Abstract
The utility model provides a multidirectional connector. The multidirectional connector comprises an upper connector body, a circulating connector body, a connecting body and a lower connector body. The multidirectional connector is characterized in that the upper connector body, the circulating connector body, the connecting body and the lower connector body are connected with one another in sequence, internal threads are arranged on the upper connector body, the connecting body and the lower connector body are respectively provided with external threads, the outer diameter of the connecting body is larger than the outer diameter of the upper connector body and the outer diameter of the lower connector body, the circulating connecting body tapers from bottom to top, the multidirectional connector can be connected with three tubular posts at the same time, the improvement of the dredging efficiency of a drilling tool and the improvement of the milling efficiency of the drilling tool are facilitated, the accident handling speed is improved, the accident handling time is shortened, the accident losses are reduced, and the multidirectional connector can be widely applied to petroleum and natural gas drilled hole accident handling work.
Description
Technical field
The utility model relates to connector, is specifically related to multi-way connector.
Background technology
In petroleum drilling operation down-hole accident processing procedure, down-hole accident often occurs.Due to hole anomaly, pregnant well section is arranged sometimes or step is arranged, the accident treatment difficulty.Simultaneously, after drilling tool accident occurred, often the fish head was not placed in the middle, and fishing tool is difficult to enter smoothly the fish hydrophthalmia, salvages difficulty with fishing tool.And the fish head is not placed in the middle, with the easy eccentric wear of milling tool, milling speed is slow, and instrument easily damages, and makes a trip many, increases the accident treatment time, even, because well is difficult to clean in time, causes great bit freezing risk.After drilling tool accident occurred, annular space often had sand setting, after needing cover to mill, just can salvage or milling operation, had also increased the accident processing time.
The utility model content
Technical problem to be solved in the utility model is to provide multi-way connector.
In order to address the above problem, according to the technical solution of the utility model, multi-way connector comprises top connection, circulating connection, connector and lower contact; Be characterized in: top connection, circulating connection, connector and lower contact are linked in sequence, described top connection is provided with internal thread, described connector and lower contact are provided with external screw thread, and the connector external diameter is larger than top connection external diameter and lower contact external diameter, and circulating connection has up-small and down-big tapering.
The beneficial effect of multi-way connector described in the utility model is: the utility model can connect three tubing strings simultaneously, be conducive to improve drilling tool salvaging, milling efficiency, accelerate accident treatment speed, shorten the accident treatment time, reduce causality loss, can be widely used in oil, the operation of gas drilling accident treatment.
The accompanying drawing explanation
Fig. 1 is the structural representation of multi-way connector described in the utility model.
The specific embodiment
Referring to Fig. 1, multi-way connector consists of top connection 1, circulating connection 2, connector 3 and lower contact 4; The lower end of top connection 1 connects the upper end of circulating connection 2, the lower end of circulating connection 2 connects the upper end of connector 3, the lower end of connector 3 is connected with the upper end of lower contact 4, described top connection 1 is provided with internal thread, connector 3 and lower contact 4 are provided with external screw thread, connector 3 external diameters are larger than top connection 1 external diameter and lower contact 4 external diameters, and described circulating connection 2 has up-small and down-big tapering.
During concrete the use, top connection 1 and drilling rod or drill collar are threaded connection, lower contact 4 is threaded connection fishing tool, milling tool etc., can realize fish is salvaged or milling operation.And, also connector 3 can be threaded connection to other tubing strings such as milling pipe, sleeve pipe, the tubing string end can connect and mill circle, annular space is overlapped and mill, and clean annular space, then salvage immediately, is conducive to save the trip time.The tubing string end can be arranged to wall hook, and the guiding fish enters in tubing string fast, and makes the fish head placed in the middle, improves and salvages efficiency.
