Abstract

The invention relates to a high-pressure oil-gas-water pipe wax-flowing deposition simulation experimental device, which includes a loop system, an oil supplying system, a gas supplying system, a measurement system, a temperature controlling system and a data collecting system. The loop system comprises a test section and a reference section, and is used for a wax deposition experiment; the oil supplying system is used for providing testing oils for the loop system; the gas supplying system is used for providing high-pressure gases for the oil supplying system; the measurement system is used for testing status data of all pipelines; the temperature controlling system is used for controlling temperatures of the loop system and the oil supplying system; and the data collecting system is usedfor collecting and dealing the status data, computing a pipe diameter of a pipe after inner pipe wax deposition in the test section, and obtaining the average thickness of wax deposition layers and the wax deposition rate.

Description

technical field [0001] The invention relates to a high-pressure oil-gas-water pipeline flow wax deposition simulation experiment device, and relates to the technical field of multi-phase mixed transportation pipeline wax deposition simulation experiments. Background technique [0002] At present, wax deposition in multi-phase mixed transportation pipelines has brought great challenges to the development of multi-phase mixed transportation technology. It is urgent to explore the rules of multi-phase flowing wax deposition, establish a multi-phase wax deposition model, and predict the thickness of wax deposition in pipelines. The pigging scheme provides a theoretical basis. [0003] A number of experimental devices have been built in the existing technology, the main representatives are: the French Petroleum Research Institute Lyre wax deposition experiment ring, the total length is 152.4m, the inner diameter is 50.8mm, the wax deposition section is 7.01m long, the working pre...
