Industries du pétrole et du gaz naturel - Procédures de test des connexions pour tubes de cuvelage et de production (ISO 13679:2006)

L'ISO 13679:2002 définit les modes opératoires d'essais de vérification de la conception et les critères d'acceptation minimaux relatifs aux connexions pour tubes de cuvelage et de production employées dans les industries du pétrole et du gaz naturel. Ces essais physiques font partie d'un processus de vérification de la conception et fournissent des preuves objectives de la conformité de la connexion à l'enveloppe de charges d'essai et aux charges limites déclarées par le fabricant.
L'ISO 13679:2002 classe la sévérité des essais en quatre classes d'essais.
Elle décrit un système de codes d'identification des connexions.
Elle ne fournit pas la base statistique d'une analyse des risques.
L'ISO 13679:2002 ne traite que trois des cinq types distincts de charges primaires auxquelles sont soumises les colonnes de cuvelage et de production dans les puits: la pression du fluide (interne et/ou externe), la force axiale (traction ou compression), la flexion (flambage et/ou déviation du puits de forage) ainsi que la torsion de vissage. Elle ne traite pas des charges dues à la torsion en rotation ni des charges non axisymétriques (contact au niveau d'une surface, d'une ligne ou d'un point).
L'ISO 13679:2002 spécifie les essais devant être effectués pour déterminer la tendance au grippage, les performances en matière d'étanchéité et l'intégrité structurale des connexions pour tubes de cuvelage et de production. Les termes «tubes de cuvelage» et «tubes de production» concernent l'application de service et non le diamètre du tube.

Foreword

ISO (the International Organization for Standardization) is a 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 represented 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 drafted 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 Standard 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 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)
Introduction

This International Standard is part of a process 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 from 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 casing 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 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 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 population,

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 connections, 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 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 alternative 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 manufacturer's-supplied data

specified in Annex A and/or calculations in Annex B, tests are conducted in accordance 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 necessary 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 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 applications 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 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 are identified by the use of certain

verbal forms:
 SHALL is used to indicate that a provision is a REQUIREMENT, i.e. MANDATORY;
© ISO 2002 — All rights reserved vii
---------------------- Page: 10 ----------------------
ISO 13679:2002(E)

 SHOULD is used to indicate that a provision is a RECOMMENDATION to be used as good practice, but

is not mandatory;

 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)
Petroleum and natural 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 design verification process and provide objective evidence that the connection conforms to the

manufacturer's 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 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 and/or wellbore deviation), as well as make-up torsion. It does not address

rotation torsion and non-axisymetric (area, line or point contact) loads.

This International Standard specifies tests to be performed to determine the galling tendency, sealing

performance and structural integrity of casing and tubing connections. The words casing and tubing apply to

the service application and not to the diameter of the pipe.
