Abstract
In accordance to an aspect a connection to attach a first downhole tool to a second downhole tool includes an externally threaded member positioned about the first downhole tool and an internally threaded member disposed with the second downhole tool to threadedly mate with the externally threaded member, wherein threadedly connecting the externally threaded member with the internally threaded member interconnects the first downhole tool and the second downhole tool with a defined tensile force and a compressive force at an interface between a hard shoulder of the first downhole tool and a hard shoulder of the second downhole tool.
Claims20
A downhole tool connection assembly, the assembly comprising:
- an externally threaded member rotatably positioned about a first downhole tool;
- an internally threaded member disposed with a second downhole tool to threadedly mate with the externally threaded member;
- and
- a stop located on one of the first downhole tool and the second downhole tool to act on one of the internally threaded member and the externally threaded member when threadedly connected, whereby the threaded connection interconnects the first downhole tool and the second downhole tool with a defined tensile force and a compressive force at an interface between a first hard shoulder of the first downhole tool and a second hard shoulder of the second downhole tool.
A drilling system, comprising:
- a drill string disposed in a wellbore, the drill string having a first downhole tool connected to a second downhole tool by a connection assembly with a defined tensile force and a compressive force at an interface between a first hard shoulder of the first downhole tool and a second hard shoulder of the second downhole tool, the connection assembly comprising:
- an externally threaded member rotatably positioned about the first downhole tool;
- an internally threaded member disposed with the second downhole tool and threadedly mated with the externally threaded member;
- and
- a stop located on one of the first downhole tool and the second downhole tool to act on one of the internally threaded member and the externally threaded member when threadedly connected.
A method, comprising:
- interconnecting a first downhole tool and a second downhole tool with a defined tensile force and a compressive force at an interface between a first hard shoulder of the first downhole tool and a second hard shoulder of the second downhole tool, the interconnecting comprising:
- threading an externally threaded member rotatably positioned about the first downhole tool with an internally threaded member disposed with the second downhole tool, wherein a stop located on one of the first downhole tool and the second downhole tool to act on one of the internally threaded member and the externally threaded member when threadedly connected.
