Problems solved by technology

All of these affect the accuracy of the loop simulation, and a large amount of physical and mathematical processing must be performed on the processing and amplification of the test data to correct it. Therefore, using the loop to simulate the wax deposition process is cumbersome and has disadvantages

Abstract

The invention provides a high-pressure sealing circulatory imitating wax deposition device for wax deposition imitation in long petroleum pipeline. It comprises a sealing kettle (26) which has an oil inlet (15) and an oil outlet (27), an electric stirrer (23) inserted in kettle (26), a temperature-control and a detector. The temperature-control has an inner heater which is fixed on the stirrer (23) and inserted in the kettle (26), a clamping sheath (4) which covers the inner container (6), a heat-insulating layer (3) and an outer cover (2). The detector comprises a piezometer (10) which is inserted in the kettle (26) through the kettle cover (7), a plurality of temperature sensor (21-2) in the kettle (26), a temperature sensor slideway (14), a plurality of temperature sensor drive pipe (20) which is through the outer cover (2), heat-insulating layer (3), clamping sheath (4) and close to the outer wall of inner container (6). Said simulator has small structure, volume, little apparatuses, large experiment space of oil sample, while the equivalent sheared intensity of oil sample equals the intensity of on-site oil of channel in the simulating experiment that the geometrical and dynamical condition is close to the on-site reality. The experiment has real simulating course, accurate data, and lower cost.

Description

technical field [0001] The invention relates to a high-pressure sealing circulation type wax deposition simulation device used for wax deposition simulation of long-distance crude oil pipelines. It relates to the technical field of piping systems. Background technique [0002] The wax deposition in the long-distance crude oil pipeline seriously affects the safe and economical operation of the pipeline. It is of great significance for pipeline operators to know the wax deposition in the pipeline. At present, the oil transportation site mainly calculates the average wax deposition thickness between stations through the inverse calculation of the pressure drop between stations. Since the operating parameters of the pipeline are often fluctuating, the accuracy of the wax deposition data obtained by this method is not high, and it cannot reflect the internal pressure of the pipeline. Realistic wax distribution. Another method is to use an indoor simulation device to predict the...
