The invention provides an oil field pipe rod ultrasonic length measuring system. The system is characterized in that the measuring system comprises a main control machine, a head auxiliary machine anda tail auxiliary machine. The head auxiliary machine and the tail auxiliary machine are connected with the main control machine through a cable respectively. The head auxiliary machine and the tail auxiliary machine are arranged on both ends of a conveying device with spacing. When measuring is carried out, a pipe rod is lifted to a measuring position by a hook. The ultrasonic distance measuringsensor of the head auxiliary machine detects the distance between the head auxiliary machine and the head of the pipe rod. The ultrasonic distance measuring sensor of the tail auxiliary machine measures the distance between the tail auxiliary machine and the tail of the pipe rod. The laser distance measuring sensor of the tail auxiliary machine measures the distance between the head auxiliary machine and the tail auxiliary machine. The measured data are transmitted to the main control machine through a serial port by the head auxiliary machine and the tail auxiliary machine respectively, andthe effective length of the pipe rod is calculated by the main control machine. The system provided by invention has the advantage of accurate and simple measurement, can realize accurate measurementeven if black sealing grease or crude oil is attached to the surface of the pipe rod, and realizes automatic transportation through the conveying device and a workover rig.
Description
technical field [0001] The invention relates to a measuring system, in particular to an ultrasonic length measuring system of an oil field pipe rod. Background technique [0002] In the process of oilfield exploration and development, the measurement requirements for various pipes and rods are very strict, which is related to the accuracy of the depth of the pipes and rods lowered into the well. Depth errors may lead to serious geological and engineering consequences such as oil well scrapping and downhole accidents. . [0003] At present, when measuring pipes and poles, steel tapes or tapes are mainly used, and four people, including the recorder, the main measurer, the deputy measurer, and the ground worker, work together. This method of operation has the following disadvantages: 1. Measurement accuracy error : There will be human error or error in the measurement tools (tape or tape measure), measurement methods, and recording methods. 2. Low efficiency: low personnel e...
