Safety assurance method and system for offshore oil well control equipment

Abstract

The invention belongs to the field of marine engineering, and in particular relates to a safety assurance method and system for offshore oil well control equipment. The safety assurance method for offshore oil well control equipment contains five major steps of status identification of the main structure of the offshore oil well control equipment, status identification of a hydraulic control unitof the offshore oil well control equipment, status identification of an electronic control unit of the offshore oil well control equipment, status prediction of the offshore oil well control equipmentand real-time decision based on existing information. The safety assurance system for offshore oil well control equipment comprises a main structure status identification subsystem, a hydraulic control unit status identification subsystem, an electronic control unit status identification subsystem and a status prediction and real-time decision making subsystem. The safety assurance method and system for offshore oil well control equipment provided by the invention have the main advantages of being able to obtain the real-time status of each component, predict the future state of the offshoreoil well control equipment, and make a real-time decision for the current state and the future state to ensure the rapid decision-making of emergency events.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a safety assurance method and system for offshore oil well control equipment. Background technique [0002] With the continuous deepening of the national marine strategy, offshore oil exploitation has become a key topic of the national petroleum strategy, and the development of offshore oil equipment has provided technical support for the offshore oil strategy. Oil drilling accidents will have devastating consequences. Therefore, the exploitation of offshore oil requires highly reliable well control equipment and effective well control equipment maintenance methods. Offshore oil well control equipment generally consists of three major modules: an electronic control system that processes and sends control commands, a hydraulic control system that provides the main control pressure, and a system body that realizes the main tasks. For the detection of well control equi...

AI Technical Summary

Problems solved by technology

[0003] Traditional maintenance methods ensure the safe operation of offshore oil well control equipment to a certain extent. However, regular maintenance methods cannot monitor the real-time status of well control equipment, and it is difficult to make real-time decisions on the drilling process. The state assessment method cannot completely determine the usability and life state of the equipment
