Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] During drilling or workover operations, it is necessary to transfer pipe strings at the wellhead of the drilling floor. This process mainly involves the transfer of pipe string holding authority between hydraulic elevators and power slips.

[0023] refer to figure 2 , is the mechanism layout involved in the handover process of the pipe string at the wellhead position of the drilling floor. The power slip 3 is installed at the wellhead position of the drilling floor 1, and the pipe string 2 extends to the inside of the wellbore through the power slip 3; the traveling crane of the drilling rig or workover rig The mechanism is connected with a lifting ring 5, and the lower end of the lifting ring 5 is hung with a hydraulic elevator 4, and the hydraulic elevator 4 hangs the pipe column 2 to move up and down with the traveling crane mechan...

Abstract

The invention discloses a wellhead pipe string handover interlock management and control device for a drilling rig and a workover rig. The pipe string interlock control system includes a PLC controller, an industrial Ethernet gateway, a DC power supply, a PLC controller, an industrial Ethernet gateway, The DC power supply is installed in the control box; the DC power supply is responsible for converting the AC alternating current into 24V DC control power to supply power to the PLC controller and industrial Ethernet gateway; the PLC controller is responsible for the control program in the string interlock control system Logic operation; the industrial Ethernet gateway is connected with the hydraulic elevator electric control, power slip electric control, winch electric control, man-machine interface unit and PLC controller through PROFINET communication cables. The invention also discloses a method for interlocking and interlocking management and control of wellhead pipe strings of a drilling rig and a workover rig. The above-mentioned device is used to realize process control. The device of the invention realizes the safety interlock of equipment operation in the handover process of the wellhead pipe string; the method can automatically judge whether the pipe string is handed over successfully.

Description

technical field [0001] The invention belongs to the technical field of electrical control of petroleum machinery, and relates to a wellhead pipe string handover and interlock control device for a drilling rig and a workover rig, and also relates to a wellhead pipe string handover and interlock control method for a drilling rig and a workover rig. Background technique [0002] Oil drilling rigs and workover rigs handle drill pipes, drill collars, and tubing (collectively referred to as pipe strings) throughout the entire drilling and workover process. For drilling conditions, before drilling, the pipe string needs to be transported from the ground storage yard to the drill floor surface and the stand is stored on the stand; during the drilling process, frequent tripping is required, and this process involves placing the pipe string between the stand discharge area and the wellhead After the completion of drilling, the pipe string needs to be lifted out of the well and disasse...
