Description

Technical Field

[0001] This invention relates to the field of oil and gas drilling technology, specifically to a portable integrated gamma detector detection device and method. Background Technology

[0002] Conventional natural gamma-ray logging while drilling (VRLD) technology is widely used in the domestic market, and related technologies are mature. In recent years, with the exploration and development of unconventional oil and gas resources such as shale gas and tight oil and gas, azimuth gamma-ray logging while drilling (ARLD), especially near-bit azimuth Gamma-ray logging while drilling (NBLD), has become increasingly mature as a geological steering tool and an important technical means to improve the exploration and development of complex oil and gas reservoirs and unconventional oil and gas resources. For thin, pinch-out, or undulating reservoirs, azimuth Gamma-ray logging while drilling curves can promptly reflect the drill bit position and determine the top or bottom of the reservoir, which is beneficial for precise trajectory control. Azimuth Gamma-ray logging while drilling (AWD) tools use one or more integrated gamma detectors to collect formation gamma-ray intensity. The use of integrated gamma detectors is large, and the production, repair, and maintenance of the instruments all require testing of these integrated gamma detectors. Research shows that current testing equipment includes DC power supplies, counting devices, and computers, requiring a large amount of equipment, complex operation, and operators with certain professional knowledge, which is not conducive to large-scale production, manufacturing, and maintenance of the instruments.

[0006] Preferably, the output terminal of the power switch interface is connected to an AC-DC module. The output terminal of the AC-DC module is respectively connected to the input terminal of the power supply switch, the input terminal of the multi-channel digital current display tube group, the input terminal of the pulse counting acquisition and communication board, and the input terminal of the LCD display screen. The output terminal of the power supply switch is connected to the input terminal of the multi-channel digital current display tube group, and the output terminal of the multi-channel digital current display tube group is connected to the multi-channel USB power supply and pulse acquisition interface group. The output terminal of the multi-channel USB power supply and pulse acquisition interface group is connected to the input terminal of the pulse counting acquisition and communication board. The output terminal of the pulse counting acquisition and communication board is interconnected with the USB communication interface, and the output terminal of the pulse counting acquisition and communication board is connected to the input terminal of the LCD display screen.

[0007] Furthermore, the multi-channel digital current display tube group and the multi-channel USB power supply and pulse acquisition interface group are positioned one-to-one on the front panel. The multi-channel digital current display tube group includes a first digital current display tube, a second digital current display tube, a third digital current display tube, and a fourth digital current display tube. The multi-channel USB power supply and pulse acquisition interface group includes a first USB power supply and pulse acquisition interface, a second USB power supply and pulse acquisition interface, a third USB power supply and pulse acquisition interface, and a fourth USB power supply and pulse acquisition interface, which are used to connect to the integrated gamma detector respectively.

[0008] Preferably, the pulse counting acquisition and communication board includes an MCU, an isolation conversion module, an LCD display interface, a USB-RS485 driver circuit, and a storage module; the output of the isolation conversion module is connected to the MCU, and the output of the MCU is divided into three branches: the first branch is connected to the LCD display interface, and the LCD display interface is connected to the LCD display; the second branch is interconnected with the USB-RS485 driver circuit; and the third branch is interconnected with the storage module.

[0009] Furthermore, the pulse counting acquisition and communication board also includes a level conversion module, the input of which is connected to an AC-DC module, and the output of which is connected to an MCU.

[0010] Secondly, the present invention also provides a portable integrated gamma detector detection method, based on the aforementioned portable integrated gamma detector detection device, comprising the following process:

[0011] Connect the power switch interface to the mains power supply via the power cord and turn on the power to power the detection device. Connect multiple integrated gamma detectors to the pulse counting acquisition and communication board via test cables, USB power supply and acquisition interface group respectively. The pulse counting acquisition and communication board processes the acquired data and sends the results to the LCD screen in real time. Turn on the power supply switch and observe the count value and corresponding current value of the integrated gamma detector through the LCD screen and multi-channel digital current display group respectively. Record the displayed information and transmit it to the computer in real time through the USB communication interface to complete the integrated gamma detector detection.

[0012] Preferably, the pulse counting acquisition and communication board includes an MCU, an isolation conversion module, an LCD display interface, a USB-RS485 driver circuit, and a storage module. The working process of the pulse counting acquisition and communication board is as follows:

[0013] Upon power-on initialization, the timer interrupt duration is set according to user requirements, with the timer interrupt being the primary factor. Once the timer generates an interrupt, the MCU reads the pulse count and processes the pulse signal of the integrated gamma detector isolated by the isolation conversion module to obtain the multi-channel integrated gamma detector count rate. The count rate is then updated to the LCD display screen via the LCD display interface, sent to the USB communication interface via the USB-RS485 driver circuit, and stored in the storage module.

Once the timer generates an interrupt, the MCU (51) reads the pulse count and processes the pulse signal of the integrated gamma detector isolated by the isolation conversion module (52) to obtain the multi-channel integrated gamma detector count rate. The count rate is updated to the LCD display screen (7) via the LCD display interface (54), sent to the USB communication interface (17) via the USB-RS485 driver circuit (55), and stored in the storage module (56).

The portable integrated gamma detector detection method according to claim 7, characterized in that, The MCU (51) integrates the counting rate stability coefficient and high temperature counting rate deviation calculation, compares the calculation results with the user-set values, and displays the calculation results and comparison results on the LCD screen (7).

9. The portable integrated gamma detector detection method according to claim 8, characterized in that, The calculation process for the count rate stability coefficient is as follows: For a single-channel detector, 10 sets of detector data are continuously collected, and the maximum and minimum values ​​are taken respectively. The calculation formula is as follows: Where θ is the count rate stability coefficient; C MAX Set the maximum count value within a specified time period for the user; C MIN Set a minimum count value for the user within a specified time period.

10. The portable integrated gamma detector detection method according to claim 8, characterized in that, The calculation process for the high-temperature count rate deviation is as follows: Three sets of detector data were continuously collected under both normal and high temperature conditions, and the average value was calculated using the following formula: Where ξ is the high-temperature count rate deviation; C HIGH This represents the average of three sets of detector data within a user-defined timeframe under high-temperature conditions; C NORMAL This represents the average value of three sets of detector data within a user-defined time period under normal temperature conditions.
