PRODUCT DESCRIPTION
A water-base antiwax inhibitor for oil-gathering or oil-displacing wells in oil field contains wax crystal improver, disperser, cosolvent, surfactant and water. Its advantages are high safety, high antiwax and pour-inhibiting effect, and low setting point (-35 deg.C).
The present invention relates to a drug used in oilfield engineering, especially in polymer flooding wells produced fluid used in medicine, is a water-based polymer flooding wells Paraffin agent.
The invention is based on water as the dispersion medium, a surfactant and a water-soluble wax crystal modifiers as a main component, no fire and explosion factors, safe and reliable; amphiphilic surfactant molecules adsorbed metal or wax crystal surface tubing, rod, etc., are arranged is formed adsorption layer oriented, reduce the interfacial free energy, which can effectively change the wettability of the solid surface, the surface was hydrophilic nature, so that subsequent precipitation from the crude oil The wax crystals is not easy to be attracted and deposited on these surfaces and, therefore, can achieve the purpose of the anti-wax. And to promote the well produced fluid in the W / O type emulsion into an O / W emulsion, oil viscosity has dropped significantly, reaching viscosity purpose; Paraffin agent in addition to the heavy, generally greater than 0.95 for high The aqueous crude oil from the well casing can join and easy to sink to the bottom, Paraffin good effect, pour point below -35 ℃, suitable for cold weather use.
APPLICATION METHOD
(1) Increase the use of dosing pumps or bottles of medicine will Paraffin agent continuously or intermittently adding the oil wells set of annular space.
(2) Continuous dosing of liquids production of 0.01to 0.05%
(3) Intermittent dosing for each of the 25~200kg, 7~15 day cycle
PACKAGE
(1) 25kg plastic drum or 200kg metal pail.
(2) Non-dangerous goods transport. Stored in the cool air, the effective storage period is one year.
