Abstract
The present invention discloses a kind of special defoamer in oil field, by weight percentage, including：Polysiloxanes 20 50%；Nonionic surfactant 4 6%；Polyoxyethylene polyoxypropylene polymeric acid 40 60%；Mutual solvent 3 8%；Catalyst 0.1 0.2%；Dispersant 0.6 0.8%.30 60 minutes prepared special defoamers in oil field are stirred after above-mentioned substance is added.Wherein polysiloxane molecule amount is 1,000 5000, and nonionic surfactant is nitrogenous class, and mutual solvent is diethylene glycol butyric acid.Described nonionic surfactant is cetyl trimethylammonium bromide.Present invention specifically addresses froth breaking problem in oil exploitation or processing.The present invention is made up of nonionic surfactant with hydroxy compounds, and with outstanding dispersiveness and the suds that disappear, froth breaking is fast, suds are long.There is good suds effect for various mink cell focuses, light oil.Good stability of the present invention, and the compatibility of solvent is good.
Description
Technical field
The present invention relates to defoamer field, more particularly to a kind of special defoamer in oil field.
Background technology
In crude oil stabilization technology, gas mixture enters separator, and some stabilizations will be formed on the interface of oil and gas
Foam, when Oil-gas Separation, bubble burst has the loss of some liquid crude oils in the gas flow, in order to overcome these problems, it is necessary to
Defoamer is added in crude oil, and general defoamer is all pure silicon oil type defoamer, viscosity is big, is difficult to disperse in crude oil,
And dosage is big, defoaming effect is also not ideal enough.It is an object of the invention to provide a kind of improved crude oil antigassing additive, to solve
The foam that certainly crude oil is produced in Oil-gas Separation or crude oil stabilization process.Less developer low cost is reached, defoaming effect is preferable
Purpose.So as to improve the efficiency of oil gas separation equipment, oil and gas loss is reduced, improve yield；
Therefore, prior art has yet to be improved and developed.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of special defoamer in oil field, it is intended to solve
Certainly when oil gas product is processed, the defoaming effect that exists is undesirable, it is low to there is oil and gas loss, efficiency for the defoamer of prior art
Problem.
A kind of special defoamer in oil field, wherein：By weight percentage, including：
Polysiloxanes 20-50%；
Nonionic surfactant 4-6%；
Polyoxyethylene polyoxypropylene polymeric acid 40-60%；
Mutual solvent 3-8%；
Catalyst 0.1-0.2%；
Dispersant 0.6-0.8%.
The polysiloxane molecule amount is 1000-5000, and nonionic surfactant is nitrogenous class non-ionic surface active
Agent, mutual solvent is diethylene glycol butyric acid.
Described nonionic surfactant is cetyl trimethylammonium bromide.
Present invention specifically addresses froth breaking problem in oil exploitation or processing.The present invention matches somebody with somebody hydroxyl by nonionic surfactant
Compound group is into outstanding dispersiveness and the suds that disappear, froth breaking is fast, suds are long.Have very for various mink cell focuses, light oil
Good suds effect.Good stability of the present invention, and the compatibility of solvent is good.It is a kind of heavy duty detergent defoamer.

Embodiment 2：
A kind of special defoamer in oil field, wherein：By weight percentage, including：
Polysiloxanes 35%；
Nonionic surfactant 4.5%；
Polyoxyethylene polyoxypropylene polymeric acid 55%；
Mutual solvent 4.6%；
Catalyst 0.1%；
Dispersant 0.8%.
After above-mentioned each raw material is added into container, 40 minutes prepared special defoamers in oil field are stirred.
Wherein polysiloxane molecule amount is 2500, and nonionic surfactant is nitrogenous class, and mutual solvent is diethylene glycol fourth
Acid；Nonionic surfactant is cetyl trimethylammonium bromide.
Present invention specifically addresses froth breaking problem in oil exploitation or processing.The present invention matches somebody with somebody hydroxyl by nonionic surfactant
Compound group is into outstanding dispersiveness and the suds that disappear, froth breaking is fast, suds are long.Have very for various mink cell focuses, light oil
Good suds effect.Good stability of the present invention, and the compatibility of solvent is good.It is a kind of heavy duty detergent defoamer.
It should be appreciated that application of the invention is not limited to above-mentioned citing, and for those of ordinary skills, can
To be improved according to the above description or converted, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Shield scope.
