Remote control device and method of offshore oil and gas well safety valve

Abstract

The invention relates to a remote control device and a method of an offshore oil and gas well safety valve, belonging to the field of safety valve remote control. The remote control device of the offshore oil and gas well safety valve comprises a master control center upper computer, GPRS (General Packet Radio Service) modules, antennae, a safety valve single chip control device and electromagnetic relays, wherein the land master control center upper computer is sequentially connected with a first GRPS module, a first antenna, a second GPRS module, a second antenna, the safety valve single chip control device, a first electromagnetic relay, a second electromagnetic relay and a third electromagnetic relay; the three electromagnetic relays are in parallel connections; and the first electromagnetic relay is connected with a subsurface safety valve, the second electromagnetic relay is connected with a wellhead safety valve, and the third electromagnetic relay is connected with a well casing safety valve. The invention improves the safety and the automation level of the production of the offshore oil and gas well platform, and has the advantages of powerful function, simple installation, convenient use, safety and reliability.

Description

technical field [0001] The invention belongs to the field of remote control of safety valves, in particular to a remote control device and method for safety valves of offshore oil and gas wells. Background technique [0002] The control of offshore oil and gas well safety valves includes the control of downhole safety valves, wellhead safety valves and well casing safety valves, and the emergency shutdown of oil and gas wells is realized by closing each safety valve. Existing safety valve control devices generally only have on-site control functions, which are performed manually or automatically according to set conditions. Manual operation means that technicians manually operate the safety valve control device according to the site conditions. This method has the advantages of simple operation and fast response, but it also has disadvantages: the production environment of offshore oil and gas well platforms is very harsh, and the personal safety of production workers Safet...

Problems solved by technology

Manual operation means that technicians manually operate the safety valve control device according to the site conditions. This method has the advantages of simple operation and fast response, but it also has disadvantages: the production environment of offshore oil and gas well platforms is very harsh, and the personal safety of production workers Safety is always threatened. When an emergency occurs and people need to evacuate immediately, casualties, environmental pollution, and economic losses may occur due to the inability to shut down oil and gas wells immediately.
