Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas field drilling, and in particular to an intelligent starting method and system for oil and gas field drilling tool functions. Background Art

[0002] Before drilling tools are lowered into the well and begin operations, they must undergo certain activation procedures, such as depassivating the tool's lithium battery, connecting and energizing the battery, or initiating data acquisition. These operations are typically performed in a maintenance service workshop before the tool is delivered to the drilling site, based on the scheduled start-up time.

[0003] However, drilling operations can experience delays ranging from hours to weeks, causing drilling tools to miss their scheduled start-up times and necessitating tool reconfiguration to enable intelligent activation of certain functions. Typically, tool reconfiguration requires disassembly and reassembly. If these operations are performed on a drilling platform, specialized tool kits must be installed at the drilling site, and trained operators must reactivate the tools. Alternatively, the tools must be transported back to a maintenance workshop. These operations inevitably require additional expenses, resources, and time, increasing tool operating costs. Furthermore, these operations are considered infeasible on offshore drilling platforms. Summary of the Invention

[0004] An embodiment of the present invention provides an intelligent startup method and system for oil and gas field drilling tool functions to solve the problems raised in the above background technology, such as the reconfiguration of tool disassembly and assembly tool kit installation, the configuration of professional operators, the automation of drilling operations and low efficiency, which increase tool operating costs.

[0005] In one aspect, an embodiment of the present invention provides a method for intelligently starting a function of an oil and gas field drilling tool, comprising:

[0006] On-site operators place the drilling tools according to the preset posture;

[0007] The sensor measures and collects the current posture signal of the drilling tool;

[0008] The processor calculates the current posture signal to obtain the current posture sequence of the drilling tool;

[0009] The processor compares the current posture sequence of the drilling tool with a preset posture sequence, and when determining that the current posture sequence of the drilling tool is consistent with the preset posture sequence, the processor starts the function of the drilling tool.

[0010] On the other hand, an embodiment of the present invention provides an intelligent activation system for oil and gas field drilling tool functions, comprising:

[0011] A measuring sensor is installed on the drilling tool and is used to measure and collect the current posture signal of the drilling tool;

[0012] The main control microprocessor is used to solve the current posture signal, obtain the current posture sequence of the drilling tool, and compare the current posture sequence with the preset posture sequence. When the posture sequence is consistent with the preset posture sequence, the function of the drilling tool is activated;

[0013] The data storage module is used to store the current posture sequence of the drilling tool, relevant information and data of the tool startup, and read the data after the tool is recovered.

[0014] The intelligent activation method and system of an oil and gas field drilling tool function in the present invention has the following advantages:

[0015] During the drilling operation, it can reduce the configuration of drilling tool disassembly and installation packages and the configuration of professional operators, improve the intelligence of oil and gas field drilling tools, significantly reduce the difficulty of on-site drilling operations, and ensure the economic benefits of drilling operations.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Figure 1This is a flow chart of a method for intelligently activating the functions of an oil and gas field drilling tool provided by an embodiment of the present invention. The embodiment of the present invention provides a method for intelligently activating the functions of an oil and gas field drilling tool, comprising:

[0022] S100: The on-site operator places the drilling tool according to a preset posture;

[0023] S110, the sensor measures and collects the current posture signal of the drilling tool;

[0024] S120, the processor calculates the current posture signal to obtain the current posture sequence of the drilling tool;

[0025] S130: The processor compares the current posture sequence of the drilling tool with a preset posture sequence. When it is determined that the current posture sequence of the drilling tool is consistent with the preset posture sequence, the processor starts the function of the drilling tool.

[0026] For example, conventional battery-powered downhole dynamics acquisition tools can measure and store data such as the drilling tool's three-axis acceleration, rotational speed, and temperature. However, battery power and memory capacity are limited. If the drilling tool is not drilling, it will collect useless data and information. Furthermore, if the downhole dynamics acquisition tool is kept in operation for extended periods, the battery will be depleted. Therefore, effective management of battery power and memory capacity is essential to ensure the proper operation of the downhole dynamics acquisition tool.

[0027] Downhole dynamics acquisition tools have a real-time clock that keeps track of time. When they begin collecting and recording data, they must be programmed with an estimated time, which corresponds to the estimated start time for data collection. After programming, the operator assembles the downhole dynamics acquisition tool into the drilling tool and transports it to the drilling site. However, unforeseen circumstances can cause drilling operations to be delayed by hours or even weeks. The downhole dynamics acquisition tool, already programmed to wake up at the operator's pre-set data collection start time, will begin recording sensor data while the drilling tool is not drilling at the wellsite. To prevent this, the operator must disassemble the downhole dynamics acquisition tool, reprogram the data collection start time, and then assemble it into the drilling tool. This disassembly and assembly process requires specialized tools installed at the drilling site and is performed on-site by trained operators. This may even require transporting the tool back to a maintenance shop for this operation, which requires additional personnel, expense, and time, significantly impacting drilling efficiency and further increasing production costs.

[0028] After adopting the method of the present invention, at the drilling site, the operator first places the drilling tool to a preset posture (such as horizontal-vertical-horizontal) according to the drilling needs, then installs a measuring sensor on the drilling tool, uses the measuring sensor to collect the drilling tool's posture signal, and uses the signal processing circuit to filter and amplify the noise signal. The main control processor then solves the posture signal to obtain the real-time posture sequence of the drilling tool. When the main control processor determines that the real-time posture sequence of the drilling tool is consistent with the preset posture sequence, it activates certain functions of the drilling tool or performs pre-programmed operations. The above process avoids the assembly and disassembly of the drilling dynamics tool at the drilling site, saves key resources and time, improves the production efficiency of the drilling operation, and saves production costs.

[0029] After the measurement sensor is installed on the drilling tool, the three-axis installation direction of the sensor, such as Figure 2 As shown in (a) of FIG. Schematic diagram of the top view rotation direction of the oil and gas field drilling tool, as shown in FIG. Figure 2 As shown in (b) in .

[0030] In an embodiment of the present invention, the functions of the drilling tool initiated by the main control processor are not limited to performing certain control operations in the tool, waking up the system, starting fast data acquisition, starting power supply for functional circuits, starting battery depassivation operations, adjusting tool parameters, etc.

[0031] In a possible embodiment, after determining that the current posture sequence of the drilling tool is consistent with a preset posture sequence, the processor also determines whether the maintenance time of each posture of the drilling tool reaches a predetermined maintenance time. When the maintenance time of the current posture sequence reaches the predetermined maintenance time, the function of the drilling tool is started.

[0032] For example, a maintenance time requirement can be set for each posture of the drilling tool. For example, when drilling operations are to begin, there are n posture positions placed at the drilling site according to pre-set requirements. The time required to maintain each posture position is D1, D2...Dn, and the preset maintenance time for each posture position is T1, T2...Tn. Only when the maintenance time D1 of each posture placed on site of the drilling tool is greater than or equal to the preset maintenance time T1 requirement for each posture, and the posture maintenance time D2 is greater than or equal to the preset maintenance time T2 for each posture... The posture maintenance time Dn is greater than or equal to the preset maintenance time Tn requirement for each posture, will the main control processor determine that the current posture sequence of the drilling tool is consistent with the set posture sequence and start the function of the drilling tool. If the maintenance time of any of the postures does not meet the corresponding maintenance time requirement, the measurement sensor continues to collect the posture signal of the drilling tool.

[0033] In a possible embodiment, the attitude data includes: three-axis gravity acceleration, well inclination angle, tool face angle, and rotation speed.

[0034] For example, drilling tool attitude signals, such as triaxial gravity acceleration and rotational speed, are collected by measurement sensors and resolved by the main control processor to obtain the drilling tool attitude sequence. The main control processor also calculates the well inclination and tool face angle based on triaxial gravity acceleration.

[0035] The three-axis gravitational acceleration is G X , G Y , G Z , the calculated well inclination angle θ and tool face angle α are:

[0036]

[0037]

[0038] The embodiment of the present invention also provides an intelligent starting system for oil and gas field drilling tool functions, such as Figure 3 As shown, the system includes:

[0039] A measuring sensor is installed on the drilling tool and is used to measure and collect the current posture signal of the drilling tool;

[0040] The main control microprocessor is used to solve the current posture signal to obtain the current posture sequence of the drilling tool, and compare the current posture sequence with the preset posture sequence. When the current posture sequence is consistent with the preset posture sequence, the function of the drilling tool is activated;

[0041] The data storage module is used to store the current posture sequence of the drilling tool, relevant information and data of the tool startup, and read the data after the tool is recovered.

[0042] For example, the measurement sensor may be a three-axis gravity acceleration sensor or three independent gravity acceleration sensors.

[0043] In addition to the measuring sensor and main control processor, the system also includes a power supply circuit, a clock circuit, a signal conditioning circuit, and a main control processor circuit. The power supply circuit is used to power the measuring sensor, main control microprocessor, and data storage module, and the clock circuit is used to provide the clock frequency. The signal conditioning circuit is located between the measuring sensor and the main control processor, while the memory is connected to the main control processor. The measuring sensor is installed in the drilling dynamics tool to measure the current attitude of the drilling tool. The main control processor circuit converts the current drilling tool attitude signal from an analog quantity into an electrical signal that is easy to process and solve, and transmits it to the signal conditioning circuit. The signal conditioning circuit is mainly used to filter and amplify the attitude signal output by the measuring sensor, so that the main control processor can accurately solve the current tool attitude signal and thus calculate the tool's well inclination angle and tool face angle.

[0044] The main control processor and memory may adopt a hardware circuit with a main control microprocessor as the core. The main control microprocessor includes but is not limited to a DSP (Digital Signal Processing) processor, an ARM (Advanced RISC Machine) processor, a PLC (Programmable Logic Controller) processor, or an FPGA (Field Programmable Gate Array) processor.

[0045] The status of downhole drilling tools during drilling operations mainly includes: loading the drilling tools into the transportation system, assembling the drilling tools into the downhole tool assembly (BHA) system, pumping drilling fluid by the drilling tools, rotating the drilling tools, a certain degree of impact and vibration of the drilling tools, a certain degree of stick-slip of the drilling tools, and changes in the direction and posture of the drilling tools.

[0046] In an embodiment of the present invention, the measurement sensor includes: a three-axis acceleration sensor, a three-axis magnetometer, a gyroscope sensor, and a flow meter.

[0047] In an embodiment of the present invention, a three-axis acceleration sensor uses a multi-sensor combination to measure the earth's gravity field and perform attitude calculation.

[0048] For example, due to the vibration and noise interference during drilling operations, it is difficult to design and solve the gravity field using only acceleration sensors. Therefore, the present invention uses a multi-sensor combination device to perform attitude measurement.

[0049] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0050] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
