Abstract

The invention discloses a hydrophobic associated polymer containing sulfonating calixarene. The hydrophobic associated polymer is prepared from reaction monomer acrylamide, acrylic acid, vinyl modified sulfonated calixarene and vinyl modified fatty alcohol-polyoxyethylene ether through polymerization reaction. A preparation method comprises the steps that p-tert-butylphenol and formaldehyde are firstly used for preparing p-tert-butyl calix [4] arene, then p-tert-butyl is removed in anhydrous methylbenzene to obtain calix [4] arene, concentrated sulfuric acid is utilized to sulfonate calix [4] arene, and sulfonated calix [4] arene is obtained, methyl acryloyl chloride is utilized to introduce double bonds to the sulfonated calix [4] arene through vinylation, and the vinyl modified sulfonated calix [4] arene performs polymerization reaction with acrylamide, acrylic acid and vinyl modified fatty alcohol-polyoxyethylene ether to prepare the hydrophobic associated polymer containing the sulfonated calix [4] arene. The heat and salt resistance, viscosifying capacity and shearing resistance of the hydrophobic associated polymer containing the sulfonated calix [4] arene are remarkably improved, and the hydrophobic associated polymer has a wide application prospect.

Description

Technical field [0001] The invention belongs to the field of new materials and oil field chemistry, and specifically relates to a hydrophobically associating polymer containing sulfonated calixarene and a preparation method thereof. Background technique [0002] As a non-renewable resource, petroleum is also an important energy and chemical material. Under the condition that my country’s dependence on foreign oil is greater than 50% and the newly discovered large-scale oil fields are few and far between, making full use of existing oil reservoir resources and redevelopment of about 65% of the remaining oil resources after water injection development is to increase crude oil production. A feasible solution for Faced with the phenomenon that my country’s oilfields are in the middle and late stages of exploitation, the injected water points along the high-permeability layer, bypasses the high-oil-bearing areas, a large amount of crude oil is not affected, and the waterflood recovery...
