Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting.

This document replaces GB/T 22342-2008 "Design, installation, operation and maintenance of downhole safety valve systems for oil and gas industry Compared with GB/T 22342-2008, except for structural adjustment and editorial changes, the main technical changes are as follows:

a) Changed the general rules of downhole safety valves (see 4.3.1.1.1, 5.2.2.7 of the 2008 edition);

b) Added structural requirements for plug-in downhole safety valves (see 4.3.1.1.3);

c) Changed the surface control downhole safety valve system diagram (see Figure 1, Figure 1 of the 2008 edition);

d) Increase the design and maintenance requirements of auxiliary tools for downhole safety valves (see 4.3.3.2, 7.3);

e) Changed the installation steps of the ground control downhole safety valve (see Chapter 5, 5.2.2, Appendix C of the 2008 edition);

f) Added the steps of on-off test before installation of the ground-controlled downhole safety valve, on-well test, and on-off flexibility test during production (see 5.2, 6.3.3);

g) The test requirements for downhole control safety valves and injection safety valves have been added (see 6.4);

h) Deleted Appendix A "SSSV Maintenance Report (Basic Information Requirements)" (see Appendix A of the 2008 edition).

1 Scope

This document specifies the application design, installation, operation, test, maintenance and other requirements of the downhole safety valve system.

This document is applicable to the application of the downhole safety valve system, not to the manufacturing design, evaluation and repair of the downhole safety valve.
