Description
Technical field
The utility model relates to a kind of emitter, relates in particular to one and can repair super far-end high power strong magnetic emitter.
Background technology
In the special well work progresss such as current China coal bed gas, salt well, SAGD well and fireflood well, connection technology application is ripe gradually, but the realization of this activities necessarily be unable to do without strong this instrument of magnetic emitter, strong magnetic emitter connects on drilling tool screw drive head, in normal drilling process, strong magnetic emitter, under High Rotation Speed state, produces alternating electromagnetic field, the reception sources being lowered at straight well, receiving system is according to the direction of the electromagnetic field of emission source transmitting, and guiding two wells are realized wearing.At present domestic strong magnetic emitter application is also more extensive, but also has a lot of defects, and we only study one of them: unrepairable.In wellbore construction process, all can there is the phenomenon of pin end wearing and tearing more serious (box end relatively) in tool joint, and this is the matter of common sense of drilling well industry, and strong magnetic emitter is no exception.
To the technology of wearing be horizontal well (positive drilling well) to wearing straight well (drilled well), technique is mainly that the magnetic signal receiving by inserting tube guides, wherein signal source is the magnetic short section near drill bit.The coverage of the signal of magnetic short section generation is both at home and abroad 50 to 60 meters at present.This distance, when wearing operation, if need the well section of adjusting to exceed 60 meters, there will be the accident of well filling.Also having in wellbore construction process, all can there is the more phenomenon of serious (comparing box end) of pin end wearing and tearing in tool joint, and this is the matter of common sense of drilling well industry, and strong magnetic emitter is no exception.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem one can repair super far-end high power strong magnetic emitter.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises magnet steel, multiple the first magnet steel chamber and multiple the second magnet steel chamber, the end in described the first magnet steel chamber is connected with described magnet steel, the front end in described the second magnet steel chamber is connected with described magnet steel, and described the first magnet steel chamber and described the second interval, magnet steel chamber arrange.
Further, described magnet steel is hollow circuit cylinder body structure, for nonmagnetic substance is made.
Further, the cross section in described the first magnet steel chamber and described the second magnet steel chamber is trapezoidal.
Further, described magnet steel comprises the first little magnet steel, the second little magnet steel and the 3rd little magnet steel, and described the first little magnet steel, described the second little magnet steel and described the 3rd little magnet steel are connected successively.
The beneficial effects of the utility model are:
The application that the utility model can be repaired super far-end high power strong magnetic emitter can be put forward the utilization rate of high-strength magnetic emitter greatly, reduce wellbore construction cost, for wellbore construction quality provides guarantee, for the lower step construction of oil gas engineering provides strong support; The advantage that the utlity model has simple in structure, stable performance and grow application life.
Brief description of the drawings
Fig. 1 is a kind of structural representation of repairing super far-end high power strong magnetic emitter described in the utility model.
Fig. 2 is the structural representation of magnet steel described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2: the utility model comprises magnet steel 1, multiple the first magnet steel chamber 2 and multiple the second magnet steel chamber 3, the end in the first magnet steel chamber 2 is connected with magnet steel 1, the front end in the second magnet steel chamber 3 is connected with magnet steel 1, the first magnet steel chamber 2 and 3 intervals, the second magnet steel chamber arrange, magnet steel 1 is hollow circuit cylinder body structure, for nonmagnetic substance is made, the cross section in the first magnet steel chamber 2 and the second magnet steel chamber 3 is trapezoidal, magnet steel 1 comprises that the first little magnet steel 5, the second little magnet steel 6 and the little magnet steel 5 of the 3rd little magnet steel 7, the first, the second little magnet steel 6 are connected successively with the 3rd little magnet steel 7.
Operating principle of the present utility model is as follows:
As shown in Figure 1, the cylinder that magnet steel 1 is hollow, material is non-magnetic; Pin thread 4 for being connected of emitter.Originally the length of magnet steel 1 is 30.20mm, if pin thread 4 occurs that after the problems such as wearing and tearing, this emitter is scrapped.And we repair, be mainly because we for reserving after wearing and tearing appears in pin thread 4 the longer button distance of repairing, reach recoverability with this.
We,, through test of many times checking, are finally defined as 83.82mm, and this value is unsuitable large or little, and reason is as follows:
(1), to bear moment of torsion according to strong magnetic emitter pin thread 4 maximums be 43.4kN.m for we, experimental data is as follows:
(2), determine the length of magnet steel 1 according to pin thread 4 form of threads.If the length of magnet steel 1 is less than 83.82mm, it is repaiied button distance and can reduce, and can not meet so the overhaul button number of strong magnetic emitter completely.
As shown in Figure 2, the magnet steel 1 that magnet steel 1 is made up of the little magnet steel of 3 joint, current domestic magnet steel 1 length is generally no more than 200mm, and therefore we are divided into three joints by original magnet steel 1 length and do, and have so not only reduced magnet steel processing cost, have also improved the stability of magnet steel.
After we improve the performance parameter of magnet steel 1 etc., the magnetic signal that its circumgyration incision earth's magnetic field produces will be than original being eager to excel a lot, corresponding transmission range also can be far a lot, originally in the time of 50-60 rice, just can receive signal, use now can be repaired after super far-end high power strong magnetic emitter, just signal can be received at 90-95 rice, great like this raising wearing success rate, it is low unlike original in safety, better than original in practicality, reduce accident risk, reduce construction cost, for the lower step construction of oil gas engineering provides strong support.
Those skilled in the art do not depart from essence of the present utility model and spirit, can there is various deformation scheme to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalent structure that all utilization the utility model manuals and accompanying drawing content are done changes, within being all contained in interest field of the present utility model.
