Description

Technical Field

[0001] The present invention relates to the technical field of automatic control of petroleum geological exploration, and in particular to a self-adaptive temperature regulation control device and a temperature regulation control method for a top drive gear box. Background Art

[0002] Overheating of the top drive gearbox can lead to gear failure and alarm shutdown of the top drive, seriously reducing the life of the top drive gearbox and on-site operation efficiency. The function of the top drive cooling device is to ensure that the top drive can operate normally and reliably at the most suitable temperature under any load. At present, the cooling of the top drive gearbox generally adopts forced air cooling. The lubricating oil pump is used to circulate the lubricating oil inside the top drive gearbox to the fan for forced cooling. The cooled lubricating oil then flows into the top drive gearbox. The circulating lubricating oil reduces the temperature of the top drive gearbox. In order to avoid temperature rise failures, it is often selected based on experience to run a high-power fan at full power.

[0003] However, during the entire drilling cycle, the load conditions of the top drive change continuously with the well depth, and the output torque and power of the top drive are also different, which leads to different temperatures in the top drive gearbox. The existing cooling device cannot adjust in real time to the actual working conditions of the top drive and can only operate at full power under working frequency conditions, resulting in unnecessary energy waste and shortened life. Summary of the Invention

[0004] The object of the present invention is to provide a top drive gearbox adaptive temperature regulation control device and temperature regulation control method, which can adaptively adjust the temperature of the top drive gearbox according to working conditions, reduce resource waste and increase service life.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0034] like Figure 1 and Figure 2 As shown, the present application provides an adaptive temperature regulation control device for a top drive gearbox, which is used to adaptively control the temperature of a top drive gearbox 1, and includes a temperature monitoring component 2, a load monitoring component 3, a heat dissipation component 4, a pumping component 5 and a control component 6. The monitoring end of the temperature monitoring component 2 is placed in the top drive gearbox 1; the monitoring end of the load monitoring component 3 is connected to the top drive motor; the heat dissipation component 4 is connected to the top drive gearbox 1 through the pumping component 5, and the pumping component 5 can circulate lubricating oil between the heat dissipation component 4 and the top drive gearbox 1, and the heat dissipation component 4 can dissipate heat for the lubricating oil flowing through; the control component 6 is connected to the temperature monitoring component 2 and the load monitoring component 3, and controls at least one of the heat dissipation component 4 and the pumping component 5. The control component 6 can control the temperature of the top drive gearbox 1 by controlling at least one of the heat dissipation power of the heat dissipation component 4 and the pumping power of the pumping component 5 according to the monitoring results of the temperature monitoring component 2 and the load monitoring component 3.

[0035] It should be noted that, depending on the different working conditions on site, the top drive motor load is different, that is, the output torque and power of the top drive motor are different; and the transmission power and temperature load of the top drive gearbox 1 are also different.

[0036] Thus, the real-time temperature of the top drive gearbox 1 can be monitored in real time by the temperature monitoring component 2, and the load monitoring component 3 can monitor the load of the top drive motor in real time, so that the ideal equilibrium temperature of the top drive gearbox 1 under the load condition can be known according to the load result, and then the control component 6 can at least control the heat dissipation power of the heat dissipation component 4 and the pumping power of the pumping component 5 (that is, adjust one parameter of the temperature and flow rate of the lubricating oil) to achieve that when different working conditions lead to different loads of the top drive motor, and thus lead to different real-time temperatures of the gearbox, it can adaptively adjust the top drive gearbox 1 to maintain or approach the ideal equilibrium temperature, thereby reducing resource waste and improving service life.

[0037] In some embodiments, the control component 6 may be, but is not limited to, a PLC or the like.

[0038] like Figure 2 As shown, in some embodiments, the monitoring end of the temperature monitoring component 2 is arranged in the oil pool 11 of the top drive gearbox 1, so as to reflect the real-time temperature of the top drive gearbox 1 through the temperature of the lubricating oil entering the oil pool 11, and transmit it to the control component 6 through the data line. The way in which the temperature monitoring component 2 is arranged in the top drive gearbox 1 is not limited. The current embodiment adopts a sealed plug-in form.

[0039] During normal operation, the top drive motor's output torque and power vary, and its current also varies. In some embodiments, the load monitoring element 3 is a current monitoring element, whereby the current value of the top drive motor directly reflects the top drive motor's driving power. In other embodiments, a speed monitoring element may be used, whereby the top drive motor's speed reflects the driving power.

[0040] like Figure 1 As shown, in some embodiments, the control component 6 controls the connection to the heat dissipation component 4, and then controls the heat dissipation efficiency of the heat dissipation component 4 through the control component 6, thereby controlling the temperature of the lubricating oil flowing through the top drive gearbox 1 without changing the pumping power, so as to adjust the temperature of the top drive gearbox 1; in other embodiments, the control component 6 controls the connection to the pumping component 5, and then controls the flow rate of the lubricating oil flowing through the top drive gearbox 1 by changing the pumping power without changing the heat dissipation efficiency, so as to adjust the temperature of the top drive gearbox 1; and in the current embodiment, in order to improve the efficiency of temperature control, a combination of the two is adopted, that is, the control component 6 is connected to both the heat dissipation component 4 and the pumping component 5.

[0041] Furthermore, the heat dissipation assembly 4 includes a radiator 41 and a cooling element 42. The radiator 41 is connected to the oil inlet and oil outlet of the top drive gearbox 1, so that the lubricating oil passes through the top drive gearbox 1 and reaches the radiator 41 for heat dissipation. The cooling element 42 is connected to the radiator 41 to cool the radiator 41 and quickly exchange the heat of the lubricating oil in the radiator 41 to the external environment. More specifically, the radiator 41 is a disc-type radiator, thereby improving the heat dissipation efficiency; the cooling element 42 includes a first inverter 421 and a fan 422. The first inverter 421 is connected to the fan 422. The control assembly 6 is connected to the first inverter 421. The control assembly 6 controls the first inverter 421 to control the speed of the fan 422, thereby controlling and changing the heat dissipation power of the radiator 41. In other embodiments, the cooling element 42 can be water-cooled to perform water-cooled heat dissipation.

[0042] In some embodiments, the pumping assembly 5 includes a second frequency converter 51 and an oil pump 52. The control assembly 6 is connected to the second frequency converter 51. The oil pump 52 is installed on the outside of the top drive gearbox 1 and is connected between the radiator 41 and the top drive gearbox 1. The oil pump 52 draws oil from the oil outlet of the oil pool 11 through an oil suction pipe and injects it into the radiator 41. After heat is dissipated by the radiator 41, the oil is injected into the oil inlet of the top drive gearbox 1. The control assembly 6 controls the speed of the oil pump 52 through the second frequency converter 51 to control the flow rate of lubricating oil pumped by the oil pump 52, thereby controlling the pumping power.

[0043] The present application also provides a temperature regulation control method, which utilizes the above top drive gearbox adaptive temperature regulation control device, and includes the following steps:

[0044] The temperature monitoring component 2 monitors the real-time temperature T1 of the top drive gearbox 1;

[0045] The load monitoring component 3 monitors the load parameter A1 of the top drive motor. After obtaining the load parameter A1, the control component 6 compares the load parameter A1 with a parameter-temperature correspondence model pre-stored in the control component 6 to obtain an ideal equilibrium temperature T0. It should be noted that the parameter-temperature correspondence model is a preset model that can be adjusted to adapt to the temperature value in the state according to the load parameters of different types of top drive motors.

[0046] If T1≠T0, the difference between the ideal equilibrium temperature T0 and the real-time temperature T1 is compared, and the control component 6 adjusts the temperature of the top drive gearbox 1 from T1 to T0 by at least one of the following methods:

[0047] The control component 6 adjusts the speed of the fan 422 in the heat dissipation component 4 through the built-in fuzzy self-tuning PID algorithm model to control the heat dissipation power output of the heat dissipation component 4;

[0048] The control component 6 adjusts the rotation speed of the oil pump 52 in the pumping component 5 through the built-in fuzzy self-tuning PID algorithm model to control the pumping power of the output pumping component 5.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
