26、 worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represente
27、d on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are draf
28、ted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Sta
29、ndard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13679 was prepared
30、by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 5, Casing, tubing and drill pipe. -,-,- ISO 13679:2002(E) ISO 2002 All rights reserved vii Introduction This International Standard is part of a pro
31、cess to provide reliable tubing and casing connections for the oil and natural gas industry which are fit for purpose. It has been developed based on improvements to API Recommended Practice 5C5 and proprietary test procedures, with input from leading users, manufacturers and testing consultants fro
32、m around the world. This International Standard represents the knowledge of many years of testing and qualification experiences. The validation of connection test load envelope and failure limit loads is relevant to design of tubing and casing for the oil and natural gas industries. Tubing and casin
33、g are subject to loads which include internal pressure, external pressure, axial tension, axial compression, bending, torsion, transverse forces and temperature changes. The magnitude and combination of these loads result in various pipe body and connection failure modes. Although pipe body test and
34、 limit loads are well understood in general, the same cannot be stated for the connection. These failure modes and loads are generally different and often less than that of the pipe. Consequently experimental validation is required. Well design matches the test and limit loads of both the connection
35、 and pipe to the well conditions to provide load capacities with suitable reliability. The validation of test and limit loads requires testing at the extremes of performance parameters to these defined loads. Testing at the extremes of the performance parameters assures that the production populatio
36、n, which falls within these limits, will meet or exceed the performance of the test population. Thread connection performance parameters include dimensional tolerances, mechanical properties, surface treatment, make-up torque and the type and amount of thread compound. For typical proprietary connec
37、tions, worst-case tolerances are known and defined in this International Standard. For other connections design analysis is required to define worst-case tolerance combinations. Users of this International Standard should be aware that further or differing requirements might be needed for individual
38、 applications. This International Standard is not intended to inhibit a vendor from offering, or a purchaser from accepting, alternate equipment or engineering solutions for the individual application. This may be particularly applicable when there is innovative or developing technology. Where an al
39、ternative is offered, the vendor should identify any variations from this International Standard and provide details. This International Standard consists of the following major parts. Based on manufacturers-supplied data specified in Annex A and/or calculations in Annex B, tests are conducted in ac
40、cordance with Clauses 4 to 8 and reported on the data forms given in Annex C. Annex D lists all the information that is to be provided in the full report whereas Annex E lists the information that is to be provided in a summary test report. This summary test report lists the minimum information nece
41、ssary to fully specify the connection tested and its preparation is intended for broader distribution. Annex F gives an example of a load frame calibration. Annex G gives considerations for possible connection product line qualification. Annex H provides guidelines for supplemental tests, which may
42、be required for special applications. Annex I gives the design rationale for this International Standard. Annex J gives requirements for connections that contain both a metal-to-metal seal and a resilient seal which are tested separately. Supplementary tests may be appropriate for specific applicati
43、ons that are not evaluated by the tests herein. The user and manufacturer should discuss well applications and limitations of the connection being considered. Representatives of users and/or other third party personnel are encouraged to monitor the tests. ISO 13679 covers the testing of connections
44、for the most commonly encountered well conditions. Not all possible service scenarios are included. For example, the presence of a corrosive fluid, which may influence the service performance of a connection, is not considered. This International Standard includes provisions of various nature. These
45、 are identified by the use of certain verbal forms: SHALL is used to indicate that a provision is a REQUIREMENT, i.e. MANDATORY; -,-,- ISO 13679:2002(E) viii ISO 2002 All rights reserved SHOULD is used to indicate that a provision is a RECOMMENDATION to be used as good practice, but is not mandatory
46、; MAY is used to indicate that a provision is OPTIONAL, i.e. indicates a course of action permissible within the limits of the document; CAN is used to indicate statements of POSSIBILITY and CAPABILITY. -,-,- INTERNATIONAL STANDARD ISO 13679:2002(E) ISO 2002 All rights reserved 1 Petroleum and natur
47、al gas industries Procedures for testing casing and tubing connections 1 Scope This International Standard establishes minimum design verification testing procedures and acceptance criteria for casing and tubing connections for the oil and natural gas industries. These physical tests are part of a d
48、esign verification process and provide objective evidence that the connection conforms to the manufacturers claimed test load envelope and limit loads. It categorizes test severity into four test classes. It describes a system of identification codes for connections. This International Standard does
49、 not provide the statistical basis for risk analysis. This International Standard addresses only three of the five distinct types of primary loads to which casing and tubing strings are subjected in wells: fluid pressure (internal and/or external), axial force (tension or compression), bending (buckling a
