Background technique

In the petroleum industry, it is often necessary to carry out workover operations. Oil workover operations are to take out the oil pipes and sucker rods, and then lower the oil pipes and sucker rods into the oil well again after maintenance or replacement. The lowered tubing and sucker rod need to reach an accurate position in the well for oil recovery operations. Therefore, it is necessary to clearly measure the length of the tubing and sucker rod before going into the well. At the same time, since the length of each oil pipe and sucker rod is different, each oil pipe and sucker rod must be measured. Most of the existing measurement methods are manual measurement. Two surveyors use a meter ruler or a tape measure to measure and record. Sometimes an oil well with a depth of several kilometers needs hundreds of oil pipes and sucker rods. Measure such a large number of oil pipes and sucker rods , time-consuming and labor-intensive, and prone to measurement errors. In order to solve this problem, an automatic measuring device has appeared. The device has a motion unit, an information processing unit, etc., and realizes accurate measurement. However, this device is an independent device, which is separated from the catwalk for moving the oil pipe and sucker rod. During use, the oil pipe and sucker rod need to be transported from the storage area to the measuring device for measurement, and then transported from the measuring device On the catwalk, the number of times of transportation increases, and the weight of the tubing is very heavy, and the actual workload does not decrease but increases.

The patent (202011048977.2) authorized by the invention team proposes a method of measuring the length of the pipe rod in the catwalk: the pipe pulling mechanism turns the sucker rod into the claw of the catwalk, and the hydraulic cylinder for measuring the length of the sucker rod pushes the sucker rod close to the starting position The positioning block is based on the initial size minus the moving distance of the displacement sensor to obtain the actual length of the sucker rod. But there is no mention of how the starting position positioning block cooperates with the catwalk action to achieve length measurement.

The patent (202010998186.X) authorized by the invention team proposes a measurement and positioning device, which directly drives the positioning plate to move through the oil cylinder, so as to realize the two functions of positioning the pipe rod and avoiding the work space; but its positioning position is single and fixed, and cannot Meet the needs of different positioning positions for sucker rods and oil pipes.
