Abstract

The invention discloses a deep sea oil field wellhead blowout preventer emergency sonar monitoring system which comprises an underwater unit (1) installed on a wellhead emergency well plugging device (3) and a deck unit (2) placed on a water surface platform (4). The underwater unit (1) and the deck unit (2) work cooperatively to achieve remote underwater sound remote control of user instructions and real-time underwater sound remote measurement of wellhead state parameters, and the underwater unit (1) and the deck unit (2) achieve remote underwater sound remote control and real-time underwater sound remote measurement in an underwater sound coding communication mode. The device is simple in structure, novel and reasonable in design and easy to operate, is controlled to complete timely underwater sound remote control of underwater wellhead sensing data and timely complete real-time underwater sound remote measurement of underwater state parameters, has the functions of real-time display of a deep sea field light-operated visual instrument, automatic switching of an inner battery and an outer battery and the like, and has better redundancy and reliability.

Description

Technical field [0001] The present invention relates to a monitoring system and method, and in particular, it is related to a deep sea oilfield wellhead anti-blower emergency sound monitoring system, mainly for emergency and safety control of wellheads in deep sea oilfield, belonging to deep sea water telemetry and remote control technology field. Background technique [0002] In general, the APIRP17W (US Petroleum Association Norms - Control System Specification for Drilling Control Equipment) The underwater anti-engaging system must be equipped with emergency alternate control systems to ensure the safety of drilling platforms. Underwater anti-engaging machine emergency alternate control system is also known as the underwater anti-engaging emergency safety control system, is a secondary intervention system to respond to marine drilling bursts. The system is different from the emergency sealing device used by the rescue, and the use phase of the two is different. Underwater anti...
