Problems solved by technology
In the existing gas well erosion experiments, the test liquid is often sprayed onto the sample by using a high-pressure nozzle, and the fluid forms an injection zone on the sample. However, this injection zone is often difficult to meet the preset precise requirements, so it cannot A good study of the impact of incident angle on erosion, the accuracy of the experimental results needs to be improved

The embodiment of the invention provides a gas well erosion experimental system, an erosion method thereof and a flow beam adjusting device. The gas well erosion experimental system comprises a high pressure nozzle and an erosion chamber, wherein the flow beam adjusting device is arranged between the high pressure nozzle and the erosion chamber; the flow beam adjusting device comprises an upper vertical baffle and a lower vertical baffle which are located in a same plane; and at least one of the upper vertical baffle and the lower vertical baffle is capable of longitudinally moving and positioning, so that an erosion gap meeting the preset requirement can be formed between the upper vertical baffle and the lower vertical baffle. According to the gas well erosion experimental system provided by the embodiment of the invention, more accurate jet drop point control can be realized, so that the variation range of the included angle between the fluid injected onto an experimental sample and the experimental sample is ultra small and can be regarded as an angle, and the purpose of accurately controlling the angle of incidence can be achieved by adjusting the angle between the injected fluid and the experimental sample.
Description
technical field [0001] The present application relates to the technical field of gas well erosion, in particular to a gas well erosion experiment system, an erosion method, and a flow regulating device. Background technique [0002] At present, the size design of gas wells and injection-production well strings should first meet the requirements of gas well proration and injection-production well gas production volume, and at the same time, factors such as pressure loss along the process, critical liquid-carrying flow rate and critical erosion flow rate should be considered comprehensively; among them, Critical erosion flow rate is an important factor limiting the size of production string and injection-production string. The size of the production string and the injection-production string should not be smaller than the string size corresponding to the critical erosion flow rate; otherwise, the string is prone to erosion, resulting in failure of the string; on the contrary, ...
