A nano-composite high-wax heavy oil pour point and viscosity depressant and preparation method thereof

Abstract

The invention provides a nano-composite high-wax heavy oil pour point and viscosity reducer and a preparation method thereof. The pour point and viscosity reducer includes the following components: nano silicon dioxide, silane coupling agent, stearyl methacrylate, Maleic anhydride, styrene and acrylamide; the mass volume ratio of nano-silica to silane coupling agent is 2-3:1g / mL, and the molar ratio of octadecyl methacrylate, maleic anhydride, styrene and acrylamide is 3-8:1:2:1; the molar volume ratio of octadecyl methacrylate to silane coupling agent is 3-8:1mol / mL. The invention also provides a preparation method of the pour point and viscosity reducer. The pour point depressant and viscosity depressant of the present invention has the effect of depressing the pour point and viscosity at the same time, and the effect is good, the low temperature fluidity of crude oil is improved, the production process is simple and easy to control, and it effectively solves the problem that the pour point depressant and the viscosity depressant cannot be taken into account at the same time. Problems such as poor fluidity at low temperature have broad application prospects.

Description

A kind of nano composite material high wax heavy oil pour point and viscosity reducer and preparation method thereof technical field The present invention relates to pour point depressant and preparation technical field thereof, be specifically related to a kind of nano composite material high wax heavy oil pour point depressant Viscosity reducer and preparation method thereof. Background technique With the continuous exploitation of petroleum resources, the reserves of light crude oil are rapidly decreasing, and unconventional oil and gas resources such as heavy oil are rapidly decreasing. sources are getting more and more attention. Heavy oil is an important part of the world's oil and gas resources. The complex composition makes heavy oil density, viscosity and viscosity. At room temperature, heavy oil is solidified and has extremely poor fluidity. Therefore, the exploitation of heavy oil and Shipping is a huge problem. How to effectively transport heavy oil wi...
