Description

Continuous-tube ovality on-line measuring device
Technical field
The utility model relates to a kind of continuous-tube ovality on-line measuring device, belongs to the oil field and uses continuous-tube online measuring technique field.
Background technology
Continuous-tube is one of core of continuous-tube technology, generally is wrapped on the above reel of diameter 1m to store.Continuous-tube is in state of plastic deformation all the time in a life cycle, namely will be through three straight-curved and three curved-straight distortion.During work, continuous-tube will be subject to friction and interior external pressure and the Axial Loads of extruding, preventer and the borehole wall of injector head grip block, prolongation along with service time, the ovality of continuous-tube can increase gradually, when reaching certain value, can hinder it by injector head and preventer, cause the continuous-tube operational failure.
At present, the complete dependence on import of the checkout equipment of continuous-tube ovality and technology, the domestic blank that still belongs to.Existing main detection method is the eddy displacement sensor detection method, be the detection needs (distance of reaction of general eddy displacement sensor is 0.3mm-4.3mm) that satisfy eddy displacement sensor, external eddy displacement sensor from the continuous-tube outer tube wall very close to, and the external diameter of continuous-tube is very little, and the number of sensors of each cell layout can be restricted.For fear of the phase mutual interference between the eddy displacement sensor, foreign technology is spaced apart with the large distance of each annular detecting unit, and the result is the accuracy that greatly reduces the data acquisition of continuous-tube ovality, and impact detects effect.
Summary of the invention
The purpose of this utility model is to provide a kind of continuous-tube ovality on-line measuring device, it utilizes the design of continuous-tube diameter displacement induction mode, make device construction compacter, thus the accuracy that improve to detect, for use and the management of continuous-tube provides scientific basis.
Concrete technical scheme of the present utility model is as follows:
The inner barrel of this pick-up unit and outer cylinder body form by upper and lower two and half cylindrical shells.The hole enlargement bar that connects wear-resisting head and suit holddown spring is located in the inner barrel barrel radial hole, and hole enlargement bar tail end is aimed at the eddy displacement sensor that is located in the outer cylinder body barrel radial hole.The hole enlargement bar evenly distributes along the inner barrel periphery, and the equal radial compaction of its wear-resisting head is on the continuous-tube periphery.
Fixedly running roller is fixed on top, outer cylinder body two sides.Fixed head is connected in outer cylinder body bottom outer wall, and the running roller that floats is connected on the fixed head by bearing pin and Compress Spring, and continuous-tube then is supported on fixedly between the running roller and unsteady running roller.The running roller that floats connects the rotary encoder that is located on the fixed head by shaft coupling.
Wear-resisting head connects the hole enlargement bar and is pressed on the continuous-tube surface by holddown spring, the vary in diameter of continuous-tube is conducted to the hole enlargement bar by wear-resisting head, make the hole enlargement bar in inner barrel barrel radial hole, produce slip, the change in displacement signal is passed to the eddy displacement sensor of its tail end, make eddy displacement sensor sense in real time the vary in diameter of continuous-tube.The method is equivalent to the continuous-tube diameter is amplified to hole enlargement bar tail end, and sensitive surface is increased greatly along with the prolongation of diameter, thereby has expanded the arrangement space of eddy displacement sensor.
The circumferential arrangement space that the utility model utilizes continuous-tube hole enlargement bar to increase eddy displacement sensor makes the layout of sensor compacter, and the testing result of ovality is more accurate, the installation of equipment and use more conveniently, and the data that read are more directly perceived.When the continuous-tube operation, this pick-up unit can carry out real-time online to the ovality of each section continuous-tube and detect, and does not affect working rig work, for the performance index of continuous-tube and life-span are judged important evidence is provided.

Embodiment
Further specify referring to figs. 1 through 3 couples of embodiment of the present utility model:
Embodiment:
The inner barrel 6 of this pick-up unit is connected with outer cylinder body by two upper and lower half cylindrical shells compositions of pivot pin connection.The hole enlargement bar 7 that connects wear-resisting head 4 and suit holddown spring 5 is located in the inner barrel 6 barrel radial holes, and hole enlargement bar 7 tail ends are aimed at the ZA-GA05-11-075-001-00 eddy displacement sensor 8 that is located in the outer cylinder body 9 barrel radial holes.Hole enlargement bar 7 and ZA-GA05-11-075-001-00 eddy displacement sensor 8 evenly distribute along the cylindrical shell periphery, and its wear-resisting head 4 equal radial compactions are on continuous-tube 3 peripheries.
Fixedly running roller 13 is bolted on top, outer cylinder body 9 two sides.Fixed head 12 is connected in outer cylinder body 9 bottom outer walls by bolt, and the running roller 10 that floats is connected on the fixed head 12 by bearing pin 14 and Compress Spring 11, and 3 of continuous-tubes are supported on fixedly between the running roller 13 and unsteady running roller 10.The running roller 10 that floats connects the E6B2-CWZ3E rotary encoder 1 that is located on the fixed head 12 by shaft coupling 2.
