Abstract

The invention relates to the technical field of petroleum well repair auxiliary equipment, in particular to an on-line length measuring and positioning device for a pipe rod in an oil field well repair integrated catwalk and a using method. According to the technical scheme, a bottom frame is fixed to a catwalk base, a positioning shaft part is installed on the bottom frame, a rotating frame capable of rotating around the positioning shaft part is installed on the positioning shaft part, a response plate is installed on the rotating frame, and the response plate can rotate around a first rotating shaft on the rotating frame; the positioning shaft part is hinged to the first connecting rod, the first connecting rod is hinged to the second connecting rod, and the second connecting rod is installed on the rotating shaft and can rotate around the rotating shaft; the second connecting rod is connected with an oil cylinder, the oil cylinder is connected with an oil cylinder installation frame, and the oil cylinder installation frame is installed on the catwalk. The device has the beneficial effects that the structure is compact, positioning is accurate, the avoiding space is large, catwalk operation is not affected, in addition, the device is integrated with a pipe rod lifting operation device of a catwalk, the multiple carrying links of a pipe rod are omitted, the operation efficiency is improved, and the labor intensity is relieved.

Description

technical field [0001] The invention relates to the technical field of petroleum workover auxiliary equipment, in particular to an on-line length measurement and positioning device for pipe rods in an integrated catwalk in an oil field workover and a use method thereof. Background technique [0002] 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...
