Embodiment

[0027] Such as figure 1 Shown here is an embodiment of the multifunctional centralizer for workover operations of the present invention. The centralizer first includes a fixed base 1 on which a horizontal main rail 2 is installed. There are two main rails 2 which are symmetrically distributed on both sides of the base 1. A horizontal working platform 3 reciprocates on the main rail 2. The movement of the working platform 3 is realized by the following structure:

[0028] A lead screw 10 parallel to the main rail 2 and driven to rotate by a servo motor 11 is installed on the base 1, and a lead screw female buckle 12 is fixed on the lower surface of the working platform 3. The lead screw 10 Passing through the screw female buckle 12 and threadedly matching with the screw female buckle 12, when the servo motor 11 drives the screw 10 to rotate, the screw female buckle 12 can drive the working platform 3 to reciprocate linearly.

[0029] Such as figure 1 with figure 2 As shown, the wor...

Abstract

The invention discloses a multifunctional righting hand for well workover operations, which solves the above-mentioned problems existing in the prior art when performing overhaul operations. The multifunctional righting hand for well workover operation includes a base on which a horizontal main rail is installed, and a horizontal working platform is reciprocally sliding on the main rail; The auxiliary track is perpendicular to the track, and there are two sets of symmetrically arranged handrail mechanisms sliding reciprocatingly on the auxiliary track. Each set of handrail mechanisms includes two freely rotatable rollers. The central axes of the two rollers are aligned with the working platform. Parallel, the included angles between the central axes of the two rollers and the auxiliary track are 45° and 135° respectively, and the four rollers form a rectangle. The multifunctional righting hand for well workover operation has a simple structure and is easy to use, and can accurately and effectively right up a pipe string to successfully complete the workover operation.

Description

Technical field [0001] The invention relates to the technical field of equipment for workover operations, in particular to a multifunctional righting hand for workover operations. Background technique [0002] Workover operation refers to an operation of oil drilling and subsequent oil well maintenance. Maintenance and maintenance measures are taken to ensure the smooth use of oil wells. The workover project is difficult and requires high technical requirements. It is necessary to use large workover equipment and be equipped with special equipment tools such as overhaul drill pipes and overhaul turntables to carry out the work. [0003] At present, when the platform manipulator is used for overhaul operations, the column (connecting body of two or three drill pipes) in the downhole to the thread or the cooperation between a single string and the tubing lift often has the following problems: First, how The male buckle of the pipe string arriving at the wellhead is precisely matched...
