Problems solved by technology
For example, when simulating an underground high temperature and high pressure environment, the state comparison of the fluid before and after passing through the choke is compared. However, the currently disclosed device cannot observe the situation before and after the throttle of different chokes in different working environments. By installing multiple sensors in the device Detection data; however, it is not possible to observe intuitively, and at the same time, the working environment cannot be changed, so that the simulation device cannot observe the throttling state in different working environments

The invention relates to a visualized throttling experiment device, and the device comprises a pedestal, a lower glass tube, a connecting part, an upper glass tube, a transparent temperature-resistant and pressure-resistant glass tube, a plastic part, and a heating glass cover. The lower end of the connecting part is connected with the upper end of the lower glass tube, and the upper end of the connecting part is connected with the lower end of the upper glass tube. The interior of the connecting part is provided with the transparent temperature-resistant and pressure-resistant glass tube, and the transparent temperature-resistant and pressure-resistant glass tube is communicated with the lower and upper glass tubes. The interior of the transparent temperature-resistant and pressure-resistant glass tube is of a hollow structure with the T-shaped profile. The plastic part is cooperatively installed in the T-shaped hollow structure, and the interior of the plastic part is axially provided with a small hole. A side surface of an adapter is provided with an opening, and the opening is connected with a gas-liquid discharge pipe, wherein the gas-liquid discharge pipe is provided with a transparent valve for controlling the size of a back pressure. The device is advantageous in that the device can visually observe an experiment process, and can achieve the replacement of throttle devices in different sizes or with different apertures, so as to observe the throttling phenomena of different throttle devices under different experiment conditions.
Description
[0001] A visual throttling experimental device technical field [0002] The invention relates to an experimental device, in particular to a visual throttling experimental device. Background technique [0003] In order to control the production of gas wells, throttling technology is usually used, and in order to make the gas flow temperature after throttling higher than the initial temperature of hydrate formation under the pressure condition after throttling, to reduce the pressure of surface pipelines and reduce the cost of gas well production, downhole throttling is usually used. Therefore, the wellbore flow state and liquid-carrying analysis of downhole choke gas wells are key technologies in gas well production, which directly affect the rationality of gas well production system and ultimate recovery. [0004] Throttling is a phenomenon in which the fluid flows in the pipeline and suddenly encounters a narrowing of the cross section, which causes the pressure to drop. D...
