Abstract
The present invention discloses a kind of oil well depth and rope cable tensile force measuring device. Said measuring device includes upper supporting frame, lower supporting frame, upper driven wheel, lower driven wheel, measuring wheel, depth coder and weighing sensor. Said invention also provides their connection mode, and also provides the working principle of said measuring device and its operation method.
Description
Technical field
The invention belongs to the measurement mechanism field, relate to a kind of winch annex, be specifically related to a kind of with the degree of depth of cable measurement oil well and the measurement mechanism of the suffered pulling force of cable
Background technology
At present, when using cable (steel wire, wire rope or cable) that tool string (instrument or downhole tool) is lowered into when testing in the oil well, the degree of depth in the tool string lower going-into-well, be to obtain by the length of measuring cable, promptly the frictional force that moves through by cable drives measurement wheel, measure the revolution of measurement wheel,, obtain tool string and be lowered to the degree of depth in the oil well by the coefficient correction.And in the descending process of tool string, the tension force of cable can only be measured by an other cover tensioner, makes measurement mechanism comparatively complicated.
Summary of the invention
At the deficiencies in the prior art, purpose of the present invention just provides a kind of string of survey tool simultaneously and is lowered to the degree of depth in the oil well and the oil well depth and the cable pulling force winch metering device of the suffered pulling force of cable.
For achieving the above object, a kind of oil well depth of the present invention and cable pulling force winch metering device comprise upper bracket, lower carriage, last driven pulley, following driven pulley, measurement wheel, depth encoder and LOAD CELLS; Wherein, upper bracket links to each other with an end of lower carriage, the other end is equipped with LOAD CELLS, last driven pulley is installed on the upper bracket by main shaft, following driven pulley is installed on the lower carriage by countershaft, and the axis of last driven pulley and following driven pulley is parallel to each other, and measurement wheel links together by key and main shaft, one end of main shaft links to each other with depth encoder, and LOAD CELLS links to each other with the equipment of extraneous treatment circuit respectively with depth encoder.
Further, the equipment of described extraneous treatment circuit is single-chip microcomputer or memory.
Further, also comprise at least one contact roller, this contact roller is fixed on the described upper bracket, and the outer rim of this contact roller is corresponding with the outer rim of described measurement wheel.
Further, described contact roller is a pair of, and two contact rollers are separately positioned on the outer side edges of the wheel rim of described measurement wheel and last driven pulley.
Compared with prior art, oil well depth of the present invention and cable pulling force measurement device are in the oil well test process, tool string be can measure at any time and the degree of depth and the suffered pulling force of cable in the oil well are lowered into, accurate measurement, simple in structure, guaranteed the safety of test job.
Description of drawings
Fig. 1 is the front view of oil well depth of the present invention and cable pulling force winch metering device;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, oil well depth and cable pulling force winch metering device comprise upper bracket 1, lower carriage 2, last driven pulley 3, following driven pulley 4, measurement wheel 5, depth encoder 6 and LOAD CELLS 7.Upper bracket 1 is fixed together with bolt 9 with the left end of lower carriage 2, between the right-hand member of two stands 1 (2) LOAD CELLS 7 is installed.Last driven pulley 3 is installed on the upper bracket 1 by main shaft 8, and 5 of measurement wheels link together by key and main shaft 8, and an end of main shaft 8 is connected with depth encoder 6, has outer cover 10 on the depth encoder 6.Pair of pinch rollers 11 is separately positioned on the outer side edges of the wheel rim of measurement wheel 5 and last driven pulley 3, and two contact rollers 11 correspondence respectively compress measurement wheel 5 and last driven pulley 3, realizes compressing the effect of cable.Following driven pulley 4 is installed on the lower carriage 2 by countershaft 12, and the axis of last driven pulley 3 and following driven pulley 4 is parallel to each other, and LOAD CELLS 6 links to each other with the single-chip microcomputer in the external world respectively with depth encoder 7.Oil well depth and cable pulling force winch metering device are fixed on the flashboard 14 by clamp nut 13, and then are installed on the winch.
During actual measurement, at first cable is introduced from an end of measurement wheel 5,, drawn by last driven pulley 3 again, thereby form an assembly pulley around arriving driven pulley 4 down.During work, oil well depth and cable pulling force winch metering device are installed on the winch by flashboard 14, and the end that cable winds out end links to each other with tool string.When tool string was put into oil well, the pulling force of cable made assembly pulley produce pressure, and this pressure is delivered on the LOAD CELLS 7 by upper bracket 1 and lower carriage 2, and LOAD CELLS 7 is passed to signal on the extraneous single-chip microcomputer, can obtain the pulling force of cable.And tool string is when descending, and the degree of depth of tool string then is to obtain by the length of measuring cable, promptly drives measurement wheel in the cable motion process, and the revolution by depth encoder 6 record measurement wheels by the coefficient correction, obtains the depth of setting of tool string.Depth encoder 6 exports signal on the extraneous single-chip microcomputer too.
And two contact rollers 11 are installed in the outer rim place of measurement wheel 5 and last driven pulley 3, distance between driven pulley 3 reaches on contact roller 11 and the measurement wheel 5 can be regulated, with the degree that compresses of the cable on control 11 pairs of measurement wheels 5 of contact roller and the last driven pulley 3, thereby prevent that cable from jumping out race.
In addition, single-chip microcomputer also can substitute with memory, and the signal that memory is received is handled by single-chip microcomputer etc. then, obtains the corresponding cable degree of depth and pulling force numerical value.
