Abstract
The invention relates to a preparation method of a polymer-containing emulsified crude oil emulsion breaker. According to the conventional field-developed emulsifying oil, great difficulty is caused to an original emulsion breaker technology, emulsion breaking and dehydration of crude oil are incomplete, difficulty in running a large precipitating tank is caused since a part of polymers enter the large tank, and normal handover of crude oil is influenced severely. The method comprises the following steps of: adding water and an emulsifier OP-10 into a four-hole flask; stirring to mix uniformly; adding a potassium persulfate aqueous solution; raising the temperature to 80 DEG C, and stirring for 10 minutes; continually dropwise adding polyamine polyoxypropylene polyethenoxy ether, alkyl phenolic resin polyoxypropylene polyethenoxy ether and polyethylene polyamine polyoxypropylene polyethenoxy ether; adding an FC-N01 fluorocarbon surfactant; adding methanol serving as a solvent; lowering the temperature to 60 DEG C; and stirring at constant temperature for 1 hour to obtain a finished emulsion breaker. By adding a 50-80 mg/l of crude oil produced liquid emulsion breaker prepared with the method when the dehydration temperature of crude oil is 30-45 DEG C, the water content of dehydrated crude oil is smaller than 0.2 percent, and the oil content of sewage is smaller than 500 mg/l.
Description
Technical field
The present invention relates to a kind of preparation method who contains polymer emulsified crude oil demulsifier.
Technical background
Long celebrating oil field is through 40 years of development; Developed into tertiary oil recovery technology at present; The characteristics of TOR are injected oil-displacing agent to oil reservoir exactly and are recovered the oil, and as in oil reservoir, injecting hot steam, inject surfactant system, injection of polymer solution, inject alkaline solution etc., and polymer flooding is to be a kind of method that improves RF of oil-displacing agent with the aqueous solutions of polymers at present; Be one and improve RF; Increase the important technical of crude production rate, therefore, the anionic hydro-polyacrylamide that relative molecular mass is high is widely used as the TOR auxiliary agent.But along with the application of polymer technology in highly aqueous field, polymer content increases thereupon in the extraction liquid.When polymkeric substance existed in extraction liquid, aqueous viscosity increased on the one hand, and more on the other hand polymkeric substance is adsorbed to the water-oil interface place, made the stability of emulsion of crude oil increase, and it is difficult that breakdown of emulsion becomes.Therefore, to the influence that the polymkeric substance that contains in the crude oil emulsion causes breakdown of emulsion, it is to solve to improve the emulsion splitter integrated application that exploitation contains polymer emulsified crude oil demulsifier, solves the key of on-the-spot oil in water emulsion breakdown of emulsion and self-cleaning oil handing-over.Recover the oil two factories, the units such as three factories, four factories that recover the oil of long celebrating oil field all adopt polymer displacement of reservoir oil tech at present in a large number; But the on-the-spot oil in water emulsion of finding causes very big difficulty to original emulsion splitter is technical; The joint station crude oil demulsification dehydration of part oil recovery factory is not thorough; Partial polymer gets into big jar of sedimentation, causes big jar of operation difficulty, has had a strong impact on the normal handing-over of crude oil.
Summary of the invention
