The work of preparing I

26、nternational 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

27、 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 tech

28、nical 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. In exceptional ci

29、rcumstances, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report

30、is entirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or useful. 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 id

31、entifying any or all such patent rights. ISO/TR 10400 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.This first edition of ISO/TR 10400 cancels and r

32、eplaces ISO 10400:1993, which has been technically revised. IntroductionPerformance design of tubulars for the petroleum and natural gas industries, whether it is formulated by deterministic or probabilistic calculations, compares anticipated loads to which the tubular may be subjected to the antici

33、pated resistance of the tubular to each load. Either or both the load and resistance may be modified by a design factor. Both deterministic and probabilistic (synthesis method) approaches to performance properties are addressed in this Technical Report. The deterministic approach uses specific geome

34、tric and material property values to calculate a single performance property value. The synthesis method treats the same variables as random and thus arrives at a statistical distribution of a performance property. A performance distribution in combination with a defined lower percentile determines

35、the final design equation. Both the well design process itself and the definition of anticipated loads are currently outside the scope of standardization for the petroleum and natural gas industries. Neither of these aspects is addressed in this Technical Report. Rather, this text serves to identify

36、 useful equations for obtaining the resistance of a tubular to specified loads, independent of their origin. This Technical Report provides limit state equations (see annexes) which are useful for determining the resistance of an individual sample whose geometry and material properties are given, an

37、d design equations which are useful for well design based on conservative geometric and material parameters. Whenever possible, decisions on specific constants to use in a design equation are left to the discretion of the reader. TECHNICAL REPORT ISO/TR 10400:2007(E) ISO 2007 All rights reserved 1Pe

38、troleum and natural gas industries Equations and calculations for the properties of casing, tubing, drill pipe and line pipe used as casing or tubing 1 Scope This Technical Report illustrates the equations and templates necessary to calculate the various pipe properties given in International Standa

39、rds, including pipe performance properties, such as axial strength, internal pressure resistance and collapse resistance, minimum physical properties, product assembly force (torque), product test pressures, critical product dimensions related to testing criteria, critical dimensions of testing equi

40、pment, and critical dimensions of test samples. For equations related to performance properties, extensive background information is also provided regarding their development and use. Equations presented here are intended for use with pipe manufactured in accordance with ISO 11960 or API 5CT, ISO 11

41、961 or API 5D, and ISO 3183 or API 5L, as applicable. These equations and templates may be extended to other pipe with due caution. Pipe cold-worked during production is included in the scope of this Technical Report (e.g. cold rotary straightened pipe). Pipe modified by cold working after productio

42、n, such as expandable tubulars and coiled tubing, is beyond the scope of this Technical Report. Application of performance property equations in this Technical Report to line pipe and other pipe is restricted to their use as casing/tubing in a well or laboratory test, and requires due caution to mat

43、ch the heat-treat process, straightening process, yield strength, etc., with the closest appropriate casing/tubing product. Similar caution should be exercised when using the performance equations for drill pipe. This Technical Report and the equations contained herein relate the input pipe manufact

44、uring parameters in ISO 11960 or API 5CT, ISO 11961 or API 5D, and ISO 3183 or API 5L to expected pipe performance. The design equations in this Technical Report are not to be understood as a manufacturing warrantee. Manufacturers are typically licensed to produce tubular products in accordance with

45、 manufacturing specifications which control the dimensions and physical properties of their product. Design equations, on the other hand, are a reference point for users to characterize tubular performance and begin their own well design or research of pipe input properties. This Technical Report is

46、 not a design code. It only provides equations and templates for calculating the properties of tubulars intended for use in downhole applications. This Technical Report does not provide any guidance about loads that can be encountered by tubulars or about safety margins needed for acceptable design.

47、 Users are responsible for defining appropriate design loads and selecting adequate safety factors to develop safe and efficient designs. The design loads and safety factors will likely be selected based on historical practice, local regulatory requirements, and specific well conditions. API Technic
