Description
Technical field
It the utility model is related to oil drilling downhole instrument operation instrument, more particularly to a kind of rotary valve slurry pulsator
Taking-up instrument.
Background technology
At present, directional well has become a kind of important means of exploitation, rotary valve mud arteries and veins in petroleum exploration and development process
Device is rushed to have been widely used in directional well as a kind of important downhole instrument for realizing drilling well orientation construction.Using rotary valve
It is that rotary valve pulser is arranged on without in magnetic hanging pup joint and circumferentially solid with holding screw during slurry pulsator orientation construction
It is fixed, it is oriented construction with drilling tool G.I.H.Due to the influence of mud solid concentration or loss circulation material, usually cause rotary valve
Slurry pulsator is stuck in no magnetic hanging pup joint and can not taken out, and particularly is less susceptible to take out after the mud in gap is dried.It is existing
In the construction of field, supporting drawing device can only use when rotary valve slurry pulsator does not block firm completely, once card jail uses drawing
Instrument is pulled out, the situation that drawing device is pulled off and failed with rotary valve slurry pulsator coupling part usually occurs, can only be from brill
Well scene returns to maintenance worker-house, is ejected using upper deduction by card pulser.Not only maintenance cycle is grown, and adds cost of transportation
And the labor intensity of operating personnel.
The content of the invention
In order to solve rotary valve slurry pulsator no magnetic is stuck in using the rear influence because of mud solid concentration and loss circulation material
The problem of can not being taken out in hanging pup joint, the utility model provide a kind of rotary valve slurry pulsator and take out instrument, the instrument
It is easy to carry, installs, can be used as the kit of rotary valve slurry pulsator site operation, it is time saving and energy saving, it can reduce again
Orient construction cost.
The utility model is realized by using following technical proposals：
A kind of rotary valve slurry pulsator takes out instrument, it is characterised in that：It is mainly by extension nipple, double female pipe nipples, interior
Connecting tube, hydraulic cylinder and manual pump group are into extension nipple is solid with being connected with rotary valve slurry pulsator without magnetic hanging pup joint
Fixed, double female pipe nipples are connected with extension nipple, and the inner connection tube is enclosed on rotary valve slurry pulsator, the hydraulic cylinder and
Double female pipe nipples are connected, and manual pump is connected by flexible pipe with hydraulic cylinder.
Described double female pipe nipples are manufactured using aluminium alloy and are provided with piston observation groove, are easy to observation to eject hydraulic cylinder when operating
The position of piston.
The inner connection tube welds cylindrical plug using dimension tubing and formed, and is enclosed on rotary valve slurry pulsator
On.
And then reduce the processing cost of inner connection tube.
The utility model device is in use, a kind of rotary valve slurry pulsator takes out instrument and carries rotary valve mud-pulse
After being connected without magnetic hanging pup joint of device, hydraulic cylinder is promoted using manual pump, hydraulic cylinder piston is withstood the bottom of inner connection tube
Portion, upward thrust is passed into rotary valve slurry pulsator, ejects rotary valve slurry pulsator upwards using hydraulic thrust.Root
According to the stroke of hydraulic cylinder piston, can the multiple different length specifications of accessory processing extension nipple, the length difference of each extension nipple
For the stroke of piston.After hydraulic cylinder piston all ejects, hydraulic thrust is laid down, changes shorter extension nipple, repeat to push up
Rotary valve slurry pulsator, until ejecting rotary valve slurry pulsator completely.
Compared with prior art, what the utility model was reached has the beneficial effect that：
The taking-up tool operation is simple, is easy to carry, in site operation once occur rotary valve slurry pulsator it is stuck
During without in magnetic hanging pup joint, the exclusion of failure can be quickly realized, it is not necessary to maintenance worker-house is returned to, time when effectively reducing non-brill,
Improve instrument service efficiency.
