Abstract
The utility model provides the utility model discloses an oil pipe friction coefficient test device includes rack frame, supporting component, oil pipe grip block and oil pipe connector in succession, and rack frame and supporting component are fixed in subaerially, draws and presses hydraulic cylinder, centre gripping hydraulic cylinder to pass through flange joint with the rack frame, it is drawing between pressure hydraulic cylinder and the oil pipe connector to draw the pressure sensor to install, pressure sensor installs between centre gripping hydraulic cylinder and grasping system, the oil pipe grip block is installed in the grasping system recess. The utility model provides the high reliable degree of fill head design has reduced the risk of fill head work to oilfield on -site use to coiled tubing has fine actual directive significance, when the required different clamp forces of the oil pipe of difference, only mated increase of need or reduction clamping system and clamping cylinder quantity can.
Description
Technical field
This utility model belongs to oil equipment, is related specifically to the test device for coiled tubing coefficient of friction.
Background technology
During continuous oil pipe device operation, injection head as entering and rise the critical component of producing well under coiled tubing, hoisting and offer power be provided for coiled tubing.Injection head is that the normal pressure provided by multipair clamping cylinder on injection head produces for the frictional force of lower oil tube, and normal pressure is pressed on fixture block by rolling bearing, and then holds oil pipe tightly.Determine that oil pipe coefficient of friction accurately designs that to meet the clamping cylinder of actual job needs be the key that can injection head properly functioning.Mostly current conventional use of coefficient of friction is theoretical derivation or empirical value, lacks actual argument means, it is impossible to as the reference frame of injection head design.
Summary of the invention
The purpose of this utility model is to provide a kind of experimental provision for coiled tubing friction coefficient measurement, and this device measures the coefficient of friction needed for coiled tubing moves by simulation actual job situation, designs the practicable theoretical foundation of offer for injection head.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of for coiled tubing testing device for friction coefficient, including rack frame, a support component, oil pipe grip block and oil pipe connector, rack frame and a support component are fixed on ground, it is characterised in that: tension and compression fluid cylinder, clamping fluid cylinder pass through Flange joint with rack frame；Tension-compression sensor is arranged between tension and compression fluid cylinder and oil pipe connector；Pressure transducer is arranged between clamping fluid cylinder and grasping system；Oil pipe grip block is installed in grasping system groove.
The beneficial effects of the utility model are:
1, the coiled tubing friction co-efficient value drawn by measurement apparatus measurement, improves the reliability of injection head design, reduces the risk of injection head work, and the Oil Field use to coiled tubing has well actual directive significance；
2, needed for different oil pipes during different clamping force, what only need were paired is increased or decreased clamping system and clamping cylinder quantity.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model top view.
Detailed description of the invention
1,2 further illustrate detailed description of the invention of the present utility model below in conjunction with the accompanying drawings.
See Fig. 1-2: rack frame 1 and a support component 2 is individually fixed on ground, tension and compression fluid cylinder 4, clamping fluid cylinder 5 pass through Flange joint with rack frame 1, tension-compression sensor 6 is arranged between tension and compression fluid cylinder 4 and oil pipe connector 10, and oil pipe connector 10 is connected with test oil pipe 8；Pressure transducer 7 is arranged between clamping fluid cylinder 5 and grasping system 3, and oil pipe grip block 9 is installed in the groove of grasping system 3.When testing device work, tension and compression fluid cylinder 4 applies pressure or thrust to test oil pipe 8, test oil pipe 8 is made to produce the trend of relative motion, clamping fluid cylinder 5 applies clamping force, oil pipe is held tightly by producing normal pressure on test oil pipe 8 surface after grasping system 3 and grip block 9, along with being continuously increased of thrust, when oil pipe is changed into critical kinestate by resting state, the coefficient of friction recorded is the actual friction co-efficient value of oil pipe.The quantity of grasping system 3 and clamping oil cylinder 5 can be increased or decreased in pairs by clamping force size.
