The invention belongs to the field of
petroleum drilling and production. The invention particularly relates to a hydraulic high-pressure particle jet plug drilling test device. The device comprises aconveyor, a cementing
truck, a high-
pressure pipe, a skid-mounted frame, a sliding sleeve, a movable cross beam, a vertical rail, a sliding sealing
assembly, a return pipeline, a balancing weight, anupper glass cylinder, an oil
pipe, a spray head, a
nozzle, a lower glass cylinder, a hinge, a
recovery tank and the like, the special particle jet drilling and plugging test device is used, the groundfull-size
simulation of the underground particle jet drilling and plugging process is realized; by means of
visualization of particle
jet flow jet drilling and annulus upward returning, lowering andlifting of a spray head can be effectively controlled, due to adjustable bit pressure in the drilling process and reliable dynamic sealing of a moving oil
pipe and annulus return liquid, the hydraulichigh-pressure particle
jet flow plug drilling effect is verified, and hydraulic high-pressure particle
jet flow plug drilling optimization construction parameters are obtained.
