Description
Technical Field
The utility model relates to an oil field is directional to be passed through technical field, concretely relates to big gear wheel fisher.
Background
The directional crossing technology is widely applied to river crossing operation, because of stratum uncertainty, quality problems of tools such as a drill column, a roller bit and the like and large field construction difficulty, the roller bit is easy to fall off in the operation process, and the directional crossing well cavity is large, so that the roller bit used is much larger than that of the conventional petroleum drilling operation; meanwhile, the directional operation is mostly concentrated on a horizontal well section and a nearly horizontal directional section, so the salvaging of the falling of the cone is always a big problem which troubles the directional crossing, and the salvaging difficulty is large; the fishing tools commonly used in oil drilling also cannot fish the large diameter roller cone in through fishing. The common method is to grind the roller cone by using a large-diameter grinding shoe, and the roller cone can move and is difficult to grind cleanly, so that the large-diameter roller cone is difficult to salvage, and the penetration cost is increased.
SUMMERY OF THE UTILITY MODEL
For overcoming prior art's defect, the utility model provides a bull gear fisher sets up steel wire 3 in the annular space 5 through forming at sleeve 4, male joint 7, connecting tube body 2, and the bull gear that drops slides in annular space 5 and is blocked by steel wire 3 to be proposed, realize the success of bull gear and salvage.
The utility model adopts the technical proposal that: the utility model provides a bull gear fisher includes connecting tube body 2, connecting tube body 2 respectively with female joint 1, male joint 7 fixed connection, female joint 1 tip is equipped with the screw thread, male joint 7 and sleeve 4 fixed connection are equipped with runner 6 at male joint 7 lateral wall, 6 intercommunication female joint 1 of runner 6, the hole that connecting tube body 2, male joint 7 formed and the annular space 5 that sleeve 4, male joint 7, connecting tube body 2 formed be close to female joint 1 end in the annular space 5 and be equipped with steel wire 3, 3 one end of steel wire and sleeve 4 lateral wall fixed connection.
The above technical solution can be further optimized as follows:
the steel wire 3 is radially evenly distributed along the sleeve 4, and is far away from the male joint 7 with the fixed point of sleeve 4, the free end of the steel wire 3 is close to the male joint 7.
The steel wires 3 are arranged in two layers and are distributed along the sleeve 4 in an axially staggered manner.
The flow channels 6 are symmetrically arranged.
The utility model provides a bull gear fisher through set up steel wire 3 in the annular space 5 that forms at sleeve 4, male joint 7, connecting tube body 2, the bull gear that drops slides in annular space 5 and is blocked by steel wire 3 to be proposed, realize the success of bull gear and salvage.
Drawings
FIG. 1 is a cross-sectional view of a large cone overshot;
in the figure: 1-female joint, 2-connecting pipe body, 3-steel wire, 4-sleeve, 5-annular space, 6-flow channel and 7-male joint.
Detailed Description
Referring to fig. 1, the large cone fisher comprises a connecting pipe body 2, the connecting pipe body 2 is respectively fixedly connected with a female joint 1 and a male joint 7, the end of the female joint 1 is provided with a thread, the male joint 7 is fixedly connected with a sleeve 4, the side wall of the male joint 7 is provided with a flow passage 6, the flow passage 6 is communicated with an inner hole formed by the female joint 1, the connecting pipe body 2 and the male joint 7 and an annular space 5 formed by the sleeve 4, the male joint 7 and the connecting pipe body 2, a steel wire 3 is arranged in the annular space 5 near the end of the female joint 1, one end of the steel wire 3 is fixedly connected with the side wall of the sleeve 4, when large cone fisher is carried out, the female joint 1 and the male joint 7 of the large cone fisher are connected with a fishing drilling tool according to a specified torque, the fishing drilling tool advances in a well, at the moment, the female joint 1 and the male joint of the large cone fisher, because the steel wire 3 is arranged in the annular space 5, the large-size cone can not fall out of the annular space 5 even when the horizontal section of the crossing well advances, so that the large-cone fisher is lifted out from an outlet of the crossing well, and the fishing of the large cone is successfully realized.
In the preferred embodiment, the steel wires 3 are uniformly distributed along the radial direction of the sleeve 4, the fixing point of the steel wires 3 with the sleeve 4 is far away from the male connector 7, and the free end of the steel wires 3 is close to the male connector 7, so that the large cone can more easily enter the annular space 5.
The steel wires 3 are arranged in two layers and distributed in a staggered mode along the axial direction of the sleeve 4, and the effect of preventing the large cone from falling out is better.
The flow passages 6 are symmetrically arranged, so that liquid and gas entering the annular space 5 are smoothly discharged, and the large gear is favorably salvaged.
