method of using sodium salt, magnesium salts or the ammonium salt emulsification viscous crude of naphthalene sulfonic acidformaldehyde condensation product, at total ion concentration is to be suitable in the local water of 38000mg/L (calcium magnesium is 6200mg/L), but in emulsion process, need be undertaken by the stirring of 10000rpm, adding dosage is 0.42% o'clock, 25 ℃ of viscosity can be reduced to 688mPa.s greater than the OG3 viscosity of thickened oil of 40000mPa.s.
In addition, CN 88105018A has reported that also CN1064498A has reported emulsifying pour depressors such as polyoxyethylene polyoxypropylene alkylbenzene phenolic ether with the method for polyxyethylated alkylphenol emulsification viscous crude.
The production cost of above-mentioned all surface promoting agent is higher, and the ability of anti-rock salt is generally less than 7000mg/L, and when the calcium ions and magnesium ions concentration of local water was higher, above-mentioned emulsifying pour depressor all can not use.
Summary of the invention
The object of the present invention is to provide a kind of anti-rock salt emulsifying and viscosity-reducing agent for condensed oil.
Another object of the present invention is to provide the using method of above-mentioned emulsifying and viscosity-reducing agent for condensed oil.
