Description
Technical field
The utility model relates to a kind of well logging servicing unit, and particularly a kind of hydraulic thrust is by instrument pressure balance bin device.
Background technology
The pressure balance storehouse is the key components that hydraulic thrust leans on instrument, is related to the safety of instrument integral body and the reliability of work.Hydraulic thrust is by being provided with oil pump in the power bin of instrument, and what the power that provides by oil pump was finished instrument opens the receipts leg, and pressure balance stores hydraulic oil in the storehouse, both to the oil pump feed of power bin, and the again variation of the outside mud pressure of perception and offer instrument.
At present, piston type is all adopted in the pressure balance storehouse, and the oil mass of in time replenishing in the instrument internal high and low pressure storehouse with the plunger-type balance mode changes, and realizes the internal and external pressure balance of instrument.The pressure pushing piston motion of mud changes the oil pressure in the balance bunker, but the SDZ-3000 hydraulic thrust leans on the employed piston-type pressure balance bunker of instrument device, and upper cover of piston rod has been equipped with the spring of reset response.Existing SDZ-3000 hydraulic thrust by instrument in production application, the time have instrument to advance the mud accident generation, cause very large economic loss.It is because being that piston-type pressure balance bunker device exists fault of construction, and dynamic storehouse oil pipeline is damaged by pressure by the pressure balance storehouse on top when causing, and build-up of pressure balance sysmte oil starvation causes that instrument internal advances the accident of mud; Sometimes because the spring in the pressure balance storehouse is blocked, make the piston balance sysmte inoperative, cause that instrument internal advances the accident of mud.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, provides a kind of hydraulic thrust simple in structure, reliable operation to lean on instrument pressure balance bin device.
For solving above technical problem, a kind of hydraulic thrust provided by the utility model is by instrument pressure balance bin device, comprise the instrument oil connection, bladder balance bunker and power bin joint, be provided with the tubing interface that is connected with the instrument oil pipe in the described instrument oil connection, the lower end of described power bin joint is connected with power bin and the power bin joint is provided with through hole vertically, the upper pipes muzzle of described bladder balance bunker is contained in the lower end of described instrument oil connection and is tightly connected by clip and instrument oil connection, and the inner chamber of described tubing interface and described bladder balance bunker connects; The lower end mouthpiece cover of described bladder balance bunker is contained in described power bin upper end of joint and is connected with the power bin joint sealing by clip, and the inner chamber of described bladder balance bunker has been filled with hydraulic oil.
With respect to prior art, the utility model has been obtained following beneficial effect: bladder balance bunker is an elastic construction, when being subject to the pressure of outside mud, leather bag can shrink, smaller volume, the hydraulic oil in the leather bag is squeezed simultaneously, transmits the variation of down-hole pressure to instrument; Overall structure is simple, and oil reserve is large, reliable in action, and maintenance and repair is convenient.
As preferred version of the present utility model, the two ends mouth of pipe outer wall of described bladder balance bunker is respectively equipped with the rubber reinforcement sleeve pipe, and described rubber reinforcement sleeve pipe is connected as a single entity with the two ends mouth of pipe respectively, and described clip is stuck in outside the described rubber reinforcement sleeve pipe.The rubber reinforcement sleeve pipe can improve the intensity of the mouth of pipe, can bear the larger pressure of clip, guarantees that sealing reliably and not can damage.
As further preferred version of the present utility model, the middle part outer wall of described bladder balance bunker length direction is provided with the rubber reinforcement sleeve pipe, and described rubber reinforcement sleeve pipe and described bladder balance bunker are connected as a single entity.Outer wall arranges the rubber reinforcement sleeve pipe at the middle part of bladder balance bunker length direction, can improve the intensity of bladder balance bunker.
As further preferred version of the present utility model, described bladder balance bunker is set with protected enclosure outward, and described protected enclosure is provided with and connects the inside and outside mud entrance of case.Bladder balance bunker in the down-hole easily and the borehole wall, rock and metal object rub, rub and can cause when serious bladder balance bunker to damage leakage of oil, protective cover is set after, neither affect the pressure of perception down-hole slurry, play again protective action, prolong application life and the reliability of balance bunker.
