Description
Technical field：
The utility model is related to oil well logging instrument technical field, more particularly to a kind of magnetic orientation well-logging probe.
Background technology：
In order to obtain it is full and accurate effectively, accurately downhole data, oil play propose logging operation link more next
Higher requirement.It is required that log data is precisely efficient, oil reservoir position, sandstone pores and oiliness are judged for oil field subsequent development
Scientific basis is provided.In daily logging operation, school is indispensable logging technique deeply, direct relation whether deep accurate in school
The accuracy of data acquisition, the precision of school depth decides the precision of all log datas in a certain sense.It would therefore be highly desirable to it needs
A kind of logging operation simplicity, depth value is wanted to control accurate, the school depth method of data-interface good compatibility.CCL logging instruments meet the tendency of and
It is raw, since it is using the characteristics of easy, error is low, favorable repeatability, it is widely used in the well logging school depth field in multiple oil fields.
But the magnetic orientation probe of current country CCL logging instruments can only survey 7 " with setting of casing.
Utility model content：
The technical problem to be solved by the present invention is to provide a kind of magnetic orientation well-logging probes, and the arrangement achieves structures to set
Meter is reasonable, can be used in 9, and " 5/8 big borehole size, line construction is simple, and size is consistent with original CCL magnetic orientations probe, surveys
High sensitivity is measured, accuracy rate is high.7 can only be tested " with setting of casing, measurement standard by overcoming the magnetic orientation probe of existing CCL logging instruments
The low deficiency of true rate.
Technical solution adopted in the utility model is：A kind of magnetic orientation well-logging probe, including pressure-resistant no magnetic shell；It is pressure-resistant
No magnetic enclosure is equipped with magnet steel I and magnet steel II, and against putting, magnet steel I and magnet steel II pass through line for magnet steel I and II same polarity of magnet steel
Ring framework is connected, and coil is arranged on coil rack, I outside connection adjustment part I of magnet steel, I outside of adjustment part sets axial damping
Device, II outside connection adjustment part II of magnet steel, II outside of adjustment part sets radial shock absorber, dismounting supporting is terminated outside radial shock absorber
Body, pressure-resistant no magnetic shell both ends are connected respectively by jointing with carrying silk.
Magnet steel I and magnet steel II are fastened on by no magnetic screw on coil rack.
The beneficial effects of the utility model are：The utility model realizes reasonable in design, " the 5/8 big well that can be used in 9
Eye size, line construction is simple, and size is consistent with original CCL magnetic orientations probe, and measurement sensitivity is high, and accuracy rate is high.
Description of the drawings：
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structure diagram of the utility model.
Specific embodiment：
As shown in Figure 1, a kind of magnetic orientation well-logging probe, including pressure-resistant no magnetic shell 3；Pressure-resistant no magnetic shell 3 is internally provided with
Against putting, magnet steel I 5 and magnet steel II 8 pass through 6 phase of coil rack for magnet steel I 5 and magnet steel II 8, magnet steel I 5 and II 8 same polarity of magnet steel
Even, coil 7 is arranged on coil rack 6, the magnetic direction that two blocks of magnet steel are formed is on the contrary, magnet steel, coil rack 6 form and stablize magnetic
.I 5 outside connection adjustment part I 2 of magnet steel, I 2 outside of adjustment part set axial vibration damper 4, II 8 outside connection adjustment part II of magnet steel
11, II 11 outside of adjustment part sets radial shock absorber 9, and dismounting supporting mass 10 is terminated outside radial shock absorber 9, is easily installed dismounting.
Pressure-resistant no 3 both ends of magnetic shell are connected respectively by jointing with carrying silk 1.
Magnet steel I 5 and magnet steel II 8 are fastened on by no magnetic screw on coil rack 6.
Magnetic orientation well-logging probe is integrally connected under halter, and when going into the well in the case where not interfering with, magnetic field intensity is constant,
In coil 7 by magnetic flux it is constant, will not generate at this time induced electromotive force output.But by being covered during casing joint position
Thickness of pipe wall changes, and changes the distribution in magnetic field, and magnetic flux changes in coil 7, generates induced electromotive force.In coil 7
It contacts collar location and an equidirectional small spike, one negative direction at centre position can all occur when leaving collar location
Big spike because Distribution of Magnetic Field variation is maximum at centre position.The both ends of coil 7 export induced electromotive force to acquisition electricity
Lu Zhong, Acquisition Circuit is amplified signal, filters, shaping, the processing such as compares, and is handled by process circuit and uploads to meter
It is shown in calculation machine.Equidirectional 2 small spikes and 1 negative direction up and down can all be occurred in casing collar location by finding out from curve
Big spike.
It is understood that above with respect to the specific descriptions of the utility model, it is merely to illustrate the utility model and is not
The described technical solution of the utility model embodiment is limited to, it will be understood by those of ordinary skill in the art that, it still can be with
It modifies to the utility model or equivalent substitution, to reach identical technique effect；As long as meet using needs, all in this reality
Within new protection domain.
