A dynamic simulation evaluation device and evaluation method for chemical wax remover

Abstract

The invention relates to a dynamic simulation evaluation device and evaluation method for a chemical wax remover. Its technical scheme is: the inner cavity of the constant temperature water bath tank fixes the experimental simulation pipeline through the pipeline fixing bracket, the lower end of the experimental simulation pipeline is connected to a piston pump, the piston pump is driven by a motor, and the piston pump is connected to the sample tank; the experimental simulation The upper end of the pipeline is connected with a liquid discharge pipe, the end of the liquid discharge pipe is provided with a liquid discharge port cock valve, and a recovery tank is provided below the liquid discharge port cock valve. The beneficial effects are: the present invention can realize the adjustment and control of pressure, temperature, flow rate, flow rate, etc. by setting the experimental simulation pipeline, and simulate the dynamic process of petroleum and wax remover in the pipeline; adjust the parameters such as pipe diameter and wax composition, Simulate the actual process parameters in the field application process, realize the dynamic simulation evaluation of the wax remover, more intuitively reflect the field application effect of the wax remover, and shorten the development time of the wax remover.

Description

technical field [0001] The invention relates to an application evaluation technology of a chemical wax remover, in particular to a dynamic simulation evaluation device and evaluation method of a chemical wax remover. Background technique [0002] Crude oil mostly contains wax, colloid, and asphaltenes, and belongs to high-condensation and high-viscosity crude oil. Waxes, colloids and asphaltenes in crude oil begin to precipitate at a certain temperature, pressure, and flow rate, and deposit on the inner surfaces of equipment such as pipelines, valves, separators, and storage tanks, increasing flow resistance and energy consumption, and reducing crude oil Production and pipeline transportation production, in severe cases, may cause accidents such as pipeline blockage, pump jamming, sucker rod jamming, etc. Therefore, it is necessary to frequently carry out wax removal and anti-wax construction on pipelines and oil well pipes. At present, mechanical, thermal, chemical, microb...

AI Technical Summary

Problems solved by technology

[0004] Both static and micro-dynamic evaluation devices and methods cannot effectively simulate the dynamic process of wax remover in the application process, which makes the indoor research evaluation and field application conditions have static and dynamic differences.
