The multifunctional fluid annular channel experiment device adjusts the valves to open or close to change the process of experiments, and is flexible to operate and strong in adaptability. Main equipment and a meter are high in utilization rate.

Description

technical field [0001] The invention relates to a multifunctional experiment fluid circuit experiment device. Background technique [0002] Crude oil produced by most oilfields in my country is heavy oil and waxy oil. During the production process, the oilfield produced fluid mostly exists in the form of oil-water two-phase flow or oil-gas-water three-phase flow. During the gathering and transportation process, oil-water mixed transportation or oil-gas-water Mixed process. In the process of crude oil extraction and transportation, any changes in thermal effects, force effects, electrical effects or other physical and chemical factors may cause changes in the deposition of heavy organic matter in the produced fluid and its flow characteristics. The rheological properties and viscosity-temperature properties of crude oil and its produced fluid are the key physical parameters in the process design of oil pipelines. The solid-phase deposition evaluation of heavy organic substanc...

AI Technical Summary

Problems solved by technology

For example, many research centers at home and abroad have successively established various loop experimental devices for experimental research on fluid pipeline characteristics, waxy oil wax deposition characteristics, waxy oil shutdown and restart, two-phase flow and multi-phase flow, etc. Some of these devices have relatively simple test and analysis functions, limited test range, and complicated operations

For loop test devices with specific functions, the corresponding engineering and technical problems can often be solved well, but once the test fluid type, test scheme, and test conditions change, such devices are difficult to adapt, and large-scale transformation or reconstruction must be carried out , the utilization rate of main equipment is low
