Binary copolymerized anticrustator synthesis technology based on control of stirring time

Abstract

The invention discloses a binary copolymerized anticrustator synthesis technology based on control of stirring time. The synthesis technology comprises steps of (a) firstly preparing chelated group monomer and acrylamide according to a certain proportion; (b) adding the chelated group monomer and acrylamide into a reaction vessel, then adding a solvent to be dissolved, and adding a catalyst; (c) stirring so as to mix fully and uniformly; (d) putting into water bath, stirring for 30-50 minutes at certain temperature, and reacting so as to obtain a reaction product mixture; (e) cooling the reaction product mixture and filtering, distilling the filtered liquid at reduced pressure, and separating so as to obtain the target product. The synthesis technology can successfully synthesize binary copolymerized anticrustator, the synthesized binary copolymerized anticrustator has excellent property, the synthesis steps are simple, the synthesis cost is low, and the conversion rate of the reaction and the antiscaling performance of the target product are improved by controlling the stirring time in reaction process.

Description

technical field [0001] The invention relates to a synthesis process of binary copolymerization antifouling agent based on controlling stirring time. Background technique [0002] During the development of oil and gas fields, the fluids (oil, gas and water) in the oil and gas reservoirs flow out from the formation, through the wellbore and wellhead to the surface gathering and transportation system, due to changes in temperature, pressure and other conditions, as well as the thermodynamic instability and chemical Incompatibility leads to the destruction of oil-gas-water balance. It often causes fouling in water injection formations, oil casings, downhole, surface equipment, and gathering and transportation systems. Scaling has a great impact on the normal production of oil wells. When scales are deposited on equipment such as well bores, oil pipes, oil well pumps, water injection systems, gathering and transportation systems, heating systems, etc., the equipment will not ope...

Descaling is a remedial measure. During descaling, it has already resulted in reduced production and corrosion of equipment, resulting in large economic losses. Therefore, preventing the formation of scale is a good measure
