Abstract

The invention provides a coiled tubing length measuring device comprising an installing shell, a connector, a counter and a connecting shaft. The installing shell is used for installation and fixing with coiled tubing equipment. The connector is connected with the tubing output device of the coiled tubing equipment in a driving way. The counter is installed in the shell. The connecting shaft is connected with the connector and the input end of the counter. With application of the coiled tubing length measuring device, a problem of high length measurement error caused by the fact that the coiled tubing length measuring device and tubing are liable to slip in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the field of oil field technology, in particular to a coiled tubing length measuring device. Background technique [0002] Coiled tubing is a kind of equipment used in oil and gas well operations. The coiled tubing length measuring device is an important part of the coiled tubing equipment. Its main function is to measure the length of the coiled tubing running into or out of the oil well in real time during operation. . [0003] The existing coiled tubing machine length measuring device is composed of a roller, a roller assembly, a mechanical type, an electronic type, a spring, and a casing coaxially connected with the roller. When the tubing machine is in operation, the tubing wound on the drum passes through the device, so that the rollers in the device are pressed into contact with the tubing. The rollers rely on the friction between the tubing and the tubing to realize their own rotation when the tubing is lowered or lift...
