Device and method for outputting high frequency pressure pulse

Abstract

The invention provides a device and method for outputting a high frequency pressure pulse and relates to the technical field of fluid pressure executing devices, and solves the technical problem of improving a passel output frequency and a pulse pressure at the same time. A high frequency pulse communication module and an upper computer of the device are connected by way of multi-thread control, adriving gas source is connected to an air inlet of a two-position five-way valve, two gas circuit outputs of the two-position five-way valve are connected to an air cylinder joint of a high frequencypulse pneumatic valve, an inlet of the high frequency pulse pneumatic valve is connected to a pressure regulating valve, and the pressure regulating valve is connected to a power source. By improvingthe structure of the pneumatic valve, the gas response speed is improved. By improving the high frequency pulse communication module, the action frequency can be further replaced while high frequencyaction is ensured. In addition, electromagnetic control and pneumatic control are combined by means of the device to output the high frequency pressure pulse and a gas path is further expanded, so that mounting positions of an electromagnetic valve and a pneumatic valve can be separated to the maximum extent and the action frequency is not affected.

Description

technical field [0001] The invention relates to the technical field of fluid pressure actuators, in particular to a device for outputting high-frequency pressure pulses and a method for outputting high-frequency pressure pulses using the device. Background technique [0002] In the research of oil exploitation, hydraulic slapping is often used to modify the physical properties of the reservoir, improve the sweep coefficient and improve the recovery factor. When carrying out relevant mechanism research in the laboratory, due to the lack of reliable methods and devices that can output liquid pulses and gas pulses at high frequencies, the adjustment range of experimental parameters is limited. In addition, the devices that output high-frequency pressure pulses often need to replace accessories. At present, the commonly used electromagnetic valves usually use electromagnets to cooperate with flat or conical surfaces to seal. In order to meet high pressure conditions, springs wit...

Problems solved by technology

When conducting relevant mechanism research in the laboratory, due to the lack of reliable methods and devices that can output liquid pulses and gas pulses at high frequencies, the adjustment range of experimental parameters is limited. In addition, the devices that output high-frequency pressure pulses often need to replace accessories

At present, the commonly used electromagnetic valves usually use electromagnets to cooperate with flat or conical surfaces to seal. In order to meet high pressure conditions, springs with sufficient rigidity are used to apply pretightening force. It is easy to produce permanent deformation and affect the life of the valve

In addition, when conducting flammable and explosive gas tests, the solenoid valve cannot meet the safety requirements
