Introduction
1. Standard background and technical evolution
GB/T22342-2022 "Design, installation, operation, testing and maintenance of downhole safety valve systems for petroleum and natural gas drilling and production equipment" was issued in 2022, replacing the old standard in 2008. The new standard has made a number of technical improvements on the original basis, including adding structural requirements for plug-in downhole safety valves, optimizing the installation steps of ground-controlled downhole safety valves, and strengthening the fault reporting mechanism.
2. Key points of system design
| Design dimensions | Technical requirements | Improvements |
|---|---|---|
| Basic data collection | Including key parameters such as well location, casing size, and working pressure. | Added requirements for acid fracturing pump pressure and fluid temperature. |
| System composition | Downhole equipment and tools, surface equipment and supporting tools and equipment. | Added design specifications for subsea safety valves and their actuators. |
| Material selection | Meet the technical requirements of system functions and use environment. | Optimized the selection criteria of control fluid, and added corrosion and compatibility assessment. |
3. Installation and operation specifications
Actual application case: Ground control downhole safety valve installation steps
Step 1:Perform a switch function test before installation to ensure the normal performance of the valve.
Step 2:Perform a functional test again after entering the well to confirm that there is no leakage and the operation is flexible.
Step 3:When the control pipeline passes through the tubing hanger, pay attention to the installation of the sealing joint to prevent liquid leakage.
4. Maintenance and test requirements
- The equipment after maintenance must comply with the current national or international standards.
- The maintenance of the downhole safety valve is limited to replacing the seals, and it is prohibited to disassemble the internal connection of the valve body.
- Perform a switch test and leakage check every 6 months, and the longest time shall not exceed 12 months.
5. Implementation suggestions
Suggestion 1:When selecting a downhole safety valve, fully consider the corrosiveness of the wellbore environment, the properties of the fluid and the working pressure.
Suggestion 2:Establish a complete document management system to record maintenance history, test results and fault analysis reports.
Recommendation 3: Regularly calibrate and check the control system to ensure the accuracy and reliability of the measuring device.
Summary
GB/T22342-2022 standard provides comprehensive technical specifications for downhole safety valve systems in oil and gas drilling equipment. Through scientific design, standardized installation, strict testing and timely maintenance, the safe operation of oil and gas wells can be effectively guaranteed.
