Reaming device for oil and gas drilling

Abstract

The invention discloses a reaming device for oil and gas drilling. The device includes a second conical drill bit, first hydraulic telescopic rods, a mounting plate, a mounting shell and a base, wherein telescopic rods are mounted on both sides of the bottom of the base, limit holes are evenly distributed on the telescopic rods, the bottom of the telescopic rods is equipped with fixing pins, walking wheels are mounted at the bottom of the base among the telescopic rods, the top of the base is equipped with a mounting plate through two sets of second hydraulic telescopic rods, and the central position of the bottom of the mounting plate is equipped with the first hydraulic telescopic rods. The device is advantaged in that through the second conical drill bit, the first hydraulic telescopicrods, the mounting plate, the mounting shell and the base, the walking wheels can facilitate the staff to quickly transfer the device according to the actual situation, the hydraulic telescopic rods can be adjusted and lifted according to the working condition, cameras can facilitate the staff to observe the internal drilling situation when the device is in operation, and the device has strong practicability and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of drilling and reaming, in particular to a reaming device for oil and gas drilling. Background technique [0002] With the deepening of the understanding of the mechanism of oil and gas accumulation and the development of oil and gas fields, the problems encountered in drilling are becoming more and more complex, and the solutions to these complex problems are increasingly dependent on the development of tools and means. It is proposed and developed based on this background that the so-called reaming-while-drilling technology is a drilling technology that uses reaming-while-drilling tools and conventional drill bit procedures to expand the wellbore while fully drilling. There is a lack of drilling devices, and the operating performance is relatively simple. Although the traditional drilling reaming device has achieved the basic reaming operation, the overall structure is relatively complicated and the volum...

Problems solved by technology

[0002] With the deepening of the understanding of the mechanism of oil and gas accumulation and the development of oil and gas fields, the problems encountered in drilling are becoming more and more complex, and the solutions to these complex problems are increasingly dependent on the development of tools and means. Proposed and developed based on this background, the so-called reaming-while-drilling technology is a drilling technology that uses reaming-while-drilling tools and conventional drill bit procedures to expand the wellbore while fully drilling. There is a lack of drilling devices, and the operating performance is relatively simple. Although the traditional drilling reaming device has achieved the basic reaming operation, the overall structure is relatively complicated and the volume is large. This not only easily leads to device failure, but also has poor flexibility and disadvantages. The movement reduces the practicability of the device. At the same time, the traditional drilling and reaming technology cannot enable the staff to quickly grasp the internal situation of the drilling, resulting in the failure of the device's operating efficiency and quality to be improved.
