Drill Pipe Length Measurement Posted in: Length Measurement – Tags: Mining, Oil and Gas
When drilling down for oil and gas, the drill tower and drill are attached to a piece of pipe. As the drill pipe is being drilled lower and lower into the ground, laser rangefinders are used to monitor the distance to the platform.
One customer has used the internal module of AR2500 laser sensors to notify workers to attach the next pipe to continue to drill deeper into the ground. The sensor is mounted in a collar at the top and continually measures the distance to the platform until the process is complete. Laser sensors measure the real time length of each pipe as it is drilled into the ground. The length measurement of the pipe is used to measure the total depth the pipes are into the ground.
Similar rangefinder pipe length applications have been used for operators in drill rigs and pile drivers. The rangefinder is installed at the deck and pointed up to the rotary head drilling down. The laser is zeroed out at a “home position” and the Acuity touch panel display gives the operator the current length of the pipe as it’s fed into the ground.
This solution reduces the operator’s reliance on best guess judgement of the current depth into the ground. Our laser rangefinders are NEMA-4, IP65 or IP67 enclosures built for tough industrial environments for indoor/outdoor environments.
AS1100 Long Distance Sensor
The Acuity AS1100 Long Distance Sensor can measure up to 100 meters on natural targets and up to 150 meters away with an Acuity reflective plate with an accuracy of ± 3 mm. This rugged sensor is built for versatile environments and is often used in applications that involve measurements on hot materials.
AS2100 Accurate Distance Sensor
The AS2100 is a highly accurate laser distance sensor that is designed to work well outdoors, in bright lights, and even on difficult targets such as hot or dark surfaces. With the ability to take accurate measurements (± 1 mm) from distances up to 500 meters away, and a measurement frequency of up to 250 Hz, it is the perfect laser for a wide range of applications.
AR2700 High-Speed Long Range Sensor
Acuity Laser’s ultra-compact rangefinder model. This eye-safe rangefinder has a measurement frequency of up to 40 kHz and can measure distances to natural targets up to 70 meters away or to retroreflective targets 270 meters away. This laser is best for applications that demand high sampling rates.
