The telescopic guide rail 1 of suit and the vertical catwalk 9 of upset all rely on well head location and installation, and pipe/pole is to just well head center when guaranteeing vertical operation, realize vertical taking over, embolia pipe/pole upper portion and upper tube/pole including elevator 12 and are to just low tube/pole, concrete operation: the center of the tail part of the vehicle-mounted workover rig 5 is over against the center of a wellhead, and the distance is adjusted; the derrick of the vehicle-mounted workover rig 5 is lifted, and the inner derrick is lifted; referring to fig. 9, the sleeved telescopic guide rail 1 is lowered, the flexible connecting rope 4.2 is connected with the wellhead guide connecting plate 6, the wellhead connecting and tensioning mechanism 4 is adjusted to be pre-tensioned through the tensioning winch 4.1, the lead screw 3.2 and the nut 3.3 are driven through the stepping motor 3.1, the sleeved telescopic guide rail 1 is supported, and when the elevator 12 falls to the workbench, the center of the elevator 12 is opposite to the center of the wellhead; the vertical catwalk 9 that overturns centre gripping pipe/pole lifts the arm and overturns 90, and lower extreme pipe/pole center is adjusted well head center, and 4 landing legs 9.3 height of the vertical catwalk 9 base 9.1 that overturns realize lifting arm angle, ensure that elevator 12 can embolia pipe/pole upper end smoothly.
The invention provides a use method of a mechanized small repair operation integrated device of a sucker rod based on a vehicle-mounted workover rig, which comprises the following steps:
referring to fig. 2, under the transport condition, the telescopic guide rail 1 of suit and the vertical catwalk 9 of upset are installed in the derrick opening on-vehicle workover rig 5, and the derrick on the last slide rail 1.1 one end of telescopic guide rail 1 of suit and the on-vehicle workover rig 5 is connected, and one end is connected tensioning mechanism 4 and well head direction connecting plate 6 through the well head and is connected, and the connection this moment is the flexible coupling. An elevator 12 and a slip and make-up mechanism 11 are placed at the tail of the vehicle-mounted workover rig 5.
Referring to fig. 3-5, 10, 12 and 13, when the vehicle-mounted workover rig 5 reaches a specified position, the elevator 12 and the slip and upper shackle mechanism 11 are moved out of the vehicle-mounted workover rig 5 and placed on the ground, the derrick on the vehicle-mounted workover rig 5 starts to slowly turn over to the specified position under the action of the hydraulic cylinder, and the turning vertical catwalk 9 is raised along with the hydraulic cylinder. When the derrick reaches the set position, the hydraulic cylinder on the vehicle-mounted workover rig 5 stops working, and the winch hangs the hanging ring at the far wellhead end of the turnover vertical catwalk 9 to move downwards. When moving to the appointed position down, pass through bolted connection with earring 6.1 on the well head guide connection board 6 and the big cross-joint of well head, simultaneously with well head guide connection board 6 with upset vertical catwalk 9 through well head positioning pin 7 be connected. When the turnover vertical catwalk 9 reaches a preset position, the winch continues to move downwards, and the turnover vertical catwalk 9 turns over for 90 degrees by taking the wellhead positioning pin shaft 7 as a supporting point to reach a pre-working position of the turnover vertical catwalk 9. The well head workman takes off the winch from the rings of upset vertical catwalk 9, installs well head catwalk location backup pad 8, and upset vertical catwalk guiding mechanism 10 adjusts upset vertical catwalk 9 and well head center fore-and-aft distance can realize the sucker rod and slips and go up break-out mechanism 11, elevator 12 coaxial line after guaranteeing upset arm upset 90 on the vertical catwalk 9 of upset.
Referring to fig. 1, 5, 8, 9 and 12, after the arrangement of the turnover vertical catwalk 9 is completed, the derrick is extended to a predetermined position by the hydraulic cylinder and then the hook starts to operate. And (3) installing the elevator guide mechanism 13 on the sleeved telescopic guide rail 1 from the lower end of the lower slide rail 1.2, and continuing to install the elevator 12 after the installation of the elevator guide mechanism 13 is completed. After the elevator 12 is installed, the hook lifts the elevator 12 to the highest point to be ready for installing the slips and the upper tripping mechanism 11, and the slips and the upper tripping mechanism 11 are installed on a small four-way of a wellhead. After the installation process of all the devices is completed, the height of the human-shaped support 2 is adjusted by the human-shaped support adjusting mechanism 3, and the vertical direction angle of the sleeved telescopic guide rail 1 is further adjusted to ensure that the elevator 12 is coaxial with the wellhead device. After the centering action is finished, the wellhead connecting and tensioning mechanism 4 installed on the mounting plate 6.2 starts to tension to fix the upper sliding rail 1.1. And the installation of the pumping rod workover equipment is completed.
Referring to fig. 1 and 6, in the process of lifting the sucker rod, the hook drives the elevator 12 to descend along the sleeved telescopic guide rail 1 to the upper end surface of the slip and upper shackle mechanism 11. After the sucker rod is clamped, the elevator 12 moves upwards, the slips and the slips in the upper shackle mechanism 11 are opened, the elevator 12 firstly moves from the bottom end of the lower slide rail 1.2 of the sleeved telescopic guide rail 1 to the top end of the lower slide rail 1.2, the hook continues to move upwards after the top end is reached, and the lower slide rail 1.2 of the sleeved telescopic guide rail 1 integrally moves upwards along the upper slide rail 1.1 to reach the initial position. In the process of moving the elevator 12 upwards, the mechanical arm on the turnover vertical catwalk 9 starts to turn over, when the elevator 12 reaches the initial position, the mechanical arm on the turnover vertical catwalk 9 completes 90-degree turnover action, a manipulator on the mechanical arm flexibly clamps the sucker rod, the elevator 12 loosens the sucker rod and continues to move upwards, a screwing-on and unscrewing clamp in the slip and screwing-on and unscrewing mechanism 11 completes screwing-on and unscrewing action and returns, the manipulator on the mechanical arm clamps the sucker rod firmly, and the mechanical arm returns to complete the process of pulling up the sucker rod. The process of pumping down the sucker rod is opposite to that of pumping up the sucker rod, so the process is not described in detail herein.
The above description is only a few of the preferred embodiments of the present invention, and any person skilled in the art may modify the above-described embodiments or modify them into equivalent ones. Therefore, the technical solution according to the present invention is subject to corresponding simple modifications or equivalent changes, as far as the scope of the present invention is claimed.
