Abstract
The invention belongs to oil well measuring mechanical equipment and discloses an oil tube measuring instrument for an oil well. The oil tube measuring instrument comprises a pulley, a pulley base, a coder, a movable sensor, a spring device and a cylinder. The vertical cylinder is provided with a pulley track, the pulley is installed on the pulley base, a pulley shaft is erected on the pulley track, and the pulley base is connected with the spring device. The pulley is provided with the coder and the movable sensor. The coder and the output ends of the movable sensor are connected with a measuring device. According to the measuring instrument, an oil tube can be prevented from being blocked in the descending process, the working efficiency is improved, and the labor cost is reduced.
Description
Technical field
The invention belongs to well measurement plant equipment, particularly a kind of oil pipe measuring instrument for oil well.
Background technology
Present each elephant play the measurement of oil pipe or run of steel to be all save measurements by well head work ruler one, be then recorded on book last wait oil pipe or drilling rod under completely often connect according to what record the total length that tubing length and oil pipe hoop number determine played oil pipe or drilling rod afterwards.This methods were both lost time, and needed again at least two well head work recorders.And also can run into oil pipe in the middle of the process of lower oil pipe and to be hampered the situation of (oil pipe can not go down smoothly in sleeve pipe), this just needs to rise out again after drifting again by relevant, and so just likely previous writing task is all wasted or recording data mixes up.
Summary of the invention
In order to solve prior art Problems existing, the object of the present invention is to provide a kind of oil pipe measuring instrument for oil well, can avoid being hampered in lower Tubing During Running situation, increasing work efficiency, reduce labour cost.
In order to achieve the above object, the present invention is achieved by the following technical solutions.
A kind of oil pipe measuring instrument for oil well, it is characterized in that, comprise pulley, pulley base, encoder, movable sensor, spring assembly and cylindrical drum, described vertical circular column casing is provided with pulley track, pulley is installed on pulley base and pulley spindle is erected on pulley track, pulley base linking springs device; Described pulley is equiped with encoder and movable sensor, each output of encoder and movable sensor is connected with measurement mechanism.
Feature of the present invention and further improvement are:
Described spring assembly comprises spring and spring support, and spring installing is with on spring support, and spring support is fixed in cylindrical drum, and spring one end is connected on pulley base.
The cylindrical drum of described pulley right opposite is equiped with magnetic induction coil.
Described cylindrical drum one end is provided with flange.
Compared with prior art, this practicality has technique effect significantly.
This product is used for the length that lower oil pipe is measured in oil field, can reduce the quantity of required well head work, also can reduce error, make to measure actual tubing length more laborsaving more accurate.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the overall schematic of a kind of oil pipe measuring apparatus for oil well of the present invention.
In figure: 1, spring support; 2, pulley; 3, pulley base; 4, spring; 5, magnetic induction coil; 6, cylindrical drum.
Detailed description of the invention
As shown in Figure 1, a kind of oil pipe measuring instrument for oil well, comprise pulley 2, pulley base 3, encoder, movable sensor, spring assembly and cylindrical drum 6, described vertical circular column casing 6 is provided with pulley track, pulley is installed on pulley base 3 and pulley spindle is erected on pulley track, pulley base linking springs device; Described pulley is equiped with encoder and movable sensor, each output of encoder and movable sensor is connected with measurement mechanism.
Wherein, spring assembly comprises spring 4 and spring support 1, and spring 4 is installed with on spring support 1, and spring support 1 is fixed in cylindrical drum 6, and spring 4 one end is connected on pulley base 3.
Wherein, the cylindrical drum 6 of pulley 2 right opposite is equiped with magnetic induction coil 5.
Wherein, cylindrical drum 6 one end is provided with flange.
The oil pipe measuring instrument operating principle for oil well of the present embodiment is as follows.
First with bolt, the bolt hole of measuring instrument by lower bottom base is fixed on wellhead flange when measuring tubing length.After oil pipe enters measuring instrument inside, meter wheel is just tightly pressed in oil pipe surface by the thrust of spring 4, when oil pipe moves downward, meter wheel rotates counterclockwise, when oil pipe moves upward, meter wheel rotates clockwise, at this moment the encoder be arranged on meter wheel just can pass to ground system the number of turns that meter wheel rotates by electric pulse, and ground system just can by the length calculating oil pipe motion of number of pulses.When the hoop on oil pipe moves to meter wheel, meter wheel can be pushed up backward, displacement transducer upwards can be pushed up when meter wheel rearward moves.Just can measure whether there is hoop process by displacement transducer amount of movement upwards, and record is through hoop number.But oil pipe can swing in measuring instrument inside when actual measurement, it is have hoop to pass through that displacement transducer can be made to think by mistake, so we also added a magnetic induction coil 5 on the position that meter wheel is just right, judge that the movement of displacement transducer is caused because of having hoop process or oil pipe to swing when there being hoop through the magnetic flux difference that out-of-date response is generations by oil pipe is different with the diameter of hoop by magnetic induction coil 5.
Although be below described embodiment of the present invention by reference to the accompanying drawings, the present invention is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of manual, and when not departing from the scope that the claims in the present invention are protected, can also make a variety of forms, these all belong to the row of the present invention's protection.
