Preparation and application method of surfactant

Abstract

The invention belongs to the field of treating heavy oil, and relates to a preparation and application method of a surfactant. The surfactant is characterized by comprising the following components: 10-20% of phosphatide, 5-20% of tween-80, 5-20% of diethanolamine, 5-20% of AES (acrylonitrile), and the balance of water. The preparation method comprises the following steps: pouring the water into a reaction kettle, adding the quantitative diethanolamine and phosphatide to the reaction kettle at the same time, raising the temperature to 80 DEG C, and stirring the mixture for 2 hours at a constant temperature until the diethanolamine and the phosphatide are fully dissolved; adding the quantitative AES, raising the temperature to the range of 75 DEG C to 85 DEG C, and stirring for an hour at the constant temperature; then adding the tween-80, stirring for an hour at the constant temperature of 80 DEG C, reducing the temperature to 40 DEG C, and loading finished products into packing buckets according to measurement so as to obtain the finished products of the surfactant. The surfactant can be used as a thick oil viscosity-reducing agent, an asphalt emulsifying agent or an oil mixing agent for use. The surfactant has good emulsifiability and is wide in application field, heavy oil can be easily emulsified into the water through the surfactant, the viscosity reducing rate is as high as 99.99%, and the oil-water interfacial tension can be greatly reduced.

Description

Technical field: [0001] The invention belongs to the field of heavy oil treatment and relates to a production and application method of a surfactant. technical background: [0002] At present, in the exploitation of heavy oil and the construction of roads and roads at home and abroad, most of them use the traditional thermal method to reduce the viscosity of heavy oil, consume a lot of fuel, produce a lot of pollution, and the cost is high and the output is very low, especially in the current "heavy oil". In the era of high-quality oil, the low production has become the bottleneck of heavy oil exploitation, which directly affects the energy supply and security of human beings; therefore, all countries in the world have been struggling to find a new viscosity-reducing technology for nearly a hundred years. Invention content: [0003] The object of the present invention is to solve the problems of high cost and low output of emulsified heavy oil, and provide a method for...
