Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0025] Considering the technical problems existing in the prior art, it is necessary to invent a solution for selective real-time transmission of downhole data, which includes a downhole multi-parameter measurement tool and a matching MWD transmission tool. The downhole multi-parameter measurement tool integrates multiple downhole engineering parameters on a short section, and can simultaneously measure 10 parameters such as drilling pressure, torque, temperature, pressure, rotation speed and triaxial vibration, allowing engineers to accurately judge downhole working conditions and predict complex downhole working conditions. The tool has a compact structure and is easy to operate on site. It can effectively improve drilling operation efficiency and reduce drilling costs and well control risks. Its main principle is to use downhole sensors to measure 10 engineering parameters such as drilling pressure, torque, temperature, pressure, rotation speed and triaxial vibration, and upload them to the ground through MWD after processing.

[0026] However, the transmission bandwidth of the current MWD transmission tools is very low, only 1-10b / s, which cannot meet the demand for real-time transmission of 10 parameters along with downhole data to the ground. In addition, different drilling parameters are required under different working conditions, and not all downhole data need to be uploaded at any time. Therefore, in the case of limited transmission bandwidth of existing MWD transmission tools, methods and devices for selective real-time transmission of downhole data under different working conditions are studied.

The following is a detailed introduction.

[0034] The embodiment of the present invention provides a method and device for selectively transmitting downhole data in real time, mainly relating to a method and device for selecting downhole engineering parameters to be transmitted according to ground control of operating conditions, and storing other parameters in a data storage module. Under different operating conditions, the ground control system sends an instruction of the measured data category and data volume to the downhole engineering parameter measurement tool through a downlink device. After receiving the instruction, the downhole engineering parameter measurement device uses the communication transmission management unit (module) in the downhole microprocessor (MCU) to control the communication circuit transmission switch, selectively switch the sensor communication channel, so as to obtain the required downhole data, and close unnecessary communication transmission channels. After the sensor that needs to transmit the signal obtains the required data, it sends it to the MCU module through the communication transmission module, transmits it to the MWD, and the MWD transmits the signal to the ground. After the sensor that does not need to transmit the signal obtains the required data, it sends it to the MCU module through the communication transmission module, and transfers it to the data storage module after processing, and reads and interprets it on the ground after the drilling tool leaves the well.

[0035] like Figure 1 As shown in FIG. 1 , the device mainly includes: a ground control and receiving module, a data transmission device, a data transmission device (MWD), and a downhole multi-parameter measurement tool. Figure 2 As shown, the downhole multi-parameter measurement tool includes a power supply system module, a microprocessor (MCU), a communication transmission management module, 10 parameter sensors such as drilling pressure, torque, temperature, pressure, speed and triaxial vibration, and a signal conditioning module, and a data storage module. The method of selectively transmitting downhole data in real time specifically includes:

[0036] ① Preset the command information codes required for different working conditions and operations, that is, the command information codes required for real-time transmission of downhole parameters. For example, the command code for the three parameters of downhole drilling pressure, torque and speed is 001, and the command code for the three parameters of downhole torque, temperature and pressure is 002, and so on.

[0037] ② Combine the drilling tools, connect and test the ground control and receiving module, data downlink device, data transmission device (MWD), and downhole multi-parameter measurement tool according to the diagram.

[0038] ③ After the drill bit is lowered to the bottom of the well and before the operation begins, the ground control and receiving module formulates the command information code of the required downhole parameters according to the current drilling operation conditions; for example, the command code for the three parameters of downhole drilling pressure, torque and speed is 001.

[0039] ④ The command information is encoded and sent to the data download device.

[0040] ⑤The data transmission device transmits the code to the downhole multi-parameter measurement tool.

[0041] ⑥ After receiving the code, the microprocessor (MCU) in the downhole multi-parameter measurement tool parses the instructions requiring three parameters: downhole drilling pressure, torque and speed.

[0042] ⑦The microprocessor (MCU) sends the instruction to the communication transmission management module, opens the communication transmission channels of drilling pressure, torque and speed, and transfers the communication transmission channels other than drilling pressure, torque and speed to the data storage module.

[0043] ⑧ The downhole multi-parameter measurement tool has three sensors that need to transmit data, namely, drilling pressure, torque and rotational speed. The downhole data is acquired, processed by its signal conditioning module, and then sent to the MCU module via the communication transmission module; the signal conditioning module in the embodiment of the present invention is essentially an isolation amplifier, and its main function is to amplify the signal and protect the front-end circuit. Since its own isolation voltage is very high, it greatly improves the performance of the measuring equipment without breakdown when used under harsh conditions.

[0044] ⑨The MCU module transmits data to the data transmission device (MWD, also known as the data upload device, such as Figure 3 The MWD transmits the signal to the ground control and receiving module, which receives and records the downhole data.

[0045] ⑩ Other sensors such as temperature that do not need to transmit data obtain downhole data; after being processed by its signal conditioning module, it is sent to the MCU module via the communication transmission module, and the MCU module transmits the data to the data storage module; that is, in one embodiment, Figure 2 As shown, the downhole multi-parameter measurement tool may further include: a data storage module; the method for selectively transmitting downhole data in real time also includes: sensors that do not need to transmit parameter data in real time store the acquired parameter data in the data storage module.

[0046] From the above, it can be seen that in one embodiment, if Figure 2 As shown, the downhole multi-parameter measurement tool may further include: a signal conditioning module;

[0047] The sensor that does not need to transmit parameter data in real time stores the acquired parameter data in the data storage module, including: the sensor that does not need to transmit parameter data in real time stores the acquired parameter data in the data storage module after being processed by the signal conditioning module;

[0048] The sensor corresponding to the opened communication transmission channel sends the required real-time transmission downhole parameter data to the MCU, including: the sensor corresponding to the opened communication transmission channel sends the required real-time transmission downhole parameter data to the MCU after being processed by the signal conditioning module.

[0049] When the working conditions change, repeat steps 3-10.

[0050] When the operation is completed and the tool is out of the well, the data storage module is connected to the ground control and receiving module to read and interpret the downhole data.

[0051] From the above, it can be seen that in one embodiment, if Figure 2 As shown, the downhole multi-parameter measurement tool may further include: a power supply system module; the method for selectively transmitting downhole data in real time also includes: the power supply system module provides power to each module of the downhole multi-parameter measurement tool.

[0052] In specific implementation, when the transmission bandwidth of existing MWD transmission tools and the capacity of downhole batteries are limited, the method for selectively transmitting downhole data in real time provided by the embodiment of the present invention can also further improve the battery life of downhole multi-parameter measurement tools.

[0053] In one embodiment, Figure 3 As shown, the installation position relationship between the downhole multi-parameter measurement tool and the drilling tool and other modules is: a data transmission device, a plurality of drill pipes connected in sequence, a drill collar, a data transmission device MWD, a downhole multi-parameter measurement tool, a drill collar and a drill bit.

[0054] During specific implementation, the downhole multi-parameter measurement tool integrates multiple downhole engineering parameters on a short section, and can simultaneously measure 10 parameters such as drilling pressure, torque, temperature, pressure, rotation speed and three-axis vibration, allowing engineering personnel to accurately judge the downhole working conditions and predict complex downhole working conditions. The tool has a compact structure and is easy to operate on site. It can effectively improve drilling operation efficiency and reduce drilling costs and well control risks.

[0055] The method for selectively transmitting downhole data in real time provided by the embodiment of the present invention reduces the impact of the limited transmission bandwidth of existing MWD transmission tools, improves data transmission efficiency and data transmission quality; it is suitable for selectively transmitting downhole data in real time under different working conditions, and can achieve required uploading and unnecessary storage, thereby ensuring effective measurement and transmission of downhole data.

[0056] At the same time, a data transmission device is added in the embodiment of the present invention, which can issue instructions at any time on the ground, and conveniently select and transmit downhole data on the ground. It is convenient and reliable, and also greatly improves the autonomy of downhole data transmission. Data transmission can be selected without starting drilling.

[0057] In addition, in the embodiment of the present invention, the data transmission device and the ground control module are the core. The data transmission device is a device that can receive instructions from the ground control module. After receiving the instructions, the data transmission device can generate drilling fluid pulses through a built-in switching device and send the pulse signal to the downhole data transmission device (MWD). After receiving the pulse signal, the MWD decodes and obtains the data instructions that need to be transmitted for selective transmission.
