The work of preparing International Standards is normally carried out through ISO technical committ

26、ees. 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 Int

27、ernational 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

28、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 s

ISO 10427-1:2001, 3.11 4 Methods for estimating centralizer placement 4.1 General The equa

45、tions presented below are based on certain assumptions and are considered sufficiently accurate for general use. More specific calculations based on complete wellbore data may be available but are beyond the scope of this document. There is no recommendation or requirement for a specific standoff ra

46、tio for casing centralization. The standoff ratio of 67 % is used in the specification for the purpose of setting a minimum standard for performance of casing bow-spring centralizers only. This number is used only in the specifications for bow-spring type centralizers and deals with the minimum forc

47、e for each size of centralizer at that standoff. The 67 % standoff ratio is not intended to represent the minimum acceptable amount of standoff required to obtain successful centralization of the casing. The user is encouraged to apply the standoff ratio required for specific well conditions based o

48、n well requirements and sound engineering judgement. Even a minor change in inclination and/or azimuth, with the string of casing hanging below it, materially affects the standoff and the requirements for centralizer placement. ENISO104272:2004ISO 10427-2:2004(E) 4 The lateral load (force) on a centralizer is composed of two components. The first is the weight component of the section of pipe supported by the centralizer, and the second is the tension co
