Description
Technical Field
The invention relates to the technical field of measurement, in particular to a system for measuring cable guide, cable running depth and tension in oil field logging.
Background
The depth information is very important information in petroleum logging, and the depth data can truly reflect the bottom layer information of the oil and gas well only by corresponding to geological parameters (well deviation azimuth, lithology, porosity and the like) measured by an underground instrument one to one. Therefore, the reliability and the accuracy of the depth data are very important for obtaining high-quality logging information at the later stage. In the petroleum logging industry, according to different transmission modes of measurement signals, the method can be divided into cable logging, logging while drilling and downhole storage logging. The cable logging is the most common logging mode used at present because of the advantages of more diversified logging projects, relatively simple construction conditions, high quality of obtained logging data and data, good reliability and the like.
Currently, the most widely used depth measurement device in wireline logging is martindac. The Martindka depth measurement system is a depth measurement device widely applied in the current cable logging, and the core component of the Martindka depth measurement system is a depth wheel. During logging, the length of the cable is converted into the number of rotation turns of the depth wheel, so that the depth of the underground measuring equipment can be obtained in real time. Different depths correspond to different logging information (such as resistivity, porosity and the like), so the accuracy and reliability of the depth information are very important for obtaining high-quality logging information at a later stage. The existing logging cable measurement system has the following two outstanding problems:
1) in the logging process, the surface of the depth wheel is abraded due to the fact that the depth wheel is in long-term contact with the cable, the circumference of the depth wheel is changed, the movement distance of the cable corresponding to pulses output by the photoelectric encoder on the depth wheel is also changed, and accordingly the depth information is accumulated to be wrong. In actual use, the service life of the depth wheel is generally 6 months, and the depth wheel should be corrected later, otherwise, the depth data can be deviated, and the analysis of the later logging data is influenced. As the depth wheel usage frequency is higher, the correction period will also be shorter.
2) The pulley for guiding the logging cable, the martindac for measuring the running depth of the cable, the tensiometer for measuring the tension of the logging cable and the pickup of the magnetic mark of the logging cable are adopted, and a split measuring instrument (structure) is adopted, so that the volume is overlarge, the operation is troublesome, the measurement is not accurate, and the operation cost is high.
Therefore, how to design a measurement system for cable guiding, cable running depth and tension in oil field logging with accuracy, reliability and controllable operation cost becomes a technical problem to be solved urgently.

Fig. 2 is a schematic structural diagram of the arc pulley measuring device of the present invention. The arc pulley measuring device (wellhead martindac) comprises an oil remover 1, a centering wheel 2, a guide wheel 3, a jump-proof wheel 4, a metering wheel 5, a wireless signal transmission module 6, a magnetic marker 7 (magnetic signal sensor), a photoelectric encoder 8, a left clamping plate 9, a right clamping plate 9, a pinch roller 10, a tension meter 11 (tension sensor), a connecting lug 12 and an arc pulley controller (not shown).
Fixing the engaging lug (12) of the arc-shaped pulley measuring device on a ground pulley support, unscrewing a gland on an oil remover (1), putting a logging cable into the well, screwing the gland, lifting 2 side connecting plates of a bounce prevention wheel (4) and a compression wheel (10), rotating for 90 degrees, putting the cable into the well, resetting the side connecting plates, and carrying out logging operation.
The oil remover (1) comprises a rubber packing, an opening gland and a packing sleeve, and plays a role in removing oil stains on a cable in logging operation and the like so as to ensure the cleanness and the measurement precision of the device.
The centralizing wheel (2) comprises a shaft pin, a bearing and a centralizing wheel, and plays a role in guiding a cable in logging operation.
The guide wheel (3) plays a role in guiding the cable in logging operation.
The anti-jumping wheel (4) plays a role in protecting a cable and preventing the cable from jumping a groove in logging operation.
The metering wheel (5) is used for measuring the running length of the cable.
The wireless signal transmitter (6) wirelessly transmits signals of the magnetic marker (7), the photoelectric encoder (8) and the tension meter (11) to the cloud center.
The magnetic marker (7) is used for measuring the length of the logging cable and transmitting the measured length to the wireless signal transmitter (6).
The photoelectric encoder (8) is used for measuring the revolution of the metering wheel (5), and converting the measured value into an electric signal and transmitting the electric signal to the wireless signal transmitter (6).
And the left clamping plate and the right clamping plate (9) are used for connecting and fixing the whole arc-shaped pulley measuring device.
The pressing wheel (10) is used for pressing the cable on the metering wheel (5), so that the measurement is more accurate.
The tension meter (11) is used for measuring the tension of the cable and transmitting the measured value to the wireless signal transmitter (6).
And the connecting lug (12) is used for connecting and fixing the whole arc pulley measuring device.
The minimum metering interval of the photoelectric encoder is 1/1280m, when the downhole instrument moves 1/1280m, the DEP _ A signal output end and the DEP _ B signal output end respectively generate a positive pulse signal, and the two positive pulse signals have a phase difference of 90 degrees. Meanwhile, when the moving directions of the logging cables are different, the phase difference between DEP _ A and DEP _ B is different. When the logging cable is lifted, the phase of DEP _ A leads the phase of DEP _ B by 90 degrees, namely DEP _ A-DEP _ B is equal to 90 degrees; when the wireline is run down, the phase of DEP _ a lags the phase of DEP _ B by 90 °, i.e., DEP _ a-DEP _ B is-90 °.
Because the photoelectric encoder belongs to strong current mechanical type test metering equipment, and the arc pulley controller belongs to a weak current precision measurement module, in order to prevent the weak current precision measurement module from being burnt out when the photoelectric encoder has short circuit and other power supply faults, the photoelectric encoder is required to carry out isolation processing on a photoelectric encoding pulse signal sent by the photoelectric encoder; on the other hand, because an optical code disc in the photoelectric encoder is very sensitive to the jitter of a logging cable, the disturbance mainly shows that a small-amplitude burr jitter phenomenon appears at the edge of an encoding pulse signal. Since the optocoupler has the characteristic of current drive, the optocoupler TLP521 is used for performing "pre-filtering" processing on the narrow pulses caused by jitter. Fig. 3 is a schematic circuit diagram of the photoelectric encoder of the present invention.
In fig. 3, an output signal DEP-A, DEP-B of the photoelectric encoder and a power supply ground of the system are connected to an input end of the optical coupler TLP521, the output signal is connected to a pull-up resistor, and the other end is connected to a ground of the arc-shaped pulley controller. The output signal is sent to the arcuate pulley controller after being driven by the line drive device 74HC 04.
The arc pulley controller comprises a signal conditioning circuit and a signal processing circuit. The photoelectric encoder is very sensitive to jitter interference caused by a photoelectric encoder shaft system, various random interferences also exist in a logging site, and output signals may have burrs, so that the interference needs to be isolated and subjected to jitter removal. Because the optocoupler device has the characteristic of current drive, transient narrow pulses cannot pass through. Therefore, the signal conditioning circuit adopts the optical coupler 6N137 to carry out primary de-jitter processing on random jitter narrow pulses and then reshape output signals. The pulse signal passes through a 54HC04 NOT gate, the output signal is subjected to photoelectric isolation and then sent to a Schmitt trigger CD40106 to shape the signal, the two paths of signal processing circuits are the same, and the designed signal conditioning circuit schematic diagram is shown in FIG. 4. The processed signal is fed to a signal processing circuit.
The signal processing circuit adopts an MSP430F2619 single chip microcomputer as a main chip, and the signal processing circuit calculates the depth metering signal so as to obtain the speed of the logging cable and the depth of the oil well.
The velocity of the wireline is calculated by the following equation:
when the data is n1 at the time t1 and n2 at the time t2, the velocity of the logging cable is calculated as follows:
V＝n2-/1280×1÷(t2-t1)＝n2-n1/1280×1÷nΔt
△ t is delay time;
the well depth is calculated by the following formula:
when the data is n1 at time t1 and n2 at time t2, the depth is calculated as follows:
H＝n2-n1/1280×1
when H is more than 0, the logging cable moves in the direction of going deep into the oil well; and when H is less than 0, the logging cable moves in the direction of withdrawing the oil well.
Fig. 5 is a schematic circuit diagram of a wireless signal transmission module according to the present invention. The wireless signal transmission module adopts an nRF905 wireless transceiver chip, the working voltage of the nRF905 wireless transceiver chip is 1.9V-3.6V, the nRF905 wireless transceiver chip works in 433/868/915MHz three ISM channels, and the maximum data transmission rate is 100 kb/s. The chip has very low energy consumption, when the chip is transmitted with the power of 10dBm, the working current is only 30mA, when the chip is received, the working current is only 12.5mA, and in various low-power working modes, the current is only 12.5 muA in a standby mode, so that the chip is convenient to work in the field.
The P5.1, P5.2 and P5.3 ports of the MSP430F2619 single chip microcomputer are configured into three-wire SPI function which can be directly connected with corresponding pins of the nRF905 by programming configuration through the SPI interface, the MSP430F2619 single chip microcomputer serves as a host, the nRF905 serves as a slave, and the circuit connection schematic diagram is shown in fig. 5.
Fig. 6 is a schematic circuit diagram of a display circuit in the wireless intelligent winch panel according to the present invention. The wireless intelligent winch panel adopts a liquid crystal module of LM240160GCW and is controlled by a single chip microcomputer MSP430 in the wireless intelligent winch panel. Because the bus of the single-chip MSP430 is not outward, people can not access the peripheral equipment in a direct mode but only in an indirect mode, the liquid crystal can display ASCII characters, Chinese characters and various curves, and the liquid crystal can be connected with the single-chip MSP430 to form a human-computer interface with strong function and simple structure. The port P7 of the MSP430 is used as a data bus for transmitting data or commands, and part of the ports P8 are used as a control bus for controlling the functions of the LM240160 GCW. GT23L32S4W is a high-capacity character library memory chip, which is communicated with P7.0-P7.2, P8.4 through SPI bus protocol, and Chinese characters or character codes to be displayed on the liquid crystal are directly read from the chip. The LCD backlight control circuit is composed of R50, R51 and Q4 and is realized by sending PWM signals by a singlechip MSP 430.
In order to verify the reliability of the system, an error correction coefficient measurement is carried out on a calibrated depth measurement system which passes through a standard well, and the theoretical circumference of a depth wheel of the calibrated depth measurement system is 609.6 mm. FIG. 7 is a graph of the error coefficient calculation results of the system of the present invention.
The average value L of the perimeter L is 609.5853mm, and the standard deviation sigma is 0.0336mm calculated according to the Bessel formula
Since the number of measurements is small, it can be considered that the error meets the t-distribution, and therefore, the romano-vsky criterion (t-test criterion) is used to determine whether a gross error exists. Because of the 2 nd measurement v2At the maximum, it can be suspected as a gross error, measured at 609.6356 mm. Having its circumference L removed
The average value L 'is 609.5798mm, and the standard deviation σ' is 0.028 mm.
When the significance is taken to be 0.01 and the number of measurements is 10, the check coefficient K (10, 0.01) of the t-distribution is 3.54, according to the romanofsky criterion:
|609.6356-L'|＝0.0558＜Kσ'＝0.09912
it can be considered that the 2 nd measurement result is not a gross error. In order to judge whether the measurement sequence has a system error, the residual error of the measurement sequence is plotted for observation, wherein the x axis is the measurement sequence number, and the y axis is the residual error. Since the residual error is generally positive and negative phases and has no significant change rule, no systematic error can be considered.
In conclusion, the measurement has no gross error and system error, and the correction coefficient C is within the range of-0.8 ‰ to +0.2 ‰, thus meeting the design precision requirement. The circumference of the metering wheel 5 measured using the present system is 609.5853mm, with a practical circumference of 609.6 mm. The correction value of the metering wheel can be determined to be-0.0147 mm, and the correction coefficient is-0.024 per thousand. The system of the present invention can be later corrected using this value during actual use.
