The method provided by the invention is simple to operate, high in measurement efficiency and more accurate in result.
Description
Technical field
The present invention relates to the logging technique field, be specifically related to a kind of method of crossing the Measurement accuracy degree of depth in the drill bit well logging.
Background technology
Along with the development of logging technique, new method, new instrument are promoted application gradually.Recent years, the drill-over logging technique has been attained maturation, crosses the drill bit logging technique substantially to have replaced common well logging and well logging during, becomes logging operation common technology means.
In drilling well, well logging is crossed in the drill bit during well logging, and all needing has accurately depth survey, does not have the accurately degree of depth, and the measurement of downhole instrument is with regard to few of meaning.Traditional depth survey all is to need the number of turns, the diameter of cylinder on cylinder of restricting by the large rope of measurement diameter, greatly, and a plurality of factors such as position of the layer at current large rope place fathom; And actual measurement intermediate roll sensor can only provide to have turned how much spend this parameter, and displacement will provide in conjunction with above-mentioned said parameters, because need the parameter of measurement more, it is all lower to cause measuring efficient and accuracy rate, and it is higher to measure cost.
Method as herein described is to measure by measuring on the large rope lines, directly can access shift value, because large rope is to be worked out by multiply, the centre has scraggly lines, can detect lines by optical transmitting set and optical receiver, then optical signal is converted into pulse signal, such pulse just can represent one section nominal distance.Obtaining the hook shift value by the identification pulse code at last.
Summary of the invention
The electromagnetic transmission method that the object of the invention is to propose a kind of logger information is crossed the method for the Measurement accuracy degree of depth in the drill bit well logging, solved drilling well, well logging and crossed in the drill bit well logging depth survey parameter more, program is complicated, and measures efficient and the low problem of accuracy rate.
For reaching this purpose, the present invention by the following technical solutions:
Cross the method for the Measurement accuracy degree of depth in the drill bit well logging, during logging operation, the action of lower drilling rod is successively: elevator put drilling rod, on carry drilling rod and move on well mouth drill place, the hydraulic tongs button to, transfer drilling rod, put slips, discharge elevator and go up the lifting card at last, the installation rate sensor is monitored the vibrations of two instruments on hydraulic tongs and elevator, during the vibrations sudden change, be elevator and embrace drilling rod and upper button, behind complete button on the hydraulic tongs, begin to calculate the hook displacement, until till the release elevator, this segment distance is the degree of depth of going into the well;
Detect the lines of the large rope of well logging by light pulse transmitter and light pulse receiver, afterwards the optical signal that records is converted into pulse signal, the pulse code that obtains is identified, obtained button on the hydraulic tongs to the shift value that discharges hook during the elevator, and then draw the shift value of depth of falling well.
When detecting the large rope figure of well logging road, survey reflective power by two light pulse transmitters and two fixing light pulse receivers of spacing, to identify the space between the two strand thighs; In large rope drawing process, calculate the actual range of large rope by counting void meter, determine the moving direction of large rope by the reception sequential of two light pulse receivers.
Described light pulse transmitter is to light pulse signal of the large rope figure of target road emission, by electric impulse signal of light pulse receiver output behind the feedback circuit, the electronic gate of opening in the circuit module begins to count by counting circuit by time oscillation device action generation pulse; Light pulse is got back to receiver after being reflected by target, electric pulse of the same generation of receiver, close the pulse that electronic gate termination time oscillator produces and pass through, thereby arrive target and just can calculate the corresponding time interval by the umber of pulse that the target diffusion turns back to receiving system and calculate target range by measuring light pulse.
Method of the present invention is measured by measuring on the large rope lines, directly can access shift value, can detect lines by optical transmitting set and optical receiver, then optical signal is converted into pulse signal, such pulse just can represent one section nominal distance, obtaining the hook shift value by the identification pulse code at last, this method is simple to operate, and measurement efficient is high, the result is more accurate.

Among the figure: 1, time oscillator; 2, light pulse transmitter; 21, the first incident light; 22, the second incident light; 3, light pulse receiver; 31, the first retroreflection light; 32, the second retroreflection light; 4, feedback circuit; 5, circuit module; 6, counting shows output; 7, the shallow bid of restricting greatly; H, gap.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Cross the method for the Measurement accuracy degree of depth in the drill bit well logging, during logging operation, the action of lower drilling rod is successively: elevator put drilling rod, on carry drilling rod and move on well mouth drill place, the hydraulic tongs button to, transfer drilling rod, put slips, discharge elevator and go up the lifting card at last, the installation rate sensor is monitored the vibrations of two instruments on hydraulic tongs and elevator, during the vibrations sudden change, be elevator and embrace drilling rod and upper button, behind complete button on the hydraulic tongs, begin to calculate the hook displacement, until till the release elevator, this segment distance is the degree of depth of going into the well.
As shown in Figure 1 and Figure 2, h is the gap between large rope two shallow bids.Two light pulse transmitters 2 and light pulse receiver 3 are set, two light pulse transmitter 2 each spontaneous emission the first incident light 21 and second incident lights 22, corresponding two light pulse receivers receive respectively the first retroreflection light 31 and the second retroreflection light 32 afterwards, survey reflective power to identify large rope two shallow bid gap h by two each and every one light pulse transmitters and two light pulse receivers, spacing is fixed between 2 light pulse receivers, in large rope drawing process, judge the direction that large rope moves by the sequential that two light pulse receivers 3 receive retroreflection light.
Detect the lines of the large rope of well logging by light pulse transmitter 2 and light pulse receiver 3, afterwards the optical signal that records is converted into pulse signal, the pulse code that obtains is identified, obtained button on the hydraulic tongs to the shift value that discharges hook during the elevator, and then draw the shift value of depth of falling well;
