Dynamic simulation and evaluation device for chemical paraffin remover and evaluation method

Abstract

The invention relates to a dynamic simulation and evaluation device for a chemical paraffin remover and an evaluation method. According to the technical scheme, an experiment simulation pipeline is fixed in an inner cavity of a constant-temperature water bath through a pipeline fixing bracket, the lower end of the experiment simulation pipeline is connected to a piston pump, and the piston pump is driven by a motor and connected with a sample tank; a liquid drainage pipe is connected to the upper end of the experiment simulation pipeline, a liquid drainage port plug valve is arranged at the tail end of the liquid drainage pipe, and a recovery tank is arranged below the liquid drainage port plug valve. The dynamic simulation and evaluation device has the benefits as follows: pressure, temperatures, flow, the flow speed and the like can be adjusted and controlled by means of the experiment simulation pipeline to simulate the dynamic process of petroleum and the paraffin remover in the pipeline; a pipe diameter, wax precipitation composition and other parameters are adjusted, the actual technological parameters in the field application process are simulated, dynamic simulation and evaluation of the paraffin remover are realized, the field application effect of the paraffin remover is relatively directly reflected, and the research time of the paraffin remover is shortened.

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.
