Abstract

The invention provides a high-pressure wax deposition simulation device and method. The high-pressure wax deposition simulation device comprises a high-pressure kettle (1), wherein the high-pressure kettle (1) is internally provided with a cold finger (5) used for wax deposition; the temprature of the cold finger (5) is controlled by a first temperature control system (18); the temperature in the high-pressure kettle (1) is controlled by a second temperature system (19); the high-pressure wax deposition simulation device further comprises a sampling pipe (9), a sampling device (21) and a visible window (10), which can be used for sampling and observing under a high-pressure environment in the high-pressure kettle (1); and the high-pressure wax deposition simulation device further comprises a viscosity detection device (17). The high-pressure wax deposition simulation device and method provided by the invention can realize wax deposition simulation experiment, viscosity online detection and visualization processes under the high-pressure environment.

Description

technical field [0001] The invention relates to the field of oil and gas storage and transportation test equipment, in particular to a high-pressure wax deposition simulation device and a high-pressure wax deposition simulation method. Background technique [0002] With the exploitation of deep sea oil and gas resources, submarine pipeline transportation is an important link. Deep-sea oil and gas pipelines mostly adopt oil-gas-water multiphase mixed transportation technology. The pipelines are located in the high-pressure and low-temperature seabed environment, which easily leads to the formation of hydrates and hydrate slurry during the transportation process. Some seabed crude oil is waxy, waxy crude oil may have wax deposition process during the submarine pipeline transportation, and the influence of hydrate on the wax deposition process is an important part of the study of waxy crude oil seabed transportation. At present, there are many experimental devices for studying...
