22、dization) 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
23、 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 Stan
24、dards 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 Int
25、ernational 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 10426
26、-5 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 3, Drilling and completion fluids, and well cements. ISO 10426 consists of the following parts, under the general title Petroleum an

28、nsion of well cement formulations at atmospheric pressure EN ISO 10426-5:2005 vIntroduction Dimensional changes in oil- and gas-well cements after placement, phenomena often referred to as shrinkage, (when the dimensional change corresponds to a decrease in cement volume) have often been used to exp
29、lain various wellbore phenomena including a microannulus, leading to a bad bond as demonstrated by the bond log; interzonal communication, resulting in costly remedial operations; lack of a hydraulic seal when utilizing cement inflatable packers. Attempts have been made to find additives that decrea
30、se cement shrinkage (shrinkage being a fundamental characteristic of Portland cement) The best solution for shrinkage thus far has been the identification of additives that favour the expansion of the cement. However, even if cement expands dimensionally, it will still shrink internally. In this cas
31、e, the bulk expansion of the cement sample is simply superimposed on an inner shrinkage that will affect the porosity of the sample. Shrinkage and expansion in cement result from the formation of hydration products having a density different from the compounded density of the reaction components. Th
32、is can result in the following: change in pore volume; change in pore pressure; change in sample dimensions; change in internal stress. In a closed cell with a non-deformable boundary, the volume of hydrates produced during the chemical reaction is less than the volume of dry compounds plus water. T
33、he change in volume of hydrates will be referred to as inner hydration shrinkage. The change in the sample dimensions will be referred to as bulk shrinkage or expansion. Bulk shrinkage and expansion of cement refer to the result of the measurement of linear dimensional change or volume change. The v
34、olume to which all volume changes are related is the volume of the slurry immediately after mixing and emplacement in the experimental equipment. In this part of ISO 10426, units are given as SI, and where practical, U.S. Customary units are included in brackets for information. Users of this part o
35、f ISO 10426 should be aware that further or differing requirements might be needed for individual applications. This part of ISO 10426 is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. Th
36、is can be particularly applicable where 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 part of ISO 10426 is based on API Technical Report 10TR 21 .

37、blank1Petroleum and natural gas industries Cements and materials for well cementing Part 5: Determination of shrinkage and expansion of well cement formulations at atmospheric pressure 1 Scope This part of ISO 10426 provides the methods for the testing of well cement formulations to determine the di
38、mension changes during the curing process (cement hydration) at atmospheric pressure only. This is a base document, because under real well cementing conditions shrinkage and expansion take place under pressure and different boundary conditions. 2 Normative references The following referenced docume

42、 test a slurry according to this part of ISO 10426. Accordingly, the best available sampling technology should be employed to ensure the laboratory test conditions and materials match as closely as possible those found at the wellsite. Some commonly used sampling devices are shown in ISO 10426-2:200
43、3, Figure 1. 4.2 Method Applicable sampling techniques for the fluids and materials used are specified in ISO 10426-2:2003, Clause 4. 5 Determination of shrinkage or expansion under conditions of free access of water at atmospheric pressure Annular ring test 5.1 General information The annular expan
44、sion mould is a device suitable for measuring only the linear bulk shrinkage or expansion properties of a cement formulation. The magnitude of expansion depends on the amount of expanding agent, cement powder, slurry design and curing condition (pressure, temperature, time, fluid access). It should
45、be noted that expansion is strongly affected by boundary conditions. The chemical process of mineral growth is strongly controlled by the state of stress and mineral growth will tend to occur where the stress value is the lowest, i.e. in pore space or empty spaces. Therefore, the degree of cement sh
46、rinkage and expansion is dependent on a number of conditions, not all of which can be uniquely defined. The test does not represent fully the annulus of a well. 5.2 Apparatus 5.2.1 Mould 5.2.1.1 General Use corrosion-resistant material (e.g. stainless steel). The outer diameter (OD) of the inner rin
