Test method for elastic modulus of oil well cement slurry

1 Scope

GB/T 47189-2026 is the Chinese national standard covering the stiffness of set oil well cement - a sheath that has to move with the casing as the well is pressured and heated over its life, and that cracks and loses zonal isolation if it is too rigid. First edition, in force since 1 September 2026. It was issued on 27 February 2026 and has been in force since 1 September 2026, as a first edition. The document is under the responsibility of the China Building Materials Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document outlines the experimental principles, instruments, and materials for testing the elastic modulus of oil well cement slurry, and specifies the procedures for specimen molding and preparation. Elastic modulus test and allowable difference. This document applies to the determination of the elastic modulus of cement slurry used in cementing oil and gas wells.

4.Experimental Principle Axial pressure is applied by the axial loading device of the triaxial stress testing machine, and confining pressure is applied by the confining pressure loading device. The measurement system realizes the parameter measurement. The measurement and control, data acquisition and processing system realizes the acquisition of mechanical data and the processing of stress-strain curves under test conditions, according to the... The elastic modulus of the oil well cement slurry is obtained by calculating the relationship between force and strain.
