Description

Technical Field

[0001] The utility model belongs to the field of oil and gas drilling and completion engineering, and specifically relates to a bracket device for measuring the length of a drilling tool in cooperation with a laser rangefinder. Background Art

[0002] In the process of drilling and completion of oil and gas wells, a large number of drilling and completion tools are needed, such as drill pipes, casings, tubings, etc. Before entering the well, these drilling and completion tools need to be measured in length without exception. The traditional method is to use a steel tape measure, but there are many disadvantages in using a steel tape measure to measure length. For example, when the drilling and completion tools are long, the steel tape measure is not easy to straighten, the zero point of the steel tape measure is easy to shift during measurement, and it is difficult to measure in bad weather such as strong winds. In addition, manual readings will also produce errors due to human subjective arbitrariness. All of the above disadvantages have caused the use of steel tape measures to measure length at the drilling and completion site. The efficiency is low and the accuracy is poor, thus affecting the overall operation efficiency. Laser ranging technology is an advanced technology for measuring length with high efficiency and high precision. Applying laser ranging technology to the measurement of drilling and completion tools at the drilling and completion site of oil and gas wells can greatly improve the operation efficiency. However, most drilling and completion tools are tubular structures, and laser rangefinders cannot be directly used to measure drilling and completion tools. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] The utility model auxiliary laser rangefinder is used to measure drilling and completion tools at the drilling and completion operation site. The drilling and completion tools include oil pipes, casings and various pipe fittings, and the drilling and completion tools are mostly tubular structures.

[0030] Example 1

[0031] A bracket device system for measuring the length of a drilling and completion tool in cooperation with a laser rangefinder at a drilling and completion operation site, comprising a measuring baffle 1 and a bracket baffle 2 arranged opposite to each other; a hollow bracket baffle base 23 is arranged on the side of the bracket baffle 2 facing away from the measuring baffle 1, a horizontal arm of a T-shaped bracket base clamping plate 4 is inserted into the hollow structure of the bracket baffle base 23, a vertical arm of the bracket base clamping plate 4 is arranged parallel to the bracket baffle 2, and a bracket spring 3 is arranged between the two, and the bracket spring 3 is located below the bracket baffle base 23; a measuring window 22 is formed on the bracket baffle 2, a laser rangefinder 5 is placed on the bracket baffle base 23, and a laser emission port of the laser rangefinder 5 is located within the range of the measuring window 22.

[0032] Since the measuring window 22 is set larger, it is convenient to adapt to laser rangefinders 5 of various sizes. In order to facilitate the placement of small-sized laser rangefinders 5, the bracket baffle 2 is symmetrically provided with measuring baffles 21 on one side facing away from the measuring baffle 1. The two measuring baffles 21 are arranged at intervals, and each of them has a part covering part of the measuring window 22. The laser rangefinder is clamped between the clamping plate and the measuring baffles, and emits laser measurement signals through the gap between the measuring baffles.

[0033] In this embodiment, a fixed handle 11 is welded at the lower middle position of the side of the measuring baffle 1 facing away from the bracket baffle 2, and the handle 11 in this embodiment is T-shaped, which can facilitate the measurement baffle 1 to be taken and fit on the end face of the required measuring tool.

[0034] The laser rangefinder 5 is placed on the bracket baffle base 23, and its two ends are clamped by the measuring baffle 21 or the bracket baffle 2 and the bracket base clamping plate 4 respectively; since the bracket base clamping plate 4 can be inserted into the hollow structure of the bracket baffle 2, and the bracket baffle 2 and the bracket base clamping plate 4 are connected together through the bracket spring 3, the elastic force of the spring can clamp the laser rangefinder of any brand and size on the market.

[0035] The bracket measuring device is preferably made of aluminum alloy as a whole, which is light in weight and corrosion-resistant.

[0036] The measuring baffle 1 and the bracket baffle 3 both adopt a flat plate structure, which can be conveniently attached to the two ends of the required measuring tool.

[0037] The use of the utility model:

[0038] By placing the measuring baffle 1 at one end of the drilling and completion tool 6 and fitting it to the end face of the tool, placing the laser rangefinder 5 on the bracket baffle base 23 and clamping it between the bracket base clamping plate 4 and the measuring baffle 21, and then placing the bracket baffle 2 at the other end of the drilling and completion tool 6 and fitting it to the end face of the tool, the laser rangefinder is started. Since the interior of the drilling and completion tool is mostly a hollow area, the laser can pass through unobstructed. After the laser signal encounters the measuring baffle, the signal is reflected back to the rangefinder, thereby realizing the measurement of the tool length.

[0039] The utility model uses the bracket base on the bracket baffle as a clamping carrier of the laser rangefinder, can conveniently and quickly clamp the laser rangefinder, and uses the measuring baffle as a laser signal reflection carrier, thereby realizing the length measurement of the drilling and completion tool, reducing the operation time and improving the work efficiency.
