23、odies (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 be represented on that committee. International organizati

24、ons, 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 Standards are drafted in accordance with the rules given in the

25、 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 International Standard requires approval by at least 75 % of t

26、he 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 10426-4 was prepared by Technical Committee ISO/TC 67, Materials

27、, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 3, Drilling and completion fluids, and well cements.

This part of ISO 10426 is not intended to inhibit a vendor from offering, or the purchaser

30、from accepting, alternative equipment or engineering solutions for the individual application. This may 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 provi

31、de details. Cements or cement blends used for foamed cement slurry preparation at atmospheric pressure should be fit for purpose. Such cements could include well cements of ISO Classes, high alumina cement, or other speciality cements. The cements and blending materials should conform to appropriate

32、 standards. Where International Standards do not exist, conformance with other appropriate standards should be made. In this part of ISO 10426, where practical, U.S. Customary units are included in brackets for information. ENISO104264:2004blank 4002:462401OSINEINTENRATIONAL TSANDADR IS-62401 O4:(40

For dated references, only the edition cited applies. For undated references, the latest edition of the ref

35、erenced document (including any amendments) applies.

36、ixing are required to test a foamed cement slurry in accordance with this part of ISO 10426. Accordingly, the best available sampling technology should be employed to ensure the test materials match as closely as possible those found at the well site. 3.2 Method Applicable sampling techniques for th

37、e fluids and materials used in foamed cementing operations can be found in ISO 10426-2:2003, Clause 4. If required, the temperatures of the mix water, cement or cement blends, and liquid additives may be measured with a thermocouple or thermometer capable of measuring temperature with an accuracy of

38、 2 C ( 3,5 F). These temperatures should be recorded. Temperature- measuring devices shall be calibrated (in the case of a thermocouple) or checked for accuracy (in the case of a thermometer) annually. 4 Slurry calculations 4.1 Calculation of base cement slurry composition with and without surfactan

39、t(s) The final base cement slurry for preparing a foamed cement slurry contains surfactant(s), which cannot be added to the base cement slurry for initial mixing. This requires calculation of the relative mass percentage (mass fraction) of the surfactant(s) in the foamed cement slurry. This is done

40、by taking the total mass of the ENISO104264:2004ISO 10426-4:2004(E) 2 I SO 4002 All irthgs ersedevrsurfactant(s) and dividing by the total mass of the base cement slurry. (For these calculations, additives are considered those materials added to the cement that do not result in foaming the system.)

41、The mass fraction (percentage) of surfactant(s) can be calculated by: w s= m s /(m c+ m a+ m s+ m w ) 100 (1) where w sis the mass fraction of surfactant(s), expressed as a percent; m sis the mass of surfactant(s), expressed in grams; m cis the mass of cement, expressed in grams; m ais the mass of a

42、dditive(s), expressed in grams; m wis the mass of water, expressed in grams. If desired, the base cement slurry density without surfactant ( bwos ) can be calculated, in grams per cubic centimetre, by: caw bwos caw mmm VVV + = +(2) where m cis the mass of cement, expressed in grams; m ais the mass o

43、f additive(s), expressed in grams; m wis the mass of water, expressed in grams; V cis the absolute volume of cement, expressed in cubic centimetres; V ais the absolute volume of additive(s), expressed in cubic centimetres; V wis the volume of water, expressed in cubic centimetres. 4.2 Determination

44、of slurry volume and mass 4.2.1 Slurry volume 4.2.1.1 General Determine the volume of unfoamed base cement slurry to be used. The total volume of unfoamed base cement slurry shall include the volume of surfactant(s) to be added to the base cement slurry. The surfactant(s) is(are) added after the ini

45、tial mixing of the base cement slurry. The volume of unfoamed base cement slurry with surfactants to be placed in the blending container can be calculated by one of two methods (see 4.2.1.2 and 4.2.1.3).

46、n it is desired to foam a slurry with a specific volume fraction of gas per volume of slurry (foam quality), the resultant density of the foamed cement slurry must be determined. This can be calculated by: g fs ufss 100 100 = (3) where fsis the density of the foamed cement slurry, expressed in kilog

47、rams per cubic metre (pounds-mass per gallon); gis the volume fraction of gas in the final foamed cement slurry, expressed as a percent; ufssis the density of the unfoamed base cement slurry with surfactant(s), expressed in kilograms per cubic metre (pounds-mass per gallon). 4.2.1.3 Known foamed cem
