Embodiment Construction

[0014] See attached figure 1 , camera 2 is installed in the center of the tail of the car body system 1 (i.e. the centerline of the derrick system 9), and the tail image during its 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 system 1 (that is, the centerline of the derrick system 9 ) and the wellhead center 14 at the width of the vehicle body. Alignment in direction.

[0015] Keep the correct direction and continue to reverse slowly. When the cross cursor 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, the car body system 1 (that is, the derrick) is ensured. The center line of system 9) is aligned with the wellhead center 14 in the car body length direction, and this process ca...

Abstract

The invention discloses a fast wellhead docking device and its use method. The derrick alignment device is installed in the middle of the derrick bottom plate, and is composed of a support column, a camera and a pointer drooping by gravity. The wellhead alignment device consists of a reflective seat and a center point Composed of a cross mark and a pointer, according to the positioning of the stop on the flange of the wellhead, a camera is installed in the middle of the rear of the vehicle body system, that is, at the centerline of the derrick system, and the rear image of the vehicle during reversing can be transmitted to the display screen in the cab. According to the pointer on the derrick alignment device and the pointer on the wellhead alignment device seen on the display screen, align the vehicle body system and the center of the wellhead in the width direction of the vehicle body. Since the wellhead docking process is completed by human-controlled equipment, only manual operation is required when installing the connecting bolts, which greatly reduces the safety hazards during the installation process.

Description

technical field [0001] The invention relates to the technical field of oil field workover operations, in particular to a fast wellhead docking device and a usage method for a vehicle-mounted workover operation machine. 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 ...
