Embodiment Construction

[0054] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

[0055] Such as figure 1 As shown, the drilling tool connection operation tool of the embodiment of the present invention includes: a rotating lifting sub-joint 100, and the rotating lifting sub-joint 100 includes:

[0056] Hollow mandrel 1, mandrel 1 is a hollow shaft body, the inner hole can pass drilling fluid, two ends are respectively processed with threads, the upper end thread is matched with the compression nut 7, and the lower end thread is matched with the drilling tool for the corresponding operation (such as a drill collar) connected;

[0057] An axial bearing 5 is sleeved on the top end of the mandrel 1, so that the mandrel 1 can rotate relative to the bearing sleeve 4 and can bear axial load;

[0058] Bearing sleeve 4, the inner wall of the bearing slee...

Abstract

The invention provides a drilling tool connecting operation technology method and tool. The drilling tool connecting operation tool comprises a rotating lifting sub. The rotating lifting sub comprises a hollow mandrel (1), an axial bearing (5) which is arranged at the top end of the hollow mandrel (1) in a sleeving mode, a bearing sleeve (4) and a pressing device, wherein the inner wall of the bearing sleeve (4) is arranged outside the axial bearing (5) in a sleeving mode, the surface of the outer side of the bearing sleeve (4) is provided with a circular bead connected with the hollow mandrel (1), and the circular bead is provided with a conical surface and contracts toward the axis of the hollow mandrel (1) from up to down; the pressing device is located on the axial bearing (5), between the hollow mandrel (1) and the bearing sleeve (4). The drilling tool connecting operation technology method uses the rotating lifting sub. According to the drilling tool connecting operation technology method and tool, working intensity is reduced, working efficiency is improved, and the occurrence of personal injury and complexities can be effectively reduced or avoided.

Description

technical field [0001] The invention relates to the field of drilling, is specifically applied to the field of oil and gas drilling technology, and is especially suitable for the connection and disassembly of drilling tools such as drill collars, drilling instruments, screw drilling tools, jars, shock absorbers, etc., that is, a drilling tool Working methods and tools. Background technique [0002] At present, in the oil and gas industry, drilling is the process of opening the channel from the ground to the oil and gas reservoir, and plays a very important role in the process of oil and gas resource exploration and development. During the drilling process, it is necessary to connect a single drill pipe with other drilling tools and instruments, and lengthen as the drilling progresses. The current methods and problems of connecting drilling tools (such as drill collars) on site are as follows: [0003] 1. The method of connecting drilling tools (drill collars) for convention...
