Problems solved by technology

The disadvantage of ordinary non-ionic surfactants is that the cloud point is low, not only cannot be used in formations where the temperature exceeds the cloud point, but also the cloud point decreases with the increase of the salt content in the water

Abstract

The invention relates to a polyoxyethylene sulfonate and a synthesis method thereof. The polyoxyethylene sulfonate is prepared through a sulfonation reaction of an allyl derivative and sulfite sulfite according to a content ratio of 1:1.1, wherein the allyl derivative is prepared through reacting polyoxyethylene ether and oxypropyl hydrocarbon with NaOH according to a weight ratio of 1:1.2. The synthesis method comprises the following steps: dissolving NaOH, introducing N2, adding polyoxyethylene ether and oxypropyl hydrocarbon at 120-150DEG C, mixing and stirring for 1-2h, adding sulfite, and stirring for 4-6h. The polyoxyethylene sulfonate is an amber viscous liquid, the solid phase content is 50%, the pH value application range is wide, and the polyoxyethylene sulfonate has excellent foaming performance in a water phase medium and a non-aqueous phase medium. The above surfactant resists high temperatures, has obviously better rock salt resistance than petroleum sulfonate and other alkylaryl sulfonates, and is suitable for chemically assisted high temperature viscous oil viscosity reduction.

Description

technical field [0001] The invention relates to the technical field of surfactants in chemical auxiliary viscosity reducers for high-temperature recovery of heavy oil, and relates to a polyoxyethylene sulfonate and a synthesis method thereof. Background technique [0002] As the oil production formation gets deeper and deeper, the use temperature of the surfactant is higher and higher, and the salinity of the water quality is also higher and higher. The disadvantage of common non-ionic surfactants is that the cloud point is low, not only cannot be used in formations where the temperature exceeds the cloud point, but also the cloud point decreases with the increase of the salt content in the water. In order to overcome the weakness of the above-mentioned nonionic surfactants. Two kinds of hydrophilic groups (nonionic group and anionic group) with different properties are designed in the same surfactant molecule, which can have the advantages of both anionic and nonionic surf...
