Management and control device and method for drilling machine and workover rig wellhead pipe column handover and interlocking

Abstract

The invention discloses a management and control device for drilling machine and workover rig wellhead pipe column handover and interlocking. A pipe column interlocking control system internally involves a PLC, an industrial Ethernet gateway and a DC power supply, wherein the PLC, the industrial Ethernet gateway and the DC power supply are arranged in a control box; and the DC power supply is responsible for converting alternating current into 24V DC control power to supply power to the PLC and the industrial Ethernet gateway, the PLC is responsible for logical operation of a control program in the pipe column interlocking control system, and the industrial Ethernet gateway is connected with a hydraulic elevator electric controller, a power slip electric controller, a winch electric controller, a human-computer interface unit and the PLC through PROFINET communication cables. The invention further discloses a management and control method for drilling machine and workover rig wellheadpipe column handover and interlocking, and process control is achieved through the device. By means of the device, safety interlocking of equipment operation in the wellhead pipe column handover process is achieved; and the method can automatically judge whether a pipe column 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...
