Description

Technical Field

[0001] The present invention relates to the technical field of oil drilling equipment, in particular to the technical field of rotary steering equipment for drilling, and more specifically to a high-temperature probe for a rotary steering system. Background Art

[0002] Since the beginning of the development of the oil industry, oil drilling companies have had to face a series of difficult challenges. At present, most of the world's oil fields have entered the late stage of maturity, and production has begun to decline. Statistics from authoritative organizations show that most of the oil consumed in the world now is supported by oil fields discovered in previous explorations. Newly discovered oil is difficult to make up for the rapid decline in production of mature oil fields, but human demand for energy will continue to grow at least until 2030. How to make up for the huge gap in energy demand and supply is a difficult problem.

[0003] The effective measure to solve this problem is to improve the production efficiency and oil and gas utilization rate of the entire oil industry by developing new oil drilling, oil production and refining technologies, so that oil and gas resources can meet the growing needs of mankind. The progress of science and technology will become the most obvious feature to promote the advancement of the world's oil industry in the 21st century. New technologies have been invested in the oil industry to greatly improve the oil recovery rate of existing oil fields and the exploration and development efficiency of new oil fields, such as three-dimensional dynamic visual observation of exploration and development, real-time geological and seismic information transmission while drilling, continuous tubing drilling, underwater multiphase pumping and metering systems, drilling and completion of multi-branch wells, and ultra-long extension wells.

[0004] The advancement of science and technology has enabled people to find oil and gas in more areas, such as areas with complex geological structures: seabed, desert, etc. For the development of complex bottom oil and gas, such as shale gas, coal gas layer, etc., due to their complex geology, rotary steerable system drilling technology is needed in large displacement horizontal wells, complex ultra-deep directional wells, etc. The rotary steerable system technology can better adapt to the exploitation of oil and gas under complex geological conditions and can increase the production of oil and gas. While the rotary steerable system is adapted to the exploitation of oil and gas in complex geology, it is cheaper than traditional drilling technology and is simpler to operate than the transmission drilling system. Compared with traditional drilling technology, the friction resistance and torque resistance on the drill string of rotary steerable drilling technology are smaller, so that the drill string of rotary steerable drilling technology can effectively improve work efficiency and have a longer service life. During the drilling process, the condition in the wellbore can be viewed more clearly, and the actual condition can be understood at any time under complex geological conditions, which can prevent accidents that may occur during the drilling process in time.

[0005] Therefore, developing a rotary steerable system with independent intellectual property rights that can replace foreign products has great and far-reaching significance. Especially as the well depth increases, the underground working temperature increases, and the development of a high-temperature rotary steerable system can better perform deeper wells.

[0006] The probe is an important part of the rotary steering system. The rotary steering system uses the posture measured by the probe to control the direction of the system, including the well inclination, azimuth and tool face control of the rotary steering system. During the communication process, the posture is sent to the hollow unit of the rotary steering system through the single bus conversion part. Therefore, it is of great and far-reaching significance to develop a high-temperature probe suitable for the rotary steering system so that it can better perform drilling operations at deeper wells.

The two ends of the pressure-resistant tube are respectively connected to the left suspension propeller and the right suspension propeller. The battery pressure-resistant tube is assembled at the other end of the right suspension propeller. The circuit board rack is connected to the right suspension propeller through a sealing screw and is located in the pressure-resistant tube; a high-temperature battery is arranged in the battery pressure-resistant tube, and the high-temperature battery is connected to the right suspension propeller through a sealing screw; an accelerometer, a temperature sensor, a flux gate, a filter circuit, an acquisition and transmission circuit, a single bus conversion circuit and a power control circuit are arranged on the circuit board rack; the electronic components assembled on the circuit board rack are all high-temperature resistant electronic components.

[0019] Compared with the prior art, the beneficial technical effects brought by the present invention are as follows:

[0020] 1. Compared with the prior art, the circuit board rack is assembled by a pressure-resistant tube, and the pressure-resistant tube plays a protective role on the circuit board rack and the electrical components on the circuit board rack. The pressure-resistant tube is set between the left suspension paddle and the right suspension paddle, and the circuit board rack and the right suspension rack are fixed by sealing screws, so that the electrical components on the circuit board rack can monitor the posture of the probe tube and ensure the accuracy of the monitored data.

[0021] 2. In the present invention, the electrical components, circuit boards and batteries that constitute each circuit on the circuit board rack are all made of high-temperature resistant electronic components. The selected electronic components can withstand a high temperature of 175 degrees, avoiding the influence of the high-temperature environment underground on the electronic components on the circuit board rack, so that the probe can be suitable for the high-temperature environment underground, and can better carry out drilling operations in deeper wells.

[0022] 3. In the present invention, the filtering circuit, the acquisition and transmission circuit, the single bus conversion circuit and the power control circuit can play a role in reducing power consumption, ensuring that the accelerometer, the flux gate and the temperature sensor can work in a high temperature environment of 175 degrees.

The single chip microcomputer in the acquisition and transmission circuit can determine whether it is powered by the system or the battery. When the battery is powered, the data collected by the probe tube does not need to be transmitted to the central control unit of the rotary steering system through the single bus conversion circuit, but is temporarily stored in the memory of the acquisition and transmission circuit. After the system resumes power supply, the data collected during the system power outage is transmitted to the central control unit of the rotary steering system through the single bus conversion circuit and the single-core connector.

[0023] 4. In the present invention, the acquisition and transmission circuit includes an acquisition module, a single-chip microcomputer and a memory, wherein the single-chip microcomputer receives the electrical signal converted by the acquisition module, and calculates the current well inclination angle, tool face angle, azimuth angle and temperature of the rotary steering system according to the conversion coefficient of the corresponding electrical signal. The present invention does not transmit the signal to the rotary steering central control system, but processes the data downhole to calculate the well inclination angle, tool face angle, azimuth angle and temperature data, and transmits the processed data to the rotary steering central control unit, which does not require the central control unit to perform data processing, which is beneficial to the processing and recording of the data detected by each sensor after the system is powered off.
