Embodiment Construction

[0014] see figure 1 . The linear motor-based deepwater blowout preventer group control system of the present invention mainly includes a central control unit 1 located on the platform, a blue box 3 and a yellow box 5 located underwater, and an optical cable 2 connected to the above-water and underwater systems.

[0015] see figure 2 . The central control unit 1 is the core of the control system, and it mainly includes a driller's console 6 , a captain's console 7 , a workstation 8 , a triple-mode redundant controller 9 , a VPN server 10 , a photoelectric converter 11 and a database server 12 . The driller's console 6 includes a touch-screen industrial computer and a button panel. As the first control station, it can complete all the functions of the control system; the driller can control the blowout preventer group and the underwater riser by using the monitoring software running on the industrial computer All the functions of the assembly (LMRP), and the data in the data...

Abstract

The invention belongs to the deep-water drilling device control field, and relates to a linear motor-based deep-water blowout preventer group control system, which mainly comprises a central control unit (1), an underwater control box blue box (3), an underwater control box yellow box (5) and a connection optical cable (2). The central control unit (1) is core for controlling the system and is used for transmitting an order and for providing a communication interface, and a driller console (6), a team leader console (7) and a workstation (8) which are arranged inside the central control unit (1) are respectively used as a main control station, a second control station and a third control station and are arranged on a platform. The control box blue box (3) and the control box yellow box (5) are backed up to each other, and the two control boxes are mainly and respectively provided with an identical photoelectric converter (11), an input-output module (13), a linear motor drive device (14) and a temperature pressure sensor (15) and are used for controlling and detecting a blowout preventer group. The linear motor-based deep-water blowout preventer group control system has advantages that: the long distance transportation and rapid transportation can be realized; the structure is simple, and the cost is low; the system is rapid to install, less time is spent to locate and repair the malfunction, and the modularization can be realized.

Description

technical field [0001] The invention belongs to the field of deepwater drilling equipment control, and relates to a deepwater blowout preventer group control system based on a linear motor. Background technique [0002] The deepwater blowout preventer unit plays an extremely important role in ensuring the safety of deepwater drilling operations. Its function is to control the wellhead pressure when a blowout or kick occurs, and to close the wellhead when the drilling device must be evacuated in emergency situations such as typhoons to ensure that personnel and equipment safety, while avoiding pollution of the surrounding marine environment and damage to oil and gas resources. At present, hydraulically driven blowout preventers are used in deepwater drilling. For this type of blowout preventer, in API Spec 16D (Second Edition), three different underwater blowout preventer control systems are described, namely, the pilot Hydraulic control system, electro-hydraulic control sys...
