[0002] Currently, during well testing, operators are required to climb and stand on high-pressure blowout preventers to lift and lower wellbore instruments and perform other operations. Since the blowout preventer is installed at the top of the wellhead more than two meters above the ground, frequent lifting and lowering of the nearly two-meter-high blowout preventer and manual clamping of the blowout preventer result in weak support points, a narrow construction area, large limitations, and a low safety factor for stable operation, which can easily cause testers to fall and suffer personal injury accidents. Therefore, an operating platform is required for operation.

Hand wheels 635 are fixedly installed at both ends of the bidirectional threaded rod 632, and a rotating handle 636 is fixedly installed on the top of the screw 62.

[0032] It should be noted that when in use, the entire platform is pushed to the wellhead of the test well, and then the appropriate docking angle is selected according to the pipeline equipment on site, and the lifting rod 2 is controlled to slide on the support column 12, and the distance between the top plate 3 and the base plate 1 is adjusted so that the height of the platform is compatible with the equipment height of the wellhead. When docking, first hold the rotating handle 636 to drive the screw 62 to rotate, thereby driving the lifting seat 631 to slide up and down along the support rod 13, so that the two clamping blocks 634 are located at the appropriate position of the wellhead pipeline, and then turn the handwheel 635 to drive the bidirectional threaded rod 632 to rotate, and the bidirectional threaded rod 632 drives the two clamping blocks 634 to approach each other along the lifting seat 631 until the wellhead pipeline is clamped by the clamping groove, thereby completing the docking of the platform and the wellhead pipeline, and then use the escalator 4 to perform climbing operations, and use the lifting assembly 5 to lift and install equipment.

[0033] In the embodiments of the present invention, please refer to Figures 1 to 5 , a plurality of positioning holes 201 are evenly opened on the lifting rod 2, and a pin 121 that is plugged into the positioning hole 201 is threadedly installed on the top of the support column 12;

A locking plate 511 is installed on the top of the sliding seat 51, and a locking bolt 512 is installed on the locking plate 511. The inner side of the guardrail 31 is evenly provided with a plurality of threaded holes 302 that threadably cooperate with the locking bolt 512.

[0037] It should be noted that when the lifting assembly 5 is in use, first release the restriction of the locking bolt 512 on the locking plate 511, so that the sliding seat 51 can be pulled to slide along the T-slot 301, thereby adjusting the lifting position. After adjustment, the restriction of the limiting bolt 55 on the limiting plate 54 is released, and then the suspension arm 52 can be freely rotated, so that the lifting angle can be adjusted. After sliding to the top of the guardrail 31, it can be rotated to the side facing the wellhead. After rotation, the limiting bolt 55 can be inserted into the limiting hole 501, and then the lifting pulley 53 can be used in conjunction with telescoping to carry out the lifting and installation of the equipment.

[0041] It should be noted that the counterweight water tank 9 is provided with a water inlet end and a drainage end. When transportation is required, the water in the counterweight water tank 9 is discharged to reduce the weight. After docking and installation, the counterweight water tank 9 can be refilled with water to increase the overall weight, which is convenient for pressing the entire platform when the lifting equipment is used.

[0042] The working principle of the well testing operation platform structure provided by the utility model is as follows:

[0043] When in use, push the entire platform to the wellhead of the test well, then select the appropriate docking angle according to the on-site pipeline equipment, and control the lifting rod 2 to slide on the support column 12. When the lifting rod 2 is adjusted up and down along the support column 12, the pin 121 is inserted into the adjusted positioning hole 201 to adjust the limit fixation, and the distance between the top plate 3 and the base plate 1 is adjusted so that the height of the platform is adapted to the height of the equipment at the wellhead. When docking, first hold the rotating handle 636 to drive the screw 62 to rotate, thereby driving the lifting seat 631 to slide up and down along the support rod 13, so that the two The first clamping block 634 is located at a suitable position on the wellhead pipe, and then the hand wheel 635 is turned to drive the bidirectional threaded rod 632 to rotate. The bidirectional threaded rod 632 drives the two clamping blocks 634 to move closer to each other along the lifting seat 631 until the wellhead pipe is clamped by the clamping groove, thereby completing the docking of the platform and the wellhead pipe. Then, the escalator 4 is used for climbing operations, and the lifting assembly 5 is used to lift and install equipment. Furthermore, after docking and installation, the counterweight water tank 9 can be refilled with water to increase the overall weight, which is convenient for pressing and fixing the entire platform when lifting equipment;

[0044] When the lifting assembly 5 is in use, first release the restriction of the locking bolt 512 on the locking plate 511, so that the sliding seat 51 can be pulled to slide along the T-slot 301, thereby adjusting the lifting position. After adjustment, the restriction of the limiting bolt 55 on the limiting plate 54 is released, and then the suspension arm 52 can be freely rotated, so that the lifting angle can be adjusted. After sliding to the top of the guardrail 31, it can be rotated to the side facing the wellhead. After rotation, the limiting bolt 55 can be inserted into the limiting hole 501, and then the lifting pulley 53 can be used to cooperate with the telescopic movement to lift and install the equipment.
