Abstract

The invention relates to the field of oilfield development, and relates to an automatic oil pipe length measuring device and method for oil pipe dismounting. The device comprises a pipe rod conveyor body at least, and can also comprises a proximity switch, a pressure regulating valve, a displacement sensor and a control system; the proximity switch is detachably connected to a front baffle of thepipe rod conveyor body, and is located in the pipe rod side of the pipe rod conveyor body; the pressure regulating valve is connected with a hydraulic system of the pipe and rod conveyor body; the displacement sensor is arranged on the pipe and rod conveyor body and located under a rear baffle of the pipe rod conveyor body; and the control system is electrically connected with the proximity switch, the pressure regulating valve, the displacement sensor and the pipe rod conveyor body. Due to the adoption of the displacement sensor, the difficulty in manual measurement is effectively overcome, the dismounting length of the oil pipe is automatically measured, the accuracy and the efficiency are high, the labor intensity of workers is reduced, the hidden quality trouble of construction is effectively eliminated, and the success rate of construction is increased.

Description

technical field [0001] The invention relates to the field of oil field development, in particular to a device and method for automatically measuring the length of oil pipes when lifting and lowering oil pipes. Background technique [0002] At present, the operation of pulling up and running the pipe string is a very frequent and important part of the downhole trial repair operation. The degree of automation is low, the labor intensity of the first and second wellhead posts is high, the operating environment is poor, and the safety risks faced are also great. It is necessary to use mechanization and automation to free personnel from heavy physical labor, reduce the number of wellhead operators, reduce safety risks, and improve the company's production and operating efficiency. [0003] The traditional tripping operation mode has many on-site operators, high labor intensity, and low degree of automation. At the same time, there are safety and environmental hazards such as mech...
