A temperature-controllable pressure-controlled oil-gas-water-solid multiphase pipeline simulation experiment device

Abstract

The invention provides a temperature-controllable pressure-controllable oil-gas-water-solid multi-phase pipeline simulation device, which is composed of a vacuum pump, a valve, a vacuum gauge, a pressure gauge, a gas flow meter, a vacuum buffer tank, a natural gas compressor, and a visible rotating pipeline , temperature sensor, visual window, gas mass flow controller, reaction kettle, liquid filling pump, liquid storage tank, standpipe, liquid flow meter, gas cylinder, circulation pump, balance, low temperature box, temperature control water bath; the device is divided into It is a gas, liquid, and solid phase supply system, temperature control and heat preservation system, pressure control system, purge and vacuum system, and pipeline flow system. The device can simulate the multiphase flow of oil, gas, water and solid multiphase fluids and gas and liquid single-phase fluids in horizontal, vertical and inclined pipes under certain pressure and temperature conditions. It has simple structure, wide application range and easy operation. The advantage of convenience.

Description

technical field

[0001] The invention relates to a temperature-controllable pressure-controlled oil-gas-water-solid multiphase pipeline simulation experiment device, and relates to the fields of development, storage and transportation of oil and natural gas. Background technique

[0002] In the process of oil and natural gas development and transportation, because the products of oil and gas wells produced are often fluids with coexistence of oil, gas, water and solid media, gas-liquid-solid fluids often appear in horizontal, inclined or vertical pipelines and wellbores. , gas-solid, liquid-solid, liquid-liquid and other multiphase flow states. During the flow process in the pipeline or wellbore, with the change of pressure, temperature and pipeline inclination, phenomena such as slug flow and stratified flow will appear in the pipeline and wellbore, which will cause erosion and corrosion of the pipeline and wellbore, which are serious Threatening the safe operation of pipel...
