specific Embodiment approach 1
[0036] Combine below Figure 1 to 5 In this embodiment, a split type downhole intelligent sliding sleeve switch includes a switch sliding sleeve 1, a measurement and control assembly 2 and a power supply assembly 3. The switch slide 1, the measurement and control assembly 2 and the power supply assembly 3 are fixedly connected in sequence , The switch sliding sleeve 1 includes a lower joint body 1-1, a sliding sleeve outer body 1-2, a switch valve seat 1-3, a sliding sleeve valve core 1-4 and a drive mounting sleeve connecting body 1-5; The joint body 1-1, the sliding sleeve outer body 1-2 and the drive mounting sleeve connecting body 1-5 are fixedly connected in turn to form the switch sliding sleeve 1; the sliding sleeve valve core 1-4 is slidingly connected in the switch valve seat 1-3 ; The switch valve seat 1-3 is fixedly connected to the inner side of the sliding sleeve housing 1-2;
[0037] The measurement and control assembly 2 includes a lock nut 2-1, a lower sealing bo...
specific Embodiment approach 2
[0043] Combine below Figure 1 to 5 This embodiment will be explained. This embodiment will further explain the first embodiment. The side wall of the sliding sleeve outer casing 1-2 is provided with an outer casing oil hole 1-2-1, and the side of the switch valve seat 1-3 The wall is provided with a valve seat oil hole 1-3-1, and the housing body oil hole 1-2-1 communicates with the valve seat oil hole 1-3-1. The outer casing oil hole 1-2-1 and the valve seat oil hole 1-3-1 are always in communication, and the sliding sleeve valve core 1-4 is driven in the switch valve seat 1-3 through the left and right sliding of the driven valve 2-5 Perform a linear motion to change the position of the sliding sleeve valve core 1-4 on the switch valve seat 1-3, thereby controlling whether the oil hole 1-2-1 of the housing body and the oil hole 1-3-1 of the valve seat communicate with the outside.
specific Embodiment approach 3
[0045] Combine below Figure 1 to 5 This embodiment will be described. This embodiment will further explain the second embodiment. A driven valve oil passage I2-5-1 is formed between the lower sealing body 2-2 of the driven valve and the sealing body 2-3 of the driven valve. The driven valve oil passage II 2-5-2 is formed between the driven valve sealing body 2-3 and the driven valve upper sealing body 2-4, and the driven valve oil passage I 2-5-1 is located in the driven valve At the left end of 2-5, the driven valve oil passage II 2-5-2 is located at the right end of the driven valve 2-5, and the driven valve sealing body 2-3 is provided with a transition oil passage I 2-3-1, The upper sealing body 2-4 of the driven valve is provided with a transition oil passage II 2-4-1, and the left end of the transition oil passage I 2-3-1 communicates with the driven valve oil passage I 2-5-1. The right end of the transition oil passage I2-3-1 is in communication with the transition oil...
