24、 reservedForeword 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

25、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 al

26、l 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

27、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 res

31、r natural gas-producing well. The objective of this part of ISO 13503 is to provide a standard procedure for measuring the viscous properties of single-phase, non-particulate-laden completion fluids. These fluids are viscosified brines, gravel-pack carrier fluids, and fracturing fluids. These fluids

32、 can be either crosslinked or non-crosslinked (aqueous, hydrocarbon- or acid-based). An optional shear-history simulation procedure is provided for fluids that are potentially shear-sensitive. This procedure is designed to simulate the shearing effects experienced by a fluid in surface apparatus and

33、 during the time it is being conveyed down the welbore. Shear-history simulation is most often used during the development of new fracturing fluids to characterize their sensitivity to shear. These standard procedures were compiled on the basis of several years of comparative testing, debate, discus

34、sion, and continued research by the industry. This standard procedure is largely based on API RP 39, third edition, May 1998 1. In this part of ISO 13503, where practical, U.S. Customary units are included in parentheses for convenience. API Recommended Practice 13M / ISO 13503-1vINTERNATIONAL STAND
