Abstract
The utility model discloses a wireless centering fishing head while drilling, which comprises a spindle. A middle part of the spindle is sheathed with a centering device; the rear end of the spindle is equipped with ten-core connectors; a union is arranged on the spindle between each of the ten-core connectors and the centering device, wherein an external thread is arranged on the peripheral surface of the union; a baffle ring is arranged on the spindle at the rear end of the union; seal rings are arranged on the spindle in front of the centering device; the front end of the spindle is provided with a fishing body; and a traverse pin is arranged on the fishing body. The wireless centering fishing head while drilling has simple structure, therefore, a wireless clinometer while drilling can become more concise. Compared with the past device that a centering device and the fishing head are installed separately, the wireless centering fishing head while drilling can save the material (the union, five O-shaped seal rings, two ten-core connectors, a connecting pipe and an oriented seat cover) and reduce the cost; simultaneously, the wireless centering fishing head while drilling can prevent the past locking phenomenon as the centering device and the salvaging head are separated when in use and can also prevent the phenomenon of the contact without conduction or the short circuit of the ten-core connectors.
Description
Technical field
The utility model relates to the drilling technology field, especially relates to the wireless drilling inclinometers device.
Background technology
Wireless drilling inclinometers is made up of ground installation and device for subsurface measuring two parts.Ground installation comprises: pressure sensor, driller's display instrument, digital treating meter, PC and relevant cable etc.Device for subsurface measuring mainly contains by fishing head, centralizer, measurement inserting tube, battery tube, impulse generator to be formed.Wherein the connection between impulse generator, measurement inserting tube, the battery tube is finished by centralizer.Centralizer with wireless drilling downhole instrument tandem arrangement in the drilling tool center, to guarantee the accurate and effective of survey data; Fishing head then plays the effect of switch, salvaging in the upper end of wireless drilling inclinometers.Now the centralizer that uses comprises as shown in Figure 2 as lower member: union 21, ten core connectors 22, set upright gum cover 23, O RunddichtringO 24, centralizer main shaft 25, baffle ring 26, jump ring 27.The fishing head that uses comprises as shown in Figure 1 as lower member now: fishing head body 11, guiding cover for seat 12, tube connector 13, lateral pin 14, O RunddichtringO 15.Not with the product of fishing head and the design of centralizer one, the phenomenon that existing fishing head and centralizer may occur locking in use influences normally and uses in the market.
The utility model content
The purpose of this utility model is to provide a kind of wireless drilling to set upright fishing head.
For achieving the above object, wireless drilling of the present utility model is set upright fishing head and is comprised main shaft, the main shaft middle part is arranged with erection device, rear-end of spindle is provided with ten core connectors, main shaft between ten core connectors and the erection device is provided with union, the union outer peripheral face is provided with external screw thread, and the main shaft of union rear end is provided with baffle ring; Main shaft before the erection device is provided with sealing ring, and front-end of spindle is provided with the salvaging body, salvages body and is provided with lateral pin.
Described salvaging body upper end is a fillet structure.
Described erection device comprises that fixed cover is located at the beryllium-bronze cover at main shaft middle part, and outer being arranged with of beryllium-bronze cover set upright gum cover.
The utlity model has following advantage:
1. the utility model is simple in structure, makes wireless drilling inclinometers more succinct.The utility model is arranged with the fishing head branch with centralizer in the past and compares, and has saved material (union, five O RunddichtringOs, two ten core connectors, a tube connector and a guiding cover for seat), has reduced cost; The utility model has been avoided separating the locking phenomenon that centralizer and fishing head occur in use in the past simultaneously, has also avoided ten core connectors to contact the phenomenon of not conducting or short circuit.
2. salvaging body upper end is a fillet structure, salvages easily.
3. set upright gum cover and can play the effect that maintenance is set upright, the setting of beryllium-bronze cover is convenient to set upright the installation and the replacing of gum cover.
Description of drawings
Fig. 1 is the structural representation of existing fishing head;
Fig. 2 is the structural representation of existing centralizer;
Fig. 3 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 3, wireless drilling of the present utility model is set upright fishing head and is comprised main shaft 8, main shaft 8 middle parts are arranged with erection device, main shaft 8 rear ends are provided with 90 degree directions, four pins, six holes, ten core connectors 7, main shaft 8 between ten core connectors 7 and the erection device is provided with union 4, union 4 outer peripheral faces are provided with external screw thread, and the main shaft 8 of union 4 rear ends is provided with baffle ring 6; Main shaft 8 before the erection device is provided with O RunddichtringO 5, and main shaft 8 front ends are provided with salvages body 2, salvages body 2 and is provided with lateral pin 1, and lateral pin 1 is used to pick instrument.Described erection device comprises that fixed cover is located at the beryllium-bronze cover 9 at main shaft 8 middle parts, and beryllium-bronze cover 9 outer being arranged with are set upright gum cover 3.Wherein, described salvaging body 2 upper ends are fillet structure; Described main shaft 8 can be that one-body molded manufacturing forms with described salvaging body 2, also can be to be fixed together after the split manufacturing; The switch of ten core connectors 7 is contained in the lower end endoporus (this endoporus is identical with the lower end endoporus of existing salvaging body 2, and figure does not show) of salvaging body 2.
During use, union 4 is connected with the instrument string internal thread of wireless drilling inclinometers by its external screw thread; Ten core connectors in ten core connectors 7 and the wireless drilling inclinometers connect, thereby play the effect of switch; Set upright gum cover 3 and play the effect that maintenance is set upright, lateral pin 1 is used for picking instrument.
