WIRELINE SYSTEM AND METHODS OF USING SAME

摘要

A wireline system for use during drilling operations. The wireline system has a wireline assembly and a roller assembly. Both the wireline assembly and the roller assembly are positioned within a front portion of a drill rig. Described herein, in one aspect, is a wireline system for use on a drill rig. The drill rig can comprise a drilling sytem, and the drilling system can comprise a mast, a drill string, and a drill head configured to impart rotation to the drill string within a drilling formation.

1. A wireline system for use on a drill rig comprising a mast, a drill string, and a drill head configured to impart rotation to the drill string within a drilling formation, the mast having a longitudinal axis and opposed first and second ends, the first end of the mast being configured for positioning proximate the drilling formation, the drill rig having a first transverse axis and a second transverse axis extending perpendicularly relative to the first transverse axis, wherein when the mast is positioned in a vertical position, the first and second transverse axes are substantially perpendicular to the longitudinal axis of the mast, wherein the first transverse axis divides the drill rig into a front portion and a back portion, wherein the second transverse axis extends from the front portion of the drill rig to the back portion of the drill rig, the wireline system comprising:
a wireline assembly operatively secured to the mast at a first axial location relative to the longitudinal axis of the mast, the first axial location being proximate the first end of the drill mast, wherein the wireline assembly comprises a drum configured for engagement with a drilling cable; and a roller assembly operatively secured to the mast at a second axial location relative to the longitudinal axis of the mast, the second axial location being positioned between the first axial location and the second end of the mast relative to the longitudinal axis of the mast, wherein the roller assembly is configured for engagement with the drilling cable, wherein the wireline assembly and the roller assembly are positioned within the front portion of the drill rig, and wherein at least a portion of the wireline assembly and at least a portion of the roller assembly are axially spaced from the mast relative to the second transverse axis.
