Multifunctional thickened oil treating agent and preparation method thereof

Abstract

The invention discloses a multifunctional thickened oil treating agent and a preparation method thereof. The treating agent is prepared from, by weight, 15.35%-17.65% of octanol polyoxyethylene ether, 13.37%-15.54% of lauroyl diethanolamide, 12.66%-15.74% of sodium dodecyl benzene sulfonate, 21.53%-24.57% of odium nonylphenol polyoxyethylene ether sulfate, 8.62%-11.87% of fatty acid methyl ester ethoxylate sodium sulfonate, 0.005%-0.006% of cocamidopropyl betaine, 0.005%-0.006% of cocamidopropyl dimethylamine oxide, 10.00%-15.00% of n-butyl alcohol, 0.001%-0.002% of vitamin A, 0.001%-0.002% of vitamin C and 6.566%-9.037% of water. The multifunctional thickened oil treating agent is an active agent product developed on the basis of tertiary oil recovery and used for increasing the recovery efficiency of an oil field, and the agent is a chemical assistant integrating oil well profile control and displacement, viscosity reduction and coagulation reduction, oil well cleaning and plug removal, and is good in production increasing effect on thickened oil recovery; the advantages of being good in thickened oil recovery oil output increase effect and treatment performance and wide in application range are achieved, and the yield increasing and effect improving functions on multiple kinds of thickened oil and high-viscosity and hypercoagulable oil wells can be achieved by adjusting the formula.

Description

technical field

[0001] The invention relates to a multifunctional treatment agent and a preparation method thereof, in particular to a multifunctional heavy oil treatment agent and a preparation method thereof. Background technique

[0002] For a long time, in the process of oil field tertiary oil recovery development, with the change of formation and crude oil conditions, the application of chemical treatment agents has played an increasingly important role, and at the same time, it faces more complicated problems. At present, in the treatment of heavy oil wells, due to the limitations of raw materials and formulations, the existing chemical treatment agents often have a single product type in field application, poor performance in temperature resistance, salt resistance, and salinity resistance, and crude oil processing capacity Poor, unsatisfactory treatment effect on heavy oil, etc. In addition, it is difficult to provide effective technical support in the production pr...
