Problems solved by technology
[0002] At present, whether the downhole pulsator pumps oil is good or bad directly affects the work of the pulsator, and the pulsator needs a long time of vacuuming and oil flushing, and the work depends on the piston to pump and discharge oil, so the sealing of the piston inner cavity is extremely important During well logging, because the pulse generating device is in a mud environment as a whole, the mud contains particles of different sizes, and these particles can easily enter the power piston of the pulser and damage the sealing ring and sealing surface
This will easily lead to poor sealing, and it is necessary to stop production and carry out maintenance, which seriously affects normal work, affects work efficiency, and increases maintenance costs.

Description
technical field [0001] The invention specifically relates to a pulse generator protection device. Background technique [0002] At present, whether the downhole pulsator pumps oil is good or bad directly affects the work of the pulsator, and the pulsator needs a long time of vacuuming and oil flushing, and the work depends on the piston to pump and discharge oil, so the sealing of the piston inner cavity is extremely important During well logging, because the pulse generating device is in the mud environment as a whole, the mud contains particles of different sizes, and these particles can easily enter the power piston of the pulser and damage the sealing ring and sealing surface. This easily leads to lax sealing, which requires production to be stopped and repaired, which seriously affects normal work, affects work efficiency, and increases maintenance costs. Contents of the invention [0003] The object of the present invention is to provide a protection device for a pu...
