Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] A system for automatically measuring the length of drilling tools, the schematic diagram of its on-site installation is as follows figure 1 As shown, the drilling tool transfer device at the center of the base 2 can slide back and forth along the base 2 . The upper surface of the drilling tool transfer device has a V-shaped groove 3, and the drilling tool 1 will not roll out of the groove when it is located in the V-shaped groove 3. The drilling tool transfer device is equipped with a small trolley 4, which can slide back and forth along the V-shaped groove 3. The front end of the small trolley 4 is fixed with a reflection measurement plate 5, and the rear end of the base 2 is equipped with a laser ranging head 6. The head 6 emits a laser beam directly to the reflective measurement plate 5, and a photoelectric sensor 7 is fixed on the outside of...

Abstract

The invention relates to a system for automatically measuring the length of a drilling tool, which includes a base and a drilling tool transfer device on the base. The upper surface of the drilling tool transfer device has a V-shaped groove for placing the drilling tool. Small trolley, the front end of the small trolley is fixed with a reflective measurement plate, and the rear end of the base is equipped with a laser ranging head for emitting laser beams forward. There is a photoelectric sensor, the light beam of the photoelectric sensor is located above the V-shaped groove and perpendicular to the V-shaped groove, the laser distance measuring head and the photoelectric sensor are connected to a controller, and the controller controls the connection of the small pulley. The invention also provides a method for automatically measuring the length of the drilling tool. The solution solves the problem of low efficiency in measuring the length of the drilling tool by means of the prior art.

Description

technical field [0001] The invention relates to oil exploration equipment technology, in particular to a system and method for automatically measuring the length of a drilling tool. Background technique [0002] In the process of oil drilling, there are a large number of drilling tools such as drill pipes, drill boats, and casings that need to measure their length. The actual length of the drilling tool can directly reflect the drilling depth of the drilling rig, and is an important indicator in the drilling process. Automatically and accurately measuring the length of the drilling tool without omission has become an important task in drilling operations. In traditional drilling operations, the staff use a tape measure to measure the length of the drilling tool and record it manually. However, in a conventional drilling site, the total number of drilling tools to be measured is as many as one hundred. The measurement workload is large, the efficiency is low, the accuracy is...
