[0032] In this application, all drawings are schematic and are used only to illustrate the principles of the invention, and are not drawn to scale. Detailed Implementation

[0033] The invention will now be described with reference to the accompanying drawings.

[0034] It should be noted that the directional terms or qualifiers used in this application, such as "up," "down," "front," "back," "left," and "right," are all in relation to the accompanying drawings. They are not used to define the absolute position of the components involved, but can vary depending on the specific circumstances.

[0035] like Figure 1 and Figure 2 As shown, the hydraulic power integrated control system includes a ground hydraulic station 1 and a drilling platform hydraulic station 2.

[0036] Among them, such as Figure 2 As shown, a skid 131 is provided on the side of the base 132 of the drilling rig. The skid 131 is fixedly provided on the side of the base 132, and the skid 131 can move with the drilling rig when the drilling rig moves.

[0037] The ground hydraulic station 1 is fixedly mounted on the skid 131. The ground hydraulic station 1 provides hydraulic power to the ground equipment of the drilling rig.

[0038] In this embodiment, the ground equipment includes any one or more of the following: a power catwalk 6, a power drill pipe box 5, a power casing box 4, a blowout preventer integral transport mechanism, a drilling rig moving mechanism 7, and a derrick lifting mechanism.

[0039] In a specific embodiment, such as Figure 3 As shown, the ground hydraulic station 1 includes a housing 121, in which an oil tank 125, an oil pump 122 and a ground pipeline interface 127 are installed and connected to each other. The ground pipeline interface 127 is connected to the ground equipment.

[0040] The housing 121 is roughly square in shape. Both the oil tank 125 and the oil pump 122 are located inside the housing 121. A ground pipeline interface 127 is located on the side wall of the housing 121 and connects to the oil tank 125. Ground equipment is connected to the ground pipeline interface 127 via pipelines. After the oil pump 122 starts, it pumps the oil in the oil tank 125 to the ground equipment through the ground pipeline interface 127, thereby providing a hydraulic power source for the ground equipment.

[0041] Furthermore, a power supply cabinet 123 and a low-voltage control cabinet 124 are also installed inside the building 121 to supply power to the ground equipment.

[0042] In one specific embodiment, a communication interface 126 is provided on the housing 121 for connecting to the driller's cabin 321 of the drilling rig, thereby enabling the driller's cabin 321 to remotely control the ground hydraulic station 1.

[0043] In a preferred embodiment, such as Figure 4 As shown, a first backup pipeline interface 128 for connecting to the drilling rig is provided on the ground hydraulic station 1. The first backup pipeline interface 128 is located on the side of the housing 121 of the ground hydraulic station 1. When the drilling rig hydraulic station 2 fails, the drilling rig connects to the ground hydraulic station 1 through the first backup pipeline interface 128, enabling the ground hydraulic station 1 to provide a hydraulic power source to the drilling rig and preventing the drilling rig from becoming inoperable due to maintenance of the drilling rig hydraulic station 2.

[0044] like Figure 1 and Figure 2 As shown, the hydraulic station 2 of the drilling platform is installed on the drilling platform surface 133 of the drilling rig, and the hydraulic station 2 of the drilling platform provides hydraulic power to the drilling platform equipment of the drilling rig.

[0045] In one specific embodiment, the drilling rig equipment includes any one or more of the following: offline iron drill 8, iron drill 9, hydraulic slips 10, hydraulic cat head 12, and casing wrench 11.

[0046] like Figure 2 As shown, a side chamber 211 is provided on the drilling platform surface 133, and the drilling platform hydraulic station 2 is located inside the side chamber 211. The internal structure of the drilling platform hydraulic station 2 is similar to that of the ground hydraulic station 1, and will not be described in detail here.

[0047] In a specific embodiment, such as Figure 5 As shown, a drilling platform pipeline interface 1261 for connecting to the drilling platform equipment and a second backup pipeline interface 1262 for connecting to the ground equipment are provided on the side of the drilling platform hydraulic station 2. When the ground hydraulic station 1 fails, the ground equipment connects to the drilling platform hydraulic station 2 through the second backup pipeline interface 1262, so that the drilling platform hydraulic station 2 can provide a hydraulic power source for the ground equipment, avoiding the ground equipment from becoming inoperable due to maintenance of the ground hydraulic station 1.

[0048] In one specific embodiment, an integrated control system 3 is installed in the driller's cabin 321, and both the surface hydraulic station 1 and the drilling platform hydraulic station 2 are electrically connected to the integrated control system 3 in the driller's cabin 321. The control methods for the surface hydraulic station 1 and the drilling platform hydraulic station 2 include local control and remote control. Remote control refers to setting parameters such as the working pressure and flow rate of each oil pump in the surface hydraulic station 1 and the drilling platform hydraulic station 2 through the integrated control system 3 in the driller's cabin 321.
