Description
(1) technical field
The utility model relates to and adopts optical means is the linear measure longimetry equipment of feature, particularly is a kind of oil pipe length measuring device.
(2) background technology
Oil pipe length measuring is simple the repetition and crucial work in the oil well operation process.Often forbidden to cause the operation failure, influenced the oil well ordinary production, caused economic loss because of oil pipe length measuring.Therefore, simplify the oil pipe length measuring process, it is very necessary to improve measuring accuracy.The classic method of measuring tubing length is that the oil pipe that takes out from oil well keeps flat on the ground, and with manually drawing steel tape to measure, not only work efficiency is low, and error is big.The exact position that instrumentation is measured subsurface tool also will be transferred once more in the oil field that has in oil well except that the human metering tubing length, check, and is loaded down with trivial details time-consuming again.Someone proposes the rectangular method of indirect survey based on the photoelectric coding principle, optical encoder sensor is installed on the wire rope of workover rig derrick traveling system, or is installed in well head, when tubing string is gone into the well " limit is measured, and calculate on the limit ".Though it is desirable in theory, in fact infeasible.Because of in tubing string is gone into the well process, unavoidable friction pulley skids, tubing string shake etc., can produce very big accidental error, and its full accuracy can only reach 1 ‰, if instrument deals with improperly, even causes the total data distortion.Patent documentation by retrieval, though the patent that associated length is measured has more than the tens of pieces of writing, wherein representational patent is 96220763,97225058,98209584,01,212,462 four pieces, all can not be directly used in oil pipe length measuring.
(3) summary of the invention
The purpose of this utility model provides a kind of distinguished oil pipe length measuring device, not changing oil pipe does not go into the well at the long operation habit of ground survey, obtain whole ground oil pipe natural length data with the optics horizontal metroscope, and handle by exclusive data interface and computing machine, calculate, analyze, the storage oil pipe is gone into the well length.Can improve oil pipe and survey farm labourer's effect, can improve the oil pipe length measurement precision again, solve oil pipe and survey long this technical barrier.
Above-mentioned purpose is realized by following technical proposals:
This device is made up of linear measure longimetry unit and data processing unit two large divisions.Linear measure longimetry unit wherein is made up of optics horizontal metroscope, detent mechanism, optical target board and oil pipe bracing frame.The optics horizontal metroscope is installed in above the detent mechanism.Detent mechanism is clamped in oil pipe male thread end.Optical target board is installed in oil pipe other end box thread end.The oil pipe bracing frame has two, all is installed in below the oil pipe.Data processing unit is made up of 6 volts of direct supplys, power module, laser emitting module, laser pick-off module, CPU center processor, storer and output interface circuit.6 volts of direct supplys are the power module power supply.Power module is transmitter module, receiver module, CPU power supply.Transmitter module, receiver module, storer and output interface circuit all are connected with CPU respectively, controlled by CPU.Storer also is connected with output interface circuit, and output interface circuit also is connected with computing machine.
Detent mechanism in the above-mentioned oil pipe length measuring device is made up of support, grip slipper and height control parts.Support is installed on the grip slipper, and grip slipper is clamped in oil pipe male thread end, height control parts and support together, the support upper top is installed the optics horizontal metroscope.
Technique scheme because of its ultimate principle is based on ligh-ranging, is not influenced by extraneous other factors after implementing, good stability, the data that record are true and reliable, and precision can reach 0.3 ‰, improve 10 times than manually measuring, improve 3～4 times, survey 20 times of long raisings than ultrasound wave than the photoelectric coding survey is long.The accurate location needs of going into the well of utensil when its length measurement precision satisfies workover treatment fully, and work efficiency improves than manually measuring greatly, and labour intensity reduces, and more helps civil operation and standardized administration.
(4) description of drawings
Accompanying drawing 1 is composition of the present utility model and mounting arrangement synoptic diagram.
Accompanying drawing 2 is data processing unit block schemes of the present utility model.
Among Fig. 1, the 1st, optics horizontal metroscope, the 2nd, detent mechanism, the 3rd, optical target board, the 4th, oil pipe bracing frame, the 5th, data processing unit, the 6th, computing machine.A is tested oil pipe.
(5) embodiment
As shown in Figure 1, this device is made up of linear measure longimetry unit and data processing unit two large divisions.The linear measure longimetry unit is made up of optics horizontal metroscope 1, detent mechanism 2, optical target board 3 and oil pipe bracing frame 4.Optics horizontal metroscope 1 is installed in above the detent mechanism 2.Detent mechanism 2 is clamped in the male thread end of oil pipe A.Optical target board 3 is installed in the other end box thread end of oil pipe A.Oil pipe bracing frame 4 has two, all be installed in oil pipe A below.Data processing unit is seen shown in Figure 2, is made up of seven parts.6 volts of direct supplys are the power module power supply.Power module can provide required several direct supplys, is respectively that each module provides working power among the figure.Laser emitting module, laser pick-off module, storer and output interface circuit all are connected with the CPU processor respectively, controlled by CPU.Storer also is connected with output interface circuit 5, and output interface circuit 5 also is connected with computing machine 6.
As seen from Figure 1, detent mechanism 2 is made up of support, grip slipper and height control parts.Support is installed on the grip slipper, and grip slipper is clamped in the male thread end of oil pipe A, height control parts and support together, the support upper top is installed optics and is surveyed long justice 1, its height and position can be adjusted.
The course of work of this device is: the oil pipe with length to be measured carries out high-pressure wash except that degreasing earlier, and puts neat on tubing rack.Again first oil pipe A being placed into bracing frame 4 gets on.Then detent mechanism 2 is clamped to fast the male thread end of oil pipe A, and optics horizontal metroscope 1 is fixedly installed to the upper top of detent mechanism 2, optical target board 3 places the other end box thread end of oil pipe A.Open optics horizontal metroscope 1, press and survey long button, then launch a branch of column of red light, a hot spot on optical target board 3, occurs, adjust detent mechanism 2 and make optics horizontal metroscope 1 and oil pipe A parallel axes, and hot spot is in the center of light target 3.After first oil pipe mixes up, generally no longer adjust.Laser emits from optics horizontal metroscope 1 and arrives optical target board 3, reflects from optical target board 3 again, is received by optics horizontal metroscope 1, and the length of required back and forth time with oil pipe A is directly proportional, and has obtained the length information of every oil pipe thus.These length informations are collected through data processing unit 5, processing, calculate, and obtain single, the cumulative data of tubing length, store on request, demonstration, printing as a result etc. again.During off-line, can finish data and download, generate the tubing length form by communication interface and computing machine 6 communications.Can also realize that data report in the LAN (Local Area Network), the inquiry of historical data etc.
