Abstract
The utility model discloses an extracting tool special for an orientation sub loop sleeve. The extracting tool special for the orientation sub loop sleeve comprises a drawing shaft, and a hydraulic cylinder arranged on the drawing shaft, wherein a lower end of the drawing shaft sequentially penetrates through a water hole of an orientation sub and an inner hole of the loop sleeve in the orientation sub; a hammering block is arranged on the drawing shaft and above the hydraulic cylinder; a handheld handle is arranged on the hammering block; screw threads are arranged on two ends and a middle part of the drawing shaft; a drawing upper plug, a drawing lower plug and a top block are respectively arranged on positions on which the screw threads are arranged in a matching way; the three positions are main force stressing points of the extracting tool special for the orientation sub loop sleeve; the drawing lower plug is in contact with an arc face in the loop sleeve; and a bearing transition block for transiting counter-acting force of force applied to the drawing shaft by the hydraulic cylinder to an orientation sub body is arranged between the hydraulic cylinder and the orientation sub. The workload of extracting the loop sleeve is reduced, and meanwhile the problem that the sub is scrapped due to the fact that the loop sleeve cannot be extracted is solved. The extracting tool special for the orientation sub loop sleeve has the advantages of simple structure and convenience in operation.
Description
Technical field
The utility model relates to the kit that oil drilling is used the QDT inclinometer, and specifically a kind of orientation joint circulating sleeve special-purpose taking goes out instrument.
Background technology
Due to oil field large tracts of land exploitation for many years both at home and abroad, oil reservoir development steps into the middle and later periods gradually, the difficulty of oil reservoir exploitation constantly increases, in wellbore construction, directional well, the shared ratio of horizontal well increase gradually, and the use of QDT Wireless Measurement-while-drilling Technology is also more and more extensive, QDT supporting technology and the instrument important function in wellbore construction also highlights gradually, therefore, significant to raising drilling efficiency, saving drilling cost in conjunction with the characteristic study of site operation new supporting technology and instrument.The taking-up work of orientation joint circulating sleeve in the past is generally by manpower hammering mode, by force circulating sleeve is pounded out.Its shortcoming is that labour intensity is large by manpower, and potential safety hazard is many, very easily cause accessory loss and security incident, and success rate is lower, thereby brings scrapping of joint, makes QDT instrument running cost greatly improve.These drawbacks in existing orientation joint circulating sleeve removing method are that to be present in the QDT instrument in service, therefore, improve existing orientation joint circulating sleeve removing method and instrument and have very important realistic meaning.
In view of this, for the problems referred to above, propose a kind of orientation joint circulating sleeve special-purpose taking reasonable in design and that effectively improve above-mentioned disappearance and go out instrument.
Summary of the invention
The purpose of this utility model is to provide a kind of orientation joint circulating sleeve special-purpose taking to go out instrument, has reduced the amount of labour of getting circulating sleeve, has solved simultaneously the problem of scrapping joint because circulation can not be extracted out.Have advantages of simple in structurely, easy to operate, filled up the blank that the orientation joint circulating sleeve takes out instrument.
In order to reach above-mentioned purpose, the utility model adopts following technical scheme: a kind of orientation joint circulating sleeve special-purpose taking goes out instrument, comprises the drawing axle, is arranged on the hydraulic cylinder on the drawing axle; Described drawing axle lower end is passed the endoporus of the circulating sleeve of the hydrophthalmia of orientation joint and orientation joint inside successively.
On described drawing axle and hydraulic cylinder top position section is equipped with the hammering piece.
On described hammering piece, hand-held handle is installed.
Described drawing axle two ends and middle part are provided with screw thread, coordinate respectively drawing upper plug head, drawing lower end cap, jacking block are installed offering the screw thread place, and this position, three places is the main stress point that orientation joint circulating sleeve special-purpose taking goes out instrument.
Described drawing lower end cap contacts with the inner cambered surface of circulating sleeve.
Be equipped with between described hydraulic cylinder and orientation joint hydraulic cylinder is imposed on the pressure-bearing transition block that directed joint body is given in the reaction force transition of the power of drawing axle.
Compared to prior art, the utility model greatly reduces circulating sleeve and takes out workload, has solved simultaneously the problem of scrapping joint because circulation can not be extracted out.Orientation joint circulating sleeve special-purpose taking in the utility model goes out instrument, simple in structure, easy to operate, has filled up the deficiency of QDT instrument kit.
Description of drawings
Fig. 1 is the structural representation that a kind of orientation joint circulating sleeve of the utility model special-purpose taking goes out instrument.
In figure: 1, drawing axle; 2, pressure-bearing transition block; 3, hydraulic cylinder; 4, jacking block; 5, hammering piece; 6, drawing upper plug head; 7, circulating sleeve; 8, drawing lower end cap; 9, orientation joint.
The specific embodiment
Relevant detailed description of the present utility model and technology contents coordinate description of drawings as follows, yet accompanying drawing only provides the use of reference with explanation, and the utility model is limited.
According to shown in Figure 1, a kind of orientation joint circulating sleeve special-purpose taking goes out instrument, comprises hydraulic cylinder 3, drawing axle 1, pressure-bearing transition block 2, jacking block 4, hammering piece 5, drawing upper plug head 6 and drawing lower end cap 8.There is screw thread drawing axle 1 two ends and middle part, be connected with drawing upper plug head 6, drawing lower end cap 8 and jacking block 4 respectively, and to be threaded are the main stress points that orientation joint circulating sleeve special-purpose taking goes out instrument at this three place; This drawing axle 1 passes orientation joint 9 hydrophthalmias and circulating sleeve 7 endoporus; Drawing lower end cap 8 contacts with the inner cambered surface of circulating sleeve 7; Between hydraulic cylinder 3 and orientation joint 9, pressure-bearing transition block 2 is housed, pressure-bearing transition block 2 imposes on hydraulic cylinder 3 the reaction force transition of the power of drawing axle 1 and gives directed joint 9 bodies, increase hydraulic cylinder 3 pressure-bearing surfaces, avoid simultaneously hydraulic cylinder 3 to destroy orientation joint 9 box faces; On hammering piece 5, handle is housed, can so that hammering piece 5 moves up and down along drawing axle 1, makes drawing axle 1 can be applied in hammer force at work by manually-operated.
It is to convert hydraulic energy to kinetic energy that this orientation joint circulating sleeve special-purpose taking goes out instrument, follows simultaneously the hammering of hammering piece, and dual mode is accomplished circulating sleeve taking-up work by joint efforts.
The above is only preferred embodiment of the present utility model, and non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
