Composite acidizing fluid injection device for oil field oil-water well

Номер: CN116291347A
Автор: ZHANG CUIJIE, ZHU XIANGHUI
Принадлежит:

The invention belongs to the technical field of oil-water well composite acidizing fluid injection, and relates to an oil field oil-water well composite acidizing fluid injection device. The device comprises a shell, a liquid inlet is formed in the upper end of the shell, and a liquid outlet is formed in the lower portion of the shell. A stirring mechanism is rotationally arranged in the shell, and the liquid outlet is communicated with the injection mechanism. And the piston reciprocates up and down in the first straight pipe, so that the composite acidizing fluid is alternately fed into and discharged from the second straight pipe. And by controlling the second motor, the volume of the composite acidizing fluid injected into the oil-water well can be controlled, and the situation that the acidizing treatment effect is affected due to excessive or too little use of the composite acidizing fluid is avoided. The composite acidizing fluid inside and outside the guide cylinder forms circular ...

Vibration-damping drilling machine for oil exploitation

Номер: CN116163655A
Автор: ZHANG CUIJIE, ZHU XIANGHUI
Принадлежит:

The invention belongs to the technical field of oil exploitation, and relates to a vibration-damping drilling machine for oil exploitation. The device comprises a mounting frame and a drilling machine mechanism, a connecting plate is vertically and slidably connected to the mounting frame, and a first connecting sleeve is rotatably mounted on the connecting plate. The drilling machine mechanism comprises a driving assembly, a drill rod and a drill bit. In the drilling process of the drill bit, along with rotation of the first connecting sleeve, the driving assembly drives the piston plate to move up and down in a reciprocating mode, the piston plate enables the firing pin to move up and down in a reciprocating mode through liquid, the firing pin continuously impacts the baffle, the drill bit vertically vibrates, and rocks are vibrated and broken. And meanwhile, liquid flows to the drill bit through the liquid channel to cool the drill bit, so that the drill bit is prevented from being easily ...
