Description
Technical field
The utility model relates to a kind of circulating sleeve extraction device, particularly a kind of downhole drill circulating sleeve withdrawing device.
Background technology
Orientation joint assembly is one of chief component of MWD instrument, be connected to non magnetic drill collar lower end, seat key and mud pulse signal for MWD instrument produce, due to slurry erosion and reason such as wearing and tearing collision etc., orientation joint easily damages often, and circulating sleeve inside being arranged on is intact available, because circulating sleeve price is higher, when scrapping and keep in repair orientation joint, circulating sleeve need to be taken out to recycling.
The method of taking out at present circulating sleeve is to back out after positioning bolt, and joint pin thread is upwards stood on the ground, and diameter and sizeable iron are put into joint, the hand steered iron of a people, and a people is pounded out with hammer.Because silt fills and the outer sealing ring crimp of circulating sleeve, circulating sleeve is difficult to take out, and wastes time and energy, and the personnel that easily cause injure, dangerous large, and the circulating sleeve taking out often smashes; Also have in addition a lot of circulating sleeves to pound out, orientation joint and circulating sleeve can only together with scrap, cause the wasting of resources.
Chinese patent literature number: CN 202970563 U, patent name < < orientation joint circulating sleeve special-purpose taking goes out instrument > >, comprises drawing axle, is arranged on the hydraulic cylinder on drawing axle; Described drawing axle lower end is passed the endoporus of the hydrophthalmia of orientation joint and the circulating sleeve of orientation joint inside successively; On described drawing axle and hydraulic cylinder top position section hammering piece is installed.This device takes out circulating sleeve by manual shock hammering piece, wastes time and energy, and the personnel that easily cause injure, dangerous large.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of light and handy convenience is provided, simple to operate, safe and reliable downhole drill circulating sleeve takes out instrument, be installed at the scene on orientation joint, by hand, make hydraulic mandril eject circulating sleeve, a people can complete independently, avoid pounding out with hammer the dangerous approach of circulating sleeve, can avoid smashing circulating sleeve, reach both safety, again cost-saving object.
Its technical scheme is: comprise fixed support, screw hydraulic top, the first support bar, the second support bar, orientation joint, fixed support is hollow structure, support bracket fastened lower end is taper sheath, the inside of taper sheath is provided with internal thread, the top of orientation joint is provided with the taper joint matching with fixed support, orientation joint bottom is circulating sleeve, circulating sleeve top is fixed by the second support bar, the first support bar connects the second support bar, the socket screw hydraulic top, top of the first support bar, described screw hydraulic top comprises nut block, screw rod, cavity, rotating handles, nut block is fixed on the top of cavity, described nut block and screw rod pass through threaded engagement, screw rod laterally connects rotating handles, match with the external screw thread of orientation joint in the bottom of described cavity.
The upper end of above-mentioned orientation joint is provided with the annular protrusion matching with the first support bar.
The beneficial effects of the utility model are: this instrument is installed to after orientation joint pin thread, one people can be pushed up circulating sleeve is taken out by screw hydraulic, avoided an original people to help, the dangerous approach that one people is pounded out circulating sleeve with hammer, effectively raises efficiency and integrity that MWD circulating sleeve takes out, has reduced staff's labour intensity and danger, simple to operate, safe and reliable, lightly convenient, be easy to carry and on-the-spot application.
Accompanying drawing explanation
