The continuous oil pipe weight indicator comprises a sensor, an indicator head, an indicator core and an indicator dial; the indicator core and the indicator dial are installed inside the indicator head; weight numerical values are arranged at the circumferential edge of indicator dial; a bottom end of the indicator head is provided with a connecting head; an indicator portion which is arranged between the connecting head and the indicator core is provided with a damper; the connecting head is communicated with the damper. The continuous oil pipe weight indicator has the advantages of being simple in structure, convenient to install, stable and reliable in performance and high in accuracy, enabling check to be convenient, solving the problems that the traditional weight indicator product is high in cost, a pointer is easy to misread during working and accordingly engineering accidents occur and being particularly applicable to continuous oil pipe weight indicating during oil well testing operation.
Description
Technical field
The utility model relates to a kind of coiled tubing weight indicator, belongs to oil test instrumentation technical field.
Background technology
Coiled tubing technology has been widely used in oil well test field, and in oil-gas exploration and exploitation, plays a part very important.At present domestic traditional weight indicator of using in continuous oil pipe operation process needs two sensors to detect well and lower log signal, and on Displaying Meter, also needs two pointers to carry out numerical value demonstration (also claiming two pointers two pressure transmission bag weight indicators).Need two load by injection head upwards play well pulling force weight and the weight of going into the well downwards converts hydraulic pressure signal to.Hydraulic pressure signal again by hydraulic line by signal leading weight indicator, weight indicator receives after signal, shows its actual weight by certain proportion.So not only increase product cost.And also easily there is the engineering accident causing because misunderstanding pointer at work.Therefore, be necessary to research and develop one and conveniently check and installation and maintenance, and can reduce the weight indicator of product cost.
Summary of the invention
The purpose of this utility model is: a kind of simple in structure, convenient installation is provided, and stable and reliable for performance, precision is high and be convenient to check, high to solve traditional weight indicator product cost, and easily misunderstands at work the coiled tubing weight indicator of pointer problem.
The technical solution of the utility model is:
A kind of coiled tubing weight indicator, comprise sensor, gauge outfit, watch core and dial plate, watch core and dial plate are housed in gauge outfit, the circumferential edges of dial plate is provided with weight numerical value, it is characterized in that: gauge outfit bottom is provided with connector, in gauge outfit between connector and watch core, be provided with damper, connector is communicated with damper; Described watch core is made up of pointer, needle pivot, C type pipe, connector and sector gear, and sector gear and pointer are housed on needle pivot, and the periphery of needle pivot is provided with C type pipe, and one end of C type pipe is communicated with damper.The other end of C type pipe is connected with sector gear by connector, is provided with dial plate zeroing fluted disc in the gauge outfit of damper one side, and dial plate zeroing fluted disc and dial plate are connected with a joggle.Described sensor is communicated with connector by hydraulic line.
The utility model has the advantage of:
This coiled tubing weight indicator is simple in structure, convenient installation, stable and reliable for performance, and precision is high and be convenient to check, solved traditional weight indicator product cost high, and easily misunderstands pointer at work and cause the problem of engineering accident.Being specially adapted to coiled tubing in oil well test operation refers to heavily use.

Detailed description of the invention
This coiled tubing weight indicator comprises sensor 1, gauge outfit 2, watch core and dial plate 3, and watch core and dial plate 3 are housed in gauge outfit 2, and the circumferential edges of dial plate 3 is provided with weight numerical value 4.Gauge outfit 2 bottoms are provided with connector 5, in the gauge outfit 2 between connector 5 and watch core, are provided with damper 6, for adjusting the pressure size of hydraulic oil.Connector 5 is communicated with damper 6.
Watch core is made up of pointer 7, needle pivot 8, C type pipe 9, connector 10 and sector gear 11, and sector gear 11 and pointer 7 are housed on needle pivot 8, and the periphery of needle pivot 8 is provided with C type pipe 9, and one end of C type pipe 9 is communicated with damper 6; The other end of C type pipe 9 is connected with sector gear 11 by connector 10.In the gauge outfit 2 of damper 6 one sides, be provided with dial plate zeroing fluted disc 12, dial plate zeroing fluted disc 12 is connected with a joggle with dial plate 3.
The sensor 1 of this coiled tubing weight indicator is arranged on coiled tubing injection head below by connecting screw rod, and sensor 1 is also communicated with connector 5 by hydraulic line.When work, first on injection head, apply a downward pressure to sensor 1, make sensor 1 inside have pressure, then rotate dial plate 3 pointer 7 is made zero by the dial plate fluted disc 12 that returns to zero, in the time that Operation Tubing Aggregate is gone into the well downwards, injection head is exerted pressure sensor 1 downwards, pressure is connected to by hydraulic line and connector 5 on the damper 6 of weight indicator, damper 6 is connected with the C type pipe 9 of weight indicator inside, after C type pipe 9 is under pressure, producing the Zona transformans part 10 that is dynamically connected moves, connector 10 drives sector gear 11 to rotate, sector gear 11 drives needle pivot 8 to rotate, thereby drive pointer 7 to rotate, pointer 7 indicates the weight while going into the well downwards on dial plate 3.In the time that Operation Tubing Aggregate upwards plays well, injection head is upwards mentioned, at this moment sensor 1 starts to discharge the preestablished pressure to it while starting working most, when after pressure decreased, C type pipe 9 is out of shape, and drives connector 10 to drive sector gear 11 to rotate, and sector gear 11 drives needle pivot 8 to rotate, thereby drive pointer 7 to rotate, pointer 7 indicates the weight while upwards pulling out well on dial plate 3.Weight instruction when completing coiled tubing and go into the well by a pointer 7 thus and while going out well.This coiled tubing weight indicator is simple in structure, stable and reliable for performance, and precision is high, be convenient to check, has solved traditional weight indicator product cost high, and easily misunderstands pointer at work and cause the problem of engineering accident.Being specially adapted to coiled tubing in oil well test operation refers to heavily use.
