Abstract
The present invention relates to technical field of surfactant, especially a kind of stable emulsion visbreaking agent, it is made of the raw material of following parts by weight: 0.3 ~ 0.6 part of nonylphenol polyoxyethylene ether, 0.6 ~ 1.2 part of P-hydroxybenzoic acid, 0.3 ~ 0.8 part of sulfuric acid, 5 ~ 10 parts of water, 1 ~ 1.5 part of formaldehyde, 6 ~ 9 parts of sodium hydroxide, wherein, 0.5 part of nonylphenol polyoxyethylene ether, 0.8 part of P-hydroxybenzoic acid, 0.5 part of sulfuric acid, 5 parts of water, 1.2 parts of formaldehyde, 8 parts of sodium hydroxide, the activity of visbreaking agent made from the proportion is strong, surface tension is low, to paraffin, colloid and pitch have preferable washing, the glutinous effect of drop, can reach reduces oil reservoir viscosity, improve the purpose of the recovery ratio of oil reservoir.
Description
Technical field
The present invention relates to technical field of surfactant, especially a kind of stable emulsion visbreaking agent.
Background technique
Emulsifier is can to improve the various surface tension constituted between phase in emulsion, is allowed to form uniform and stable point
The substance of granular media system or emulsion, emulsifier are surface reactive materials, have hydrophilic group and lipophilic group simultaneously in molecule, it assembles
On oil/water interface, interfacial tension can be reduced and reduction forms energy required for emulsion, to improve the energy of emulsion
Amount.
It is currently used for the visbreaking agent poor activity of oil well emulsification, thinning effect is poor, can not meet growing use demand.
Summary of the invention
Existing above-mentioned in order to overcome the shortcomings of, the present invention provides a kind of stable emulsion visbreaking agents.
The technical solution adopted by the present invention to solve the technical problems is: a kind of stable emulsion visbreaking agent, by following weight
The raw material composition of part: 0.3 ~ 0.6 part of nonylphenol polyoxyethylene ether, 0.6 ~ 1.2 part of P-hydroxybenzoic acid, 0.3 ~ 0.8 part of sulfuric acid, water
5 ~ 10 parts, 1 ~ 1.5 part of formaldehyde, 6 ~ 9 parts of sodium hydroxide.
Further, including 0.5 part of nonylphenol polyoxyethylene ether, 0.8 part of P-hydroxybenzoic acid, 0.5 part of sulfuric acid, 5 parts of water,
1.2 parts of formaldehyde, 8 parts of sodium hydroxide.
The invention has the advantages that the activity of visbreaking agent made from the proportion is strong, surface tension is low, to paraffin, colloid and
Pitch has the glutinous effect of preferable washing, drop, can reach the purpose for reducing oil reservoir viscosity, the recovery ratio for improving oil reservoir.
Specific embodiment
A kind of stable emulsion visbreaking agent, is made of the raw material of following parts by weight: 0.3 ~ 0.6 part of nonylphenol polyoxyethylene ether,
0.6 ~ 1.2 part of P-hydroxybenzoic acid, 0.3 ~ 0.8 part of sulfuric acid, 5 ~ 10 parts of water, 1 ~ 1.5 part of formaldehyde, 6 ~ 9 parts of sodium hydroxide, wherein
0.5 part of nonylphenol polyoxyethylene ether, 0.8 part of P-hydroxybenzoic acid, 0.5 part of sulfuric acid, 5 parts of water, 1.2 parts of formaldehyde, sodium hydroxide 8
Part.
The activity of visbreaking agent made from the proportion is strong, and surface tension is low, has preferable washing, drop to paraffin, colloid and pitch
Glutinous effect, can reach the purpose for reducing oil reservoir viscosity, the recovery ratio for improving oil reservoir.
Described above to be merely exemplary for the purpose of the present invention, and not restrictive, those of ordinary skill in the art understand,
In the case where not departing from spirit and scope as defined in the appended claims, many modifications, variation or equivalent can be made, but all
It will fall within the scope of protection of the present invention.
