Description

Technical Field

[0001] The invention relates to a downhole instrument integrated power supply system, belonging to the technical field of oil drilling. Background Art

[0002] With the progress of oil and gas development, the easy-to-develop oil and gas resources have been basically consumed. Now the difficulty of oil and gas development is increasing, and higher requirements are placed on oil drilling instruments. In particular, drilling instruments face more complex situations and their working time underground is constantly extended, which places higher requirements on the power supply of the instruments. The existing power supply technology can meet the current needs, but it needs to be improved for long-term development. A comprehensive and universal power supply solution is urgently needed. Summary of the invention

[0003] In view of the above-mentioned technical problems existing in the prior art, the present invention proposes an integrated power supply system for downhole instruments, which makes up for the defects of the current downhole power supply devices and provides a comprehensive and stable power supply system.

[0004] The present invention proposes a downhole instrument integrated power supply system, comprising:

[0005] A downhole power storage device, which can be charged and discharged and provide power for downhole instruments;

[0006] A downhole power generation device, wherein the downhole power generation device is configured to generate electricity through the circulating drilling fluid, thereby charging the downhole power storage device;

[0007] A ground energy supply system, wherein the ground functional system transmits radio frequency signals to the underground, and the underground power storage device is connected to a wireless radio frequency receiving module;

[0008] Among them, when the pump is turned on, the downhole power storage device is charged by the downhole power generation device, and when the pump is turned off, the ground power supply system transmits the radio frequency signal to the downhole, which is received and converted into electrical energy by the wireless radio frequency receiving module to charge the downhole power storage device.

[0009] A further improvement of the present invention is that the three power supply modes of battery, mud engine and RF signal wireless power supply are used for comprehensive power supply, wherein the battery is connected to the downhole instrument to provide a standard and stable voltage output for the instrument. The mud engine and the RF signal provide a comprehensive input for the power supply module.

[0010] A further improvement of the present invention is that the charging end of the downhole energy storage device is connected to an electric energy processing module, and the electric energy processing module is respectively connected to the downhole power generation device and the wireless radio frequency receiving module.

[0011] When the mud generator is turned on, the drilling fluid begins to circulate, driving the generator blades to rotate and provide power to the instrument. However, the drilling speed of the generator is related to the mud circulation speed. In the on-site construction environment, the drilling fluid circulation speed is closely related to the working conditions and is constantly changing, and cannot circulate smoothly for a long time.

[0012] The wireless receiving module will also be affected by the working conditions of drilling construction when receiving radio frequency signals, and the output power is also unstable. Therefore, the power processing module is used to process the power output by the downhole power generation device and the wireless radio frequency receiving module to obtain stable and safe power.

[0013] A further improvement of the present invention is that the power processing module comprises a conditioning circuit, and the conditioning circuit adjusts the phase and frequency of input signals with different phases and frequencies to be consistent.

[0014] A further improvement of the present invention is that the conditioning circuit is connected to a superposition circuit, and when the input phase and frequency are substantially consistent, the superposition circuit superposes the phases of multiple signals to merge them into one AC signal; and then passes the unified input signal through a rectifier.

[0015] A further improvement of the present invention is that the superposition circuit is connected to a rectifier to rectify and filter the AC signal to form a DC signal.

[0016] A further improvement of the present invention is that the rectifier is connected to a power management chip, and the power management chip supplies the DC signal to the battery stably.

[0017] A further improvement of the present invention is that the ground functional system includes a radio frequency signal transmitting device arranged on the ground and a plurality of relay units arranged underground;

[0018] The radio frequency signal transmitting device transmits radio frequency signals in the drilling direction of the drilling rig, and transmits them to the wireless radio frequency receiving module underground through several relay units.

[0019] Among them, the ground energy supply system and relay unit are set up to transmit radio frequency signals to transmit energy, charge the underground power storage device in the well, and ensure sufficient power supply. This solves the problem that the difficulty of oil and gas development is increasing, the amount of data to be processed is increasing, and the existing underground generators and batteries cannot meet the current power supply needs.

[0020] A further improvement of the present invention is that the wireless radio frequency receiving module includes a cylindrical main body, and a plurality of radio frequency signal receivers are evenly arranged in the circumferential direction of the main body; a plurality of mud channels are radially arranged in the main body, and the mud channel is arranged between two adjacent radio frequency signal receivers.

[0021] The number of the wireless RF receiving modules is preferably three, which are evenly arranged on the main body at 120°. When receiving RF signals, the wireless receiving modules will also be affected by the working conditions of the drilling construction, and the posture of the drill collar underground will also affect the signal reception.

[0022] A further improvement of the present invention is that the downhole power generation device is a mud generator.

[0023] A further improvement of the present invention is that the conditioning circuit includes an amplitude modulation circuit, a phase modulation circuit and a frequency modulation circuit.

[0024] The amplitude modulation circuit, the phase modulation circuit and the frequency modulation circuit are connected in series, and the order can be adjusted. During the operation of the conditioning circuit, the amplitude modulation circuit, the phase modulation circuit and the frequency modulation circuit are controlled to be in a working or non-working state according to the electric energy signal to be conditioned.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] The downhole instrument integrated power supply system described in the present invention addresses the problem of downhole instrument power supply. In the prior art, the circuit is powered by a mud generator when the pump is turned on, and is powered by a battery in the drill collar when the pump is turned off. The power generation of the mud generator depends on the circulation speed of the drilling fluid, and the power supply is unstable. Battery power supply occupies a large amount of space and has a limited power generation time. The present invention proposes a new power supply method, which increases the reliability of instrument operation. In addition, the invention has little impact on existing designs, will not affect the mud generator and battery power supply methods, and only slight modifications are required to make existing instruments compatible with this technology.

[0027] The downhole instrument integrated power supply system of the present invention has a reliable power management solution, can regulate charging and discharging, and provide stable and effective power supply to the instrument while ensuring safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the technical solutions and advantages of the present invention more clearly understood, the exemplary embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than an exhaustive list of all the embodiments. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0040] With the progress of oil and gas development, the easy-to-develop oil and gas resources have been basically consumed. Now the difficulty of oil and gas development is increasing, and higher requirements are placed on oil drilling instruments. In particular, drilling instruments face more complex situations and their working time underground is constantly extended, which places higher requirements on the power supply of the instruments. The existing power supply technology can meet the current needs, but it needs to be improved for long-term development. A comprehensive and universal power supply solution is urgently needed.

[0041] Figure 1 A downhole instrument integrated power supply system according to the present invention is schematically shown, comprising:

[0042] A downhole power storage device 4, which can be charged and discharged and provide power for downhole instruments;

[0043] A downhole power generation device 5, wherein the downhole power generation device 5 is configured to generate electricity through the circulating drilling fluid, thereby charging the downhole power storage device 4;

[0044] The ground energy supply system, the ground functional system 2 transmits radio frequency signals to the underground, and the underground power storage device 4 is connected to a wireless radio frequency receiving module 6;

[0045] Among them, when the pump is turned on, the downhole power storage device 4 is charged by the downhole power generation device 5, and when the pump is turned off, the ground power supply system transmits the radio frequency signal to the underground, which is received and converted into electrical energy by the wireless radio frequency receiving module 6 to charge the downhole power storage device 4.

[0046] According to the downhole instrument integrated power supply system described in this embodiment, three power supply modes, namely, battery, mud engine, and RF radio frequency signal wireless power supply, are used for integrated power supply, wherein the battery is connected to the downhole instrument to provide a standard and stable voltage output for the instrument. The mud engine and the radio frequency signal provide integrated input for the power supply module.

[0047] In one embodiment, Figure 2 As shown, the charging end of the downhole energy storage device is connected to an electric energy processing module 7, and the electric energy processing module 7 is respectively connected to the downhole power generation device 5 and the wireless radio frequency receiving module 6.

[0048] When the mud generator is turned on, the drilling fluid begins to circulate, driving the generator blades to rotate and provide power to the instrument. However, the drilling speed of the generator is related to the mud circulation speed. In the on-site construction environment, the drilling fluid circulation speed is closely related to the working conditions and is constantly changing, and cannot circulate smoothly for a long time.

[0049] The wireless receiving module will also be affected by the working conditions of drilling construction when receiving radio frequency signals, and the power output by it is also unstable. Therefore, the power processing module 7 processes the power output by the downhole power generation device 5 and the wireless radio frequency receiving module 6 to obtain stable and safe power.

[0050] In a preferred embodiment, Figure 3 As shown, the power processing module 7 includes a conditioning circuit 8, and the conditioning circuit 8 adjusts the phase and frequency of input signals with different phases and frequencies to be consistent.

[0051] Preferably, the conditioning circuit 8 is connected to the superposition circuit 9. When the input phase and frequency are substantially consistent, the superposition circuit 9 superimposes the phases of the multiple signals to merge them into one AC signal; and then passes the unified input signal through the rectifier 10.

[0052] Preferably, the superposition circuit 9 is connected to a rectifier 10 to rectify and filter the AC signal to form a DC signal.

[0053] Preferably, the rectifier 10 is connected to a power management chip 11, and the power management chip 11 supplies a DC signal to the battery stably.

[0054] The processed DC signal will change constantly because the working conditions will have a certain impact on the received signal. Therefore, it is necessary to pass through a power management chip 11 to smoothly supply the input signal to the battery. The battery has different charging modes and supplies power to the battery at a preset power. The battery then supplies the instrument with a stable output.

[0055] In one embodiment, the ground functional system 2 includes a radio frequency signal transmitting device arranged on the ground and a plurality of relay units 3 arranged underground;

[0056] The radio frequency signal transmitting device transmits radio frequency signals in the drilling direction of the drilling rig, and transmits the radio frequency signals to the wireless radio frequency receiving module 6 underground through a plurality of relay units 3 .

[0057] According to the downhole instrument integrated power supply system described in this embodiment, the ground power supply system and the relay unit 3 are set to transmit radio frequency signals to transmit energy, and the downhole power storage device 4 is charged to ensure sufficient power supply. The problem that the difficulty of oil and gas development is increasing, the amount of data to be processed is increasing, and the downhole generators and batteries in the existing technology cannot meet the current power supply needs is solved.

[0058] In one embodiment, the wireless RF receiving module 6 includes a cylindrical main body 15 , and a plurality of RF signal receivers 16 are evenly arranged in the circumferential direction of the main body 15 ; a plurality of mud channels 17 are radially arranged in the main body 15 , and the mud channel 17 is arranged between two adjacent RF signal receivers 16 .

[0059] Preferably, there are three wireless RF receiving modules 6, which are evenly arranged at 120° on the main body 15. When receiving RF signals, the wireless receiving module will also be affected by the working conditions of the drilling construction, and the posture of the drill collar underground will also have an impact on the signal reception. In order to better receive the signal sent from the ground, the wireless receiving module has three receivers, each installed on the drill collar at 120°. This can ensure a better reception effect, and at the same time, in conjunction with the power processing module 7, it can process unstable power into stable and safe power to charge the underground power storage device 4.

[0060] In one embodiment, the downhole power generation device 5 is a mud generator.

[0061] In one embodiment, the conditioning circuit includes an amplitude modulation circuit, a phase modulation circuit and a frequency modulation circuit. In this embodiment, the amplitude modulation circuit, the phase modulation circuit and the frequency modulation circuit are connected in series, and the order can be adjusted. During the operation of the conditioning circuit, the amplitude modulation circuit, the phase modulation circuit and the frequency modulation circuit are controlled to be in a working or non-working state according to the electric energy signal to be conditioned. For example, when only the phase needs to be adjusted, the amplitude modulation circuit and the frequency modulation circuit are in a non-working state, and the phase modulation circuit is in a working state; when only the frequency needs to be adjusted, the amplitude modulation circuit and the phase modulation circuit are in a non-working state, and the frequency modulation circuit is in a working state; when the phase and frequency need to be adjusted, the amplitude modulation circuit is in a non-working state, and the frequency modulation circuit and the phase modulation circuit are in a working state; when no adjustment is required, all three groups of circuits are in a non-working state, and so on.

[0062] Preferably, the amplitude modulation circuit is as follows Figure 4 As shown, the amplitude modulation circuit adopts a variable gain amplifier circuit, including an amplifier module and a gain control module, and the amplifier module and the gain control module are connected in parallel.

[0063] The phase modulation circuit is as follows Figure 5 As shown, in this embodiment, the phase modulation circuit adopts a three-stage single-loop varactor diode phase modulation circuit. Each loop has a varactor diode to achieve phase modulation, and the capacitance changes of the three varactor diodes are controlled by the same modulation signal. In order to ensure that the three loops produce equal phase shifts, the Q value of each loop can be adjusted by a variable resistor. Small capacitors are used as coupling capacitors between stages. Because of their weak coupling, it can be considered that the mutual influence between stages is small, and the total phase shift is the sum of the three-stage phase shifts.

[0064] The frequency modulation circuit is as follows Figure 6 As shown, in this embodiment, the baseband signal of the frequency modulation circuit inputs into the RC coupling circuit and enters the modulation loop through the voltage follower. U1 is a voltage controlled oscillator (VCO) to provide frequency offset. The frequency offset is determined by the control voltage VCC. The control voltage is usually proportional to the amplitude of the baseband signal and then converted into frequency change. The modulated signal enters the bandpass filter to limit the output signal.

[0065] In one embodiment, the downhole instrument integrated power supply system further includes a downhole equipment cooling system. The downhole equipment cooling system can be installed on the drill collar where the downhole power storage device 4 is located, or can be set on other downhole devices. The downhole equipment cooling system includes:

[0066] The semiconductor heat sink 12 includes a heat absorbing end 14 and a heat dissipating end 14, wherein the heat absorbing end 14 is connected to the heating element through thermal conductive silicone grease, and the heat dissipating end 14 is connected to the inner wall of the drill collar;

[0067] The heat of the heating element is transferred to the heat absorbing end 14 of the semiconductor radiator through the thermal grease, and the semiconductor radiator transfers the heat to the heat dissipating end 14 and to the outer wall of the mud and is taken away by the mud.

[0068] In the downhole instrument integrated power supply system according to this embodiment, a semiconductor heat sink 12 is used for heat dissipation, and the heat sink is attached to the surface of the heating element through a heat dissipation medium such as silicone grease. When the component generates heat, the heat is transferred from the hot end 14 to the cold end 13 through the principle of the semiconductor heat sink 12, and the heat is transferred to the outside of the drill collar through the heat pipe, and the extra heat is taken away through the circulation of mud. The present invention can support the normal operation of the downhole instrument 1 and avoid affecting its working performance due to the high temperature of the heating element.

[0069] In one embodiment, a control module is provided on the semiconductor heat sink 12, and the control module controls the opening or closing of the semiconductor heat sink 12 according to the temperature of the heating element. The control module can be integrated with the controller or provided separately for heat dissipation.

[0070] In one embodiment, the control module is connected to a power supply and a temperature sensor in a downhole instrument, determines whether heat dissipation is required based on a temperature signal from the temperature sensor, and connects the semiconductor heat sink 12 via an I / O port push-pull output circuit of the main control chip.

[0071] This embodiment uses a semiconductor heat sink 12 for heat dissipation. The heat sink is attached to the surface of the heating element through a heat dissipation medium such as silicone grease. When the component generates heat, the heat is transferred from the hot end 14 to the cold end 13 through the principle of the semiconductor heat sink 12, and the heat is transferred to the outside of the drill collar through the heat pipe, and the extra heat is taken away by the circulation of mud.

[0072] The heating element is directly connected to the semiconductor heat sink 12 through a heat-conducting medium such as silicone grease. The semiconductor heat sink 12 is powered by the downhole instrument power supply system. The temperature sensor in the downhole instrument is used to determine whether heat dissipation is needed. An I / O port of the main control chip can reuse pins and a transistor to determine whether the heat dissipation function needs to be turned on. Heat dissipation is only turned on when the heat generation is large to save electricity.

[0073] When the semiconductor heat sink 12 starts working, the heat is transferred from the heating end 14 to the cold end 13. The cold end 13 receives the heat and is connected to the inner wall of the drill collar. The heat of the component is transferred to the outer wall of the drill collar through the metal structure of the drill collar, and then the heat is taken away by the mud circulation.

[0074] The downhole instrument integrated power supply system of the present invention aims at the problem of downhole instrument power supply. In the prior art, the circuit is powered by a mud generator when the pump is turned on, and the battery in the drill collar is powered when the pump is turned off. The power generation of the mud generator depends on the circulation speed of the drilling fluid, and the power supply is unstable. The battery power supply occupies a lot of space and the power generation time is limited.

[0075] The downhole instrument integrated power supply system of the present invention proposes a new power supply method, solves the problems of the prior art, and increases the reliability of instrument operation. Moreover, the invention has little impact on the existing design, does not affect the mud generator and battery power supply method, and only requires slight modification to make the existing instrument compatible with this technology.

[0076] The downhole instrument integrated power supply system of the present invention adopts semiconductor heat sink for heat dissipation, and provides that the heat sink is attached to the surface of the heating element through a heat dissipation medium such as silicone grease. When the component generates heat, the heat is transferred from the hot end to the cold end through the principle of the semiconductor heat sink, and the heat is transferred to the outside of the drill collar through the heat pipe, and the extra heat is taken away by the circulation of mud.

[0077] The present invention can provide support for the normal operation of downhole instruments and avoid the influence of the working performance of the heating element due to the high temperature.
