specific Embodiment approach

[0022] Such as Figures 1 to 3 As shown, the cable hanger for wells includes a main body 1, and a fixing assembly is installed in the inner cavity of the main body 1. The fixing assembly includes a slip seat 2 and a slip 3 installed on the slip seat 2 , and a fastening push rod 4 for pushing the fixing assembly to move axially is installed in the inner cavity of the main body 1 .

[0023] One side of the slip 3 is open so that the cross-section is C-shaped, and a plurality of slits 12 are provided in the upper axial direction of the slip 3 .

[0024] The cable passes through the fastening push rod 4 and the slips 3, and is sent into the inner cavity of the hanger main body 1. The fastening push rod 4 pushes the fixed assembly, one of the slips 3 and the slip seat 2 is limited by the inner cavity, and the other is pushed by the fastening push rod 4, so that the slips 3 and the slip seat 2 move toward each other. The wedge surface set on the outer wall of the slip 3 and the we...

Abstract

The invention discloses a mine cable hanger which comprises a main body; fixing components are mounted in an inner cavity of the main body, and comprise slip bowls and slip elements mounted on the slip bowls; a fastening push rod for pushing the fixing components to move axially is mounted in the inner cavity of the main body; the cross sections of the slip elements are C-shaped; and a plurality of gaps are axially formed in the slip elements. According to the mine cable hanger, the slip elements or the slip bowls are pushed to move through the fastening push rod, the slip elements generate radial deformation through the mutually contacted wedge surfaces of the slip elements and the slip bowls, cables in the slip elements are surrounded and locked, and the hanging fixing of the cables is realized. The slip elements are C-shaped and formed openings increase the deformation amounts of the slip elements, and the gaps improving the deformation are additionally formed in the slip elements, so that the deformation degree of the slip elements is further raised, the slip elements can hold the cables to a greater extend, a locking force is increased, and the fastness of the hanging fixing is improved.

Description

technical field [0001] The invention relates to the technical field of oil and gas, in particular to a hanger for ground cables used in well logging and sidetracking operations in oil and gas fields. Background technique [0002] As the industry's requirements for oil and gas field operations are getting higher and higher, and the degree of operation precision is getting higher and higher, the application of wireline logging and sidetracking operations for oil and gas wells is becoming more and more frequent. In wireline logging and sidetracking operations, one end of the cable must be firmly fixed on the reel to prevent it from falling into the wellhead during the operation and causing accidents. In addition, the reliability of sealing and connection during cable signal transmission requires a very high degree of guarantee. Therefore, a cable hanger with good connection, suspension performance and sealing performance will greatly help the wireline logging operation. [00...
