GB/T 20174-2019Petroleum drilling and production equipment—Drill-through equipment (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 20174-2006 "Drilling and Production Equipment for Oil and Gas Industry Drilling and Passing Equipment". Compared with GB/T 20174-2006, the main technical changes are as follows.

--- Added the relevant content of the integrated BOP;

--- Revised the schematic diagram of the ground drilling equipment and the schematic diagram of the underwater drilling equipment (see Figure 1, Figure 2);

--- Increased the terms and definitions of closure ratio, key areas, critical dimensions, etc.;

--- Increased acronyms such as COC, FAT, MOPFLPS;

--- Increased rated pressure levels of 6.9 MPa (1000 psi) and 172.4 MPa (25,000 psi) (see Table 2);

--- Increased the temperature grade of the metal material, from the original three temperature levels to six, increasing the temperature limit of 177 ° C (See Table 3);

--- Increased the non-metallic seal temperature level to the lowest temperature, continuous high temperature, extreme high temperature representation method, the representation method from the original 2 digits become 3 digits (see Table 4);

--- Increased hydraulic connector requirements for locking (see 5.3.11.7);

--- Increased the requirements for test piles (see 5.4.8);

--- Increased the purpose, procedures, and record requirements for design verification tests such as ring and ram blowout preventers (see 5.7);

--- Increased the design confirmation test content, such as. low pressure seal minimum operating pressure test if the wellbore pressure is zero (see 5.7.3.1.1), Minimum operating pressure test for low pressure seals with well pressure (see 5.7.3.1.2), shear diameter design range test (see 5.7.3.4.2), partial Heart shear test (see 5.7.3.4.3), lateral force shear test (see 5.7.3.4.4), annular blowout preventer extended range operating performance test (see 5.7.3.12);

--- Increased design temperature confirmation test content, such as. annular blowout preventer continuous working temperature design confirmation test (see 5.7.3.17), ring Low-pressure path performance test of the blowout preventer (see 5.7.3.19);

--- Increased the requirements for weld repairs and traceability requirements for metal parts in written specifications (see 6.2.1);

--- Increased the performance requirements of non-standard materials for pressure parts (see 6.3.1, Table 29);

--- Increased material requirements for pressure control parts (see 6.4);

--- Modified the requirements for post-weld heat treatment (7.3.7);

--- Increased the requirements for filling material identification and chemical composition analysis in the performance qualification of the welding process (see 7.4.3);

--- Increased the requirements for visual inspection of welders (see 7.4.8);

--- Increased the hardness test of the surfacing layer (see 7.5.1.2.5);

--- Increased the hardness test requirements for the actual value of the hardness test of pressure parts and pressure control parts at the point of location (see 8.5.1.4); the actual value of the weld hardness test shall be indicated on the part close to the test position (see 8.5.1.16);

--- Increased the content of the diameter test, canceled the 30min aging requirements of the ram blowout preventer (see 8.5.7.4.2);

--- Increased the requirements for the housing gasket area in the bulk hydrostatic strength test (see 8.5.7.6.2);

--- Increased the test requirements for pressure-bearing components when BOP or hydraulic connectors are transported separately (see 8.5.7.8.6);

--- Removed the requirements for the repair and repair of the canonical Appendix B (see Appendix B of the 2006 edition);

--- Deleted the design confirmation procedure for the informative Appendix C Ground Safety Valve (SSV) and Underwater Safety Valve (USV) (see Appendix C of the 2006 edition);

--- Deleted the design and rating of the high-temperature device for the informative Appendix D (see Appendix D of the 2006 edition);

--- Added normative Appendix E certificate of conformity (see Appendix E);

--- Added the Charpy V-notch impact test for the normative Appendix C welding assessment (see Appendix C).

1 Scope

This standard specifies the design, materials, welding, quality control, marking, storage and transportation requirements for drilling and drilling equipment used in oil and gas wells.

This standard applies to the following equipment.

a) ram blowout preventer;

b) gates, gate rubber cores and top seals;

c) an annular blowout preventer;

d) annular blowout preventer sealant;

e) integrated blowout preventer;

f) hydraulic connectors (wellhead devices, risers or LMRP);

g) Drilling cross and shorting of the place;

h) adapter;

i) mandrel;

j) single piece connection;

k) Clamp.

Dimensional interchangeability is limited to end and outlet connections.

Typical equipment mentioned in this standard is shown in Figures 1, 2 and 3.

This standard does not apply to field use and field tests of drill-through equipment.
