The invention relates to a biochemical composite paraffin removal and inhibition agent and application, and belongs to the technical field of paraffin removal and inhibition of oil wells, the biochemical composite paraffin removal and inhibition agent is prepared from the following components by weight: 20-30 parts of a
lipopeptide biosurfactant, 8-15 parts of
alkyl dimethyl carboxyl
betaine, 3-5 parts of a
demulsifier, 2-5 parts of cocoanut
fatty acid diethanolamide, and 45-67 parts of water. The
wax-proof
viscosity-
reducing agent has good
wax-proof
viscosity-reducing effects on high-
wax-content
crude oil; the paraffin inhibition rate is more than 80%, and the
viscosity reduction rate is more than 65%; the interfacial tension and the
wetting reversal effect can be effectively reduced, and the
permeation and dispersion properties are relatively strong; the
system is wide in application range, is suitable for the formation temperature range of 30-120 DEG C, is suitable for the surface
crude oil viscosity of below 1000 mPa.s, is suitable for the produced
liquid water content of more than 20%, and is suitable for the formation
working fluid level of more than 300 m; the average alternating load can be reduced to a greater extent, and the average alternating load of the biochemical composite paraffin remover and inhibitor can be reduced by more than 60% at most in site construction; the components of the
system are biodegradable products and have the characteristics of being green, non-toxic,
pollution-free, free of organic
chlorine, safe, environment-friendly and the like.
