[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0024] See also Figures 1 to 4 The embodiment of the present invention provides an integrated skid for water plugging and profile control, the integrated skid for water plugging and profile control comprising:
[0025] A base 1, and locking universal wheels 11 provided at the four corners of the bottom end of the base 1;
[0026] The middle partition 2 is fixedly installed on the middle part of the bottom end of the base 1, and support rods 3 are symmetrically installed on both sides of the middle partition 2, a sliding frame 4 is slidably installed on the support rod 3, and a gathering tube 5 is fixedly installed on the sliding frame 4. One end of the gathering tube 5 is connected to a connecting elbow 51, and several specifications of transfer tubes 6 are installed on the gathering tube 5, and several transfer tubes 6 are installed with sealing parts 7. The sealing parts 7 include mounting tubes 71 corresponding to several transfer tubes 6, a threaded sleeve 72 is rotatably installed in the mounting tube 71, a screw 73 is threadedly installed in the threaded sleeve 72, and a sealing head 74 for sealing the transfer tube 6 is installed at one end of the screw 73, and a limiter 8 for limiting the rotation of the screw 73 is installed on the sliding frame 4.
[0027] The limiting member 8 includes a support frame 81 , which is fixedly mounted on the sliding frame 4 , and a plurality of hexagonal rods 82 are mounted on the support frame 81 . The screw rod 73 is provided with a hexagonal countersunk hole that is plugged into the hexagonal rod 82 .
[0028] It should be noted that: when in use, various devices for water plugging and profile control are installed on the upper surface of the base 1, and then the liquid outlet of the water injection and the plugging agent are respectively installed on the connecting elbows 51 on the sliding frames 4 at both ends using metal corrugated hoses. Then, when it is moved to the oil field construction site, a corresponding specification of the transfer pipe 6 is selected according to the on-site water injection pipeline, and then the threaded sleeve 72 on the transfer pipe 6 is rotated. When the threaded sleeve 72 rotates, the driving screw 73 slides along the threaded sleeve 72 under the limit of the limiter 8, and the plugging head 74 is driven to withdraw from the transfer pipe 6 during the sliding, and the corresponding transfer pipe 6 is opened;
[0029] When the limiter 8 is in use, the hexagonal rod 82 is plugged into the hexagonal countersunk hole of the screw 73 to limit the screw 73 to slide only along the hexagonal rod 82. When sliding, the switch scale mark 821 is used to observe the switch status of the corresponding transfer tube 6.
[0030] In this embodiment, a switch scale mark 821 is engraved on the upper surface of the hexagonal rod 82 .
[0031] In the embodiments of the present invention, please refer to Figures 1 to 4 The plugging head 74 is in an I-shape with a thin middle and thick ends, and both ends of the plugging head 74 are slidably matched with the corresponding transfer tube 6;
[0032] The inner diameter of the adapter tube 6 is equal to the inner diameter of the corresponding mounting tube 71 .
[0033] It should be noted that: when the I-shaped plugging head 74 slides, one end of the plugging head 74 either slides into the transfer tube 6 or into the mounting tube 71, while not blocking the water flow, so that the movement of the plugging head 74 is more stable.
[0034] In the embodiments of the present invention, please refer to Figures 1 to 4 A hand wheel 75 is fixedly mounted on one end of the threaded sleeve 72 , and an outer side wall of the hand wheel 75 is provided with anti-slip grooves.
[0035] It should be noted that the hand wheel 75 is provided with anti-skid grooves to increase friction so that the hand wheel 75 can be held by hand to drive the threaded sleeve 72 to rotate.

[0037] It should be noted that when the sliding frame 4 is pulled out and slid, it can slide synchronously with the support of the supporting legs 41 and the rollers 42 , thereby improving the support strength of the sliding frame 4 .
[0038] The working principle of the integrated skid for water plugging and profile control provided by the utility model is as follows:
[0039] During use, various devices for water plugging and profile control are installed on the upper surface of the base 1, and then the liquid outlet of the water injection and the plugging agent are respectively installed on the connecting elbows 51 on the sliding frames 4 at both ends using metal corrugated hoses. Then, when it is moved to the oil field construction site, a transfer pipe 6 of corresponding specifications is selected according to the on-site water injection pipeline, and then the handwheel 74 of the threaded sleeve 72 on the transfer pipe 6 is turned to drive the threaded sleeve 72 to rotate. When the threaded sleeve 72 rotates, the driving screw 73 slides along the threaded sleeve 72 under the limit of the limiter 8, and the plugging head 74 is driven to withdraw from the transfer pipe 6 during the sliding, and the corresponding transfer pipe 6 is opened.
[0040] When the limiter 8 is in use, the hexagonal rod 82 is plugged into the hexagonal countersunk hole of the screw 73 to limit the screw 73 to slide only along the hexagonal rod 82. When sliding, the switch scale mark 821 is used to observe the switch status of the corresponding transfer tube 6.
