25、nt mortars 3 Terms and definitions For the purposes of this part of ISO 10426, the terms and definitions given in ISO 10426-2 apply. 4 Sampling Samples of the neat cement or cement blend, solid and liquid additives, and mixing water are required to test a slurry in accordance with this part of ISO 1

26、0426. 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 well site. Additionally, the temperature of the mix water, cement or cement blends should be measured with a thermocoupl

27、e or thermometer capable of measuring temperature with an accuracy of 2 C ( 3 F). These temperatures should be recorded. Temperature-measuring devices shall be calibrated (in the case of a thermocouple) or checked (in the case of a thermometer) annually. NOTE Some commonly used sampling devices and

28、techniques can be found in ISO 10426-2. EN ISO 10426-3:2004 (E) 4B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9 NormCD - Stand 2007-035 Preparation of slurry 5.1 Preparation of conventional cement slurry Prepare the test samples in accordance with Clause 5 of ISO 10426-2:2003. The laboratory tempera

29、ture of the cement sample, additives, and mix water should be within 2 C ( 3 F) of the respective temperature anticipated at the well site. The temperature of the mixing container should approximate that of the mix water being used in the slurry design. The mixing device shall be calibrated annually

30、 to a tolerance of 200 r/min at 4 000 r/min rotational speed and 500 r/min at 12 000 r/min rotational speed. If larger slurry volumes are needed, an alternative method for slurry preparation can be found in Annex A of ISO 10426-2:2003. NOTE The density of the cement slurry can be determined by metho

31、ds found in Clause 6 of ISO 10426-2:2003. 5.2 Preparation of speciality cement slurries Cementing operations in deepwater environments may require the use of speciality cements, including foamed cement or microsphere-containing cement formulations. The preparation and testing of these speciality cem

32、ent formulations should be undertaken using the best available methods or methods mutually agreed upon by the service provider and the end user. 6 Strength tests for deepwater well cements 6.1 General information The strength development of cement used in a deepwater cementation can be influenced by

33、 many factors, including heat of hydration, casing/wellbore size, final slurry location (annulus or shoe track), and initial slurry temperature. Given the number of variables contributing to the rate of strength development in a deepwater well, the temperature and pressure schedule should be determi

34、ned by means of numerical heat transfer simulation or by field measurement from an offset well(s). In this way, the test schedule can reflect as closely as possible the actual temperature and pressure profiles found after placement. The preferred method for determining the strength of deepwater ceme

35、nt is by means of a non-destructive sonic test method. Non-destructive sonic testing of a cement slurry may be conducted by methods provided in Clause 8 of ISO 10426-2:2003. Speciality cement systems, as described in 5.2, may employ destructive testing to determine compressive strength. The energy p

36、roduced by hydrating cement generates a considerable amount of heat. In a large annulus typically found in the top-hole section of a deepwater well, it is expected that the hydration exotherm (thermal mass effect) may raise the temperature within the annulus significantly. As such, a general guideli

37、ne is to conduct the strength test at a low curing temperature for only as long as the cement remains unset. Once initial strength of 345 kPa (50 psi) is reached, the curing temperature may be raised to reflect the hydration exotherm. 6.2 Sampling methods The sampling methods for strength testing ar

38、e provided in Clause 4. 6.3 Preparation of slurry The slurry shall be prepared in accordance with Clause 5. EN ISO 10426-3:2004 (E) 5B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9 NormCD - Stand 2007-036.4 Non-destructive sonic testing 6.4.1 Apparatus for non-destructive testing CAUTION Care should

39、be exercised to ensure that excess condensation caused by chilling the test apparatus does not cause electrical or other damage, which may create safety hazards. The apparatus transmits a sonic signal through the cement, which can be correlated to cement properties such as the time and extent of str

40、ength development. In order to simulate conditions common to deepwater cementing, the apparatus shall possess sufficient cooling capacity to perform strength testing at temperatures anticipated in the wellbore. Excessive free fluid can impair the accuracy of the non-destructive sonic test. Free flui

41、d in a slurry can inhibit contact with the top cell cover and affect the sonic signal being transmitted through the cement. Free fluid is determined according to the method provided in Clause 9. The test initiation temperature of the slurry should reflect as closely as possible the temperature condi

42、tions found during the field mixing operation. 6.4.1.1 Curing cell, in which the slurry temperature and pressure can be controlled according to the appropriate schedule. A pressure vessel suitable for curing samples at a test temperature anticipated on the well and capable of maintaining pressure sh

43、all be used. As pressure is known to have an effect on strength development, the pressure appropriate for the placement conditions should be used for testing. Do not exceed the pressure limitations of the apparatus. 6.4.1.2 Temperature-measuring system, in accordance with 8.2.1 of ISO 10426-2:2003.

44、6.4.1.3 Sonic signal-measuring system, in accordance with 8.2.2 of ISO 10426-2:2003. 6.4.2 Procedure Operate the apparatus according to the manufacturers instructions. To better simulate the temperature profile found in a deepwater well, ramp the curing cell temperature from surface mixing temperatu

45、re to the desired test temperature according to a specific schedule determined by thermal simulation. Alternatively, chill the curing cell to the desired test temperature or below, before the slurry is placed into the curing cell. The slurry may also be conditioned in accordance with 6.4.3 or 6.4.4.

46、 The test period begins with the recording of sonic data and the application of pressure and continues until the test is terminated. Begin recording the sonic data within 5 min after the application of pressure. The pressure ramp should simulate the pressure conditions to which the cement shall be e

47、xposed during placement. 6.4.3 Conditioning of consistometer for atmospheric pressure testing After the slurry has been prepared, place it into an atmospheric consistometer slurry container that has been chilled to the desired test temperature. At user discretion, the temperature of the slurry conta

48、iner and/or the cooling fluid within the atmospheric consistometer may be lower than the bottomhole test temperature in order to promote a more rapid cool-down. Place the cup into a chilled atmospheric consistometer and condition for 20 min. After 20 min, verify the temperature, remove the paddle fr

49、om the cup and stir the slurry briskly with a spatula to ensure a uniform slurry. If the cement slurry has not reached the desired test temperature, continue conditioning until the desired test temperature has been reached. It is permissible for the sample to be further conditioned for a period of time to sim
