Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Fig. 1 to 5, the complementary coiled tubing counter of dual signal of the application, mainly comprises pipe guide device 6, upper counting assembly 1, lower counting assembly 5 and support bar 4 and forms.
Pipe guide device 6 mainly comprises upper shell 6-3, lower house 6-1 and righting wheel 6-2 and forms, be hinged between upper shell 6-3 and lower house 6-1, righting wheel 6-2 is 4, upper shell 6-3, lower house 6-1 respectively install 2, and be arranged symmetrically with, righting wheel 6-2 makes to keep more straight state through the coiled tubing of counter portion, thus it is more stable that the first measuring wheel 11 and the second measuring wheel 14 are contacted with coiled tubing when measuring, and is easier to measure.
Upper counting assembly 1 mainly comprises counting assembly shell 8, first measuring wheel 11 (girth 0.5m), primary axis 12 and secondary axle 13, minor sprocket 10 and hinge wheel 9 (ratio of gear 1:2), the installation position 2 of the first scrambler and mechanical counter installation position 7, wherein, first measuring wheel 11, first scrambler and minor sprocket 10 are coaxially installed on primary axis 12, hinge wheel 9 and mechanical counter are coaxially installed on secondary axle 13, are Chain conveyer between hinge wheel 9 and minor sprocket 10.
Lower counting assembly 5 mainly comprises lower counting assembly shell 15, second measuring wheel 14 (girth 0.5m), the installation position 3 of the second scrambler and axle, and the second measuring wheel 14 and the second scrambler are coaxially installed on this axle.
Upper counting assembly 1 is connected by pin with the upper shell 6-3 of pipe guide device, lower counting assembly 5 is connected by pin with the lower house 6-1 of pipe guide device, when measuring, upper counting assembly 1 is connected to the upper shell 6-3 of pipe guide device 6 by spring, thus is pressed on coiled tubing, simultaneously, lower counting assembly 5 is also linked together by spring and upper counting assembly 1, thus in the vertical direction, clamping coiled tubing, thus provide condition for reducing measuring error when measuring.
Measuring process:
Due to the reason of spring (connection counting the spring of the upper shell 6-3 of assembly 1 and pipe guide device 6) and self gravitation, first measuring wheel 11 of upper counting assembly 1 is pressed on coiled tubing, and due to the reason of spring force (spring connection counting assembly 1 and lower counting assembly 5 produces), second measuring wheel 14 of lower counting assembly 5 is also pressed on coiled tubing, and the first measuring wheel 11 and the second measuring wheel 14 clamp coiled tubing in the vertical direction.
Measure time, coiled tubing through pipe guide device 6 to down-hole motion or go out well, then drive the first measuring wheel 11 and the second measuring wheel 14 to move forward or backwards.
Wherein the first measuring wheel 11, coaxial mounted minor sprocket 10 and the first scrambler is driven to rotate, first scrambler exports the first measuring-signal, and minor sprocket 10 drives the hinge wheel 9 on secondary axle 13 by chain (ratio of gear 1:2), thus drive coaxial mounted mechanical counter on secondary axle 13, thus making measuring wheel rotate a circle, mechanical counter adds 1, thus the coiled tubing that staff can directly directly be read now by mechanical counter in pulpit enters well depth.
Wherein the second measuring wheel 14, drive coaxial mounted second scrambler to rotate, export the second measuring-signal, this is measuring process, is next being signal processing, and from two measuring-signals, what analytical Calculation went out coiled tubing enters well depth.Principles of signal processing:
Incremental encoder converts displacement to periodic electric signal, then this electric signal is transformed into count pulse, represents the size of displacement by the number of pulse.
Incremental encoder rotates a circle, can export fixed number pulse (scrambler of different accuracy can be selected according to field demand, if error requirements is little, then this export umber of pulse more.This sentences M is example, namely scrambler rotates a circle, output signal is M umber of pulse, then the coiled tubing length now representated by individual pulse is 0.5/M rice), it judges that the principle in direction is according to advanced or delayed relatively the judging of INA and INB signal.
Use single-chip microcomputer, first scrambler and the second scrambler are obtained respectively measuring-signal to input to single-chip microcomputer simultaneously and process, processing procedure is, with single-chip microcomputer count the first measuring-signal through 5 (this number also will according to site error require determine, if accuracy requirement is high, then this number is selected as well less) complete pulse number is chronomere, synchronous counting is in this chronomere, and the second measuring-signal is through how many (being set to N herein) individual rising edges or negative edge.
Then compare in single-chip microcomputer inside, work as N<=5, then obtaining result is in this chronomere, obtains 5 pulses after coiled tubing motion; Work as N>5, then obtaining result is in this chronomere, obtains N number of pulse after coiled tubing motion.
Then count next chronomere (below the first measuring-signal 5 complete pulse numbers), so continue, thus continue to carry out measuring process.Meanwhile, (5 or N) are added up to the umber of pulse obtained in each chronomere before.
Then, by the arithmetic element of single-chip microcomputer inside, the overall pulse number T that in the continuous time according to cumulative acquisition, (each chronomere cumulative forms) obtains, resolve obtain now coiled tubing enter well depth L=overall pulse number T*0.5/M rice.(now by visualization model, connect display, be installed on by display in pulpit, the coiled tubing that staff can be made to get information about now enters well depth).
About signal processing:
Situation 1: suppose that relative sliding does not occur the first scrambler, no matter whether the second scrambler there is relative sliding, second scrambler in the time B time period, is metered at most 5 rising edge of a pulses or negative edge (i.e. <=5) at time A; As shown in Figure 6, though the signal of the signal of the second scrambler and the first scrambler synchronously, relative advanced, when relatively lagging behind, under relative sliding situation does not occur the first scrambler, the rising edge of a pulse that the second scrambler is metered into or negative edge number are no more than the complete pulse quantity that the first scrambler is metered into.Then in this period, the length that coiled tubing is passed by is the length of 5 pulses.
Situation 2, as shown in Figure 7, supposes the first scrambler generation relative sliding, still measures the first scrambler and passes by 5 burst lengths, the rising edge of a pulse that the second scrambler measures or negative edge number N.
1) if relative sliding does not occur the second scrambler, then N>=5, then the distance that in this time period, coiled tubing is passed by is N number of pulse length;
2) if the second scrambler generating portion is slided, but N>=5, the distance of now still passing by according to coiled tubing is N number of pulse length;
3) if a large amount of slip occurs the second scrambler, N<=5, the distance of now passing by according to coiled tubing is 5 pulse lengths.
Under situation 2 situation, especially there is relative sliding in the first scrambler and the second scrambler simultaneously time, the rising edge of a pulse of being passed by by the signal measuring the signal complete pulse quantity of passing by and the second scrambler comparing the first scrambler or the quantity of negative edge, according to more umber of pulse measuring and calculating coiled tubing length, thus (relative sliding is little to reduce certain error in dipping, in time period, the rising edge of metering is many, more close to the physical length of coiled tubing).
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
