25、l communication, resulting in costly remedial operations; lack of a hydraulic seal when utilizing cement inflatable packers. Attempts have been made to find additives that decrease cement shrinkage (shrinkage being a fundamental characteristic of Portland cement) The best solution for shrinkage thus

26、 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 case, the bulk expansion of the cement sample is simply superimposed on an inner shrinkage that will affect the porosity of t

27、he 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. This can result in the following: change in pore volume; change in pore pressure; change in sample dimensions; change in int

28、ernal 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. The change in volume of hydrates will be referred to as inner hydration shrinkage. The change in the sample dimensions will

29、 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 volume to which all volume changes are related is the volume of the slurry immediately after mixing and emplacement in the

Users of this part of ISO 10426 should be aware that further or differing requirements might be needed for individual applications. This part

31、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. This can be particularly applicable where there is innovative or developing technology. Where an alternative is offered, the

This part of ISO 10426 is based on API Technical Report 10TR 21.EN ISO 10426-5:2005 (E)4B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03 1 Scope This part of ISO 10426 provides the method

37、7-03 4 Sampling 4.1 General Samples of the neat cement or cement blend, solid and liquid additives, and mixing water are required to 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

38、materials match as closely as possible those found at the wellsite. Some commonly used sampling devices are shown in ISO 10426-2:2003, 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 exp

39、ansion under conditions of free access of water at atmospheric pressure Annular ring test 5.1 General information The annular expansion 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 a

40、mount of expanding agent, cement powder, slurry design and curing condition (pressure, temperature, time, fluid access). It should 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 gro

41、wth will tend to occur where the stress value is the lowest, i.e. in pore space or empty spaces. Therefore, the degree of cement shrinkage 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 Appa
