Abstract

The invention discloses an efficient demulsifier for petroleum and a preparation method thereof; the efficient demulsifier for petroleum comprises, by weight, 10-20 parts of water-soluble sodium sulfonate, 5-15 parts of mineral spirit, 10-20 parts of castor oil, 5-10 parts of pine oil, 8-18 parts of polypropylene glycol, 4-12 parts of sodium nitrite, 5-10 parts of polyether-modified trisiloxane, 3-8 parts of methanol, 4-10 parts of triethanolamine, 5-10 parts of nano titanium dioxide powder, and 3-9 parts of silica powder. The preparation method is simple and low in cost; the efficient demulsifier for petroleum prepared can provide increased deoiling rate, has good demulsifying performance for crude oil emulsion, and can save time, manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of demulsifier preparation, in particular to a high-efficiency demulsifier for petroleum and a preparation method thereof. Background technique [0002] With the development of the world's petroleum industry, the amount of oil production is increasing day by day, which makes the amount of crude oil emulsion increase day by day. Especially after water injection is used to enhance oil recovery, the water content of crude oil increases significantly, and most of the crude oil is extracted in the form of oil-water emulsion. . Crude oil production fluid contains a large amount of water and inorganic salts, which brings great difficulties to oil and gas gathering and transportation and crude oil refining, so dehydration and desalination must be carried out. In order to solve the problems in the process of oil and gas gathering and transportation, a large amount of chemical agents must be used. The chemicals used ...
