Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB 10238-2005 "oil well cement."
The main changes compared to the Standard and GB 10238-2005 are as follows.
--- This standard is mandatory nature of the change recommended;
--- Deleted E-class, F-class two-level oil well cement (2005 Version 4.1.1);
--- Temperature for temperature measurement and control system allows deviation and pressure measurement system requirements, and has been modified (see Chapter 8, 9
Chapter, Chapter 10, 2005 edition of Chapter 8, Chapter 9, Chapter 10);
--- On timers and temperature measurement system calibration frequency required changes (see Chapter 7, Chapter 8, Chapter 9, Chapter 10, 2005
Version of Chapter 7, Chapter 8, Chapter 9, Chapter 10);
--- Compressive strength test mode from the original side of 50.8mm to 50mm or 2in (see 9.1.1.1,2005 version 9.1.1);
The performance indicators --- pressure thickening device used in hydrocarbon oil change (see 10.1,2005 version 10.1).
This standard uses redrafted Law Amendment uses ISO 10426-1.2009 "cementing oil well cement and material specifications."
This standard and ISO 10426-1.2009 compared to more adjustments in the structure, are given in Appendix A of this standard and ISO 10426-1.

This standard and ISO 10426-1.2009 compared to the existence of technical differences, these differences involve the provision has passed the gap in the outside margin
Vertical single-line position (|) be marked Appendix B gives a list of corresponding technical differences and their causes.
This standard also made the following editorial changes.
--- Remove the ISO 10426-1.2009 Foreword and Introduction;
--- Remove the ISO 10426-1. Appendix A 2009's "thermocouple temperature measurement system and the controller calibration procedure";
--- Remove the ISO 10426-1. Appendix B 2009 "License holders use API monogram."
