Abstract
The invention discloses a cable quick connector capturing short section which is characterized by comprising an upper connector, a reset spring, a split conical block and a lower connector, wherein the lower end of the upper connector is provided with the reset spring, the upper end of the lower connector is provided with the split conical block, the lower end of the upper connector and the upper end of the lower connector are connected into a whole through threads, and the split conical block is tightly pressed by the reset spring. The invention has novel structure, can be used under the conditions of high temperature and high pressure, and is safe and reliable; under normal conditions, the transmission of tension pressure and torque and the transmission of current and electric signals can be realized; if the cable quick connector falls off or breaks, the cable quick connector can be caught (clamped), and the cable below the cable quick connector is prevented from falling to the bottom of the well through the inner hole of the test pipe column, so that complex accidents are avoided.
Description
Technical field
The present invention relates to petroleum works field, relate in particular to a kind of Quick cable connector capture short segment being connected on test string.
Background technology
In logging operation, come off or fracture accident as there is fast cable joint, cause fast cable joint and following cable to fall into test string, cause complex accident.
Existing Quick cable connector capture device is simple " C " type side opening disk, and the defect that the Quick cable connector capture device of this structure exists is easy slippage, installs complicated.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind ofly can prevent that the cable below fast cable joint is shed to the Quick cable connector capture short segment in shaft bottom.
For achieving the above object, a kind of Quick cable connector capture short segment of the present invention, comprise top connection, back-moving spring, split cone piece and lower contact, wherein, the lower end of described top connection is provided with back-moving spring, the upper end of described lower contact is provided with splits cone piece, and the lower end of described top connection is threaded and is integrated with the upper end of lower contact, and back-moving spring compression is split cone piece.
Preferably, described top connection lower end is external screw thread, and the upper end of described lower contact is internal thread.
Preferably, described in split cone piece be two corresponding conelet pieces, this cone piece is along lower contact inwall slant setting.
Beneficial effect of the present invention is:
Novel structure of the present invention can use under high-temperature and high-pressure conditions, safe and reliable; Under normal circumstances, can realize the transmission of the transmission of pressure, moment of torsion and electric current, the signal of telecommunication; As occurred, fast cable joint comes off or when fracture accident, can catch (blocking) fast cable joint, avoids the cable below fast cable joint to fall within shaft bottom by test string endoporus, causes complex accident.
Brief description of the drawings
Fig. 1 is the structure sectional view of Quick cable connector capture short segment described in the embodiment of the present invention;
Fig. 2 is the structural representation of part under logging cable.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described.
As shown in Figure 1, a kind of Quick cable connector capture short segment described in the embodiment of the present invention, comprise top connection 1, back-moving spring 2, split cone piece 3 and lower contact 4, wherein, the lower end of described top connection 1 is provided with back-moving spring 2, the upper end of described lower contact 4 is provided with splits cone piece 3, and the lower end of described top connection 1 is threaded and is integrated with the upper end of lower contact 4, and back-moving spring 2 compressions are split cone piece 3.
As the further embodiment of the present invention, described top connection lower end is external screw thread, and the upper end of described lower contact is internal thread.Described split cone piece be two corresponding conelet pieces, this cone piece is along lower contact inwall slant setting.
As implementation process of the present invention, described logging cable is made up of upper cable 5, fast cable joint 6, stube cable 7 and torpedo 8.First, catch pipe nipple and be fixed on the top of test string, then upwards promote to split cone piece 3, compression reseting spring 2 with establishing the power of working as, split that cone piece 3 is upwards opened, latus rectum becomes large, can pass through torpedo 8 and stube cable 7; As occurred, upper cable 5, fast cable joint 6 come off or when fracture accident, back-moving spring 2 is split cone piece 3 to lower compression, split that cone piece 3 moves down, latus rectum diminishes, can pass through stube cable 7, cannot and can catch (blocking) fast cable joint 6 by fast cable joint 6, avoid the stube cable 7 of fast cable joint below 6 to fall within shaft bottom by test string endoporus, cause complex accident.
Novel structure of the present invention can use under high-temperature and high-pressure conditions, safe and reliable; Under normal circumstances, can realize the transmission of the transmission of pressure, moment of torsion and electric current, the signal of telecommunication; As occurred, fast cable joint comes off or when fracture accident, can catch (blocking) fast cable joint, avoids the cable below fast cable joint to fall within shaft bottom by test string endoporus, causes complex accident.
Above; be only preferred embodiment of the present invention, but protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
