Embodiment Construction

[0017] See attached figure 1 A camera 2 is installed in the middle of the tail of the car body system 1, and the tail image when it is reversing can be transmitted to the display screen in the cab. According to the pointer 4 on the derrick alignment device 3 and the pointer 6 on the wellhead alignment device 5 seen on the display screen, the driver aligns the vehicle body and the wellhead in the width direction of the vehicle body.

[0018] Keep the correct direction and continue to reverse slowly, when the cross mark in the camera 7 on the derrick alignment device 3 is aligned with the cross mark on the reflection seat 8 on the center of the wellhead alignment device 5 . This process can be shown on the display screen in the cab. Since the center distance A from the center of the derrick system 9 to the center of the derrick turning hinge 10 is fixed, the center of the cross cursor in the camera 7 on the derrick alignment device 3 is installed at a position B from the center...

Abstract

The invention discloses a fast wellhead butting device which comprises a vehicle body and a derrick. The derrick is placed on the vehicle body through a hydraulic lifting cylinder, an overturning hinge and a supporting rod; a camera is mounted at the tail of the vehicle body, a derrick bottom plate is mounted at the tail end of the derrick, and a derrick aligning device provided with a pointer anda camera is mounted in the middle of the derrick bottom plate; the pointer is aligned with a pointer of a wellhead aligning device, the corresponding camera is mounted on the derrick aligning device,and a cross cursor in the camera is aligned with a cross sign on a reflection seat in the center of the wellhead aligning device; the derrick can be rotated to be vertical, and two lifting oil cylinders in the derrick can lift and put down a tubular column combination body in the derrick; and during reversing, a driver fast and correctly determines that the horizontally-arranged derrick is overturned to be vertical through a vehicle body rear-view system, the derrick aligning device and the wellhead aligning device, then correct mounting of positions of connecting holes in a workover equipment flange plate and connecting holes in a wellhead flange plate is realized, and fast and accurate wellhead butting is achieved.

Description

technical field [0001] The invention relates to the technical field of workover operations in oil fields, in particular to a fast wellhead docking device. Background technique [0002] In the process of oil production in an oil field, it is necessary to carry out workover operations on oil wells on a regular basis or according to needs, and replace or repair downhole tools and pipe strings. Regardless of whether it is to perform workover operations on normal temperature snubbing wells or high temperature snubbing wells, it is necessary to have a huge workover operation machine. During workover operations, due to the dispersion of well sites and the complexity of operating conditions, the transportation and installation of workover equipment (including wellhead docking) will consume a lot of time and resources, and there are certain safety hazards. [0003] The current development trend is to integrate workover equipment on a car body to form a vehicle-mounted workover machi...
