Gas Well Safety Control Technology

Increasingly serious security problems for gas production, as this paperresearch studies on this topic, literature review, wellhead and surface safetyvalves, safety valves and down hole packer down hole equipment such. On thisbasis, the paper design to Zijin Bridge6.0software for the PC industrial gassafety control system.The system has a down hole packer, ground safety valve and subsurfacesafety valve airtight, watertight better performance characteristics; Surface anddown hole safety valve while the system valve opening and closing functionwell, flexibility and reliability; The system also enables the control system onthe ground floor and down hole safety valve shutoff valve and open the controlaction. In order to achieve better security control, in this paper, the system isalso an indoor test conditions and field application conditions studied, proposedtechnical requirements for safety testing.The gas safety control system can satisfy the requirements of oil fieldwells, improve the safety and stability of the gas, ensure the safety and securityof residents’ oilfield production, has a good promotion prospects, and able toachieve greater economic and social benefits.
