It is disconnected to occur.The importance of cementing concrete ring integrality is increasingly paid high attention to.By it is substantial amounts of research show, cement sheath it is complete
Whole property depends on compression strength and becomes sexuality.Under the external load function of underground, cement sheath there may be two kinds of destructions of form, one
It is that cement sheath will produce strength failure when external applied load exceedes the strength degree of Behavior of Hardened Cement Paste；Two is the cement under applied external force
Occur micro-crack or volume contraction inside ring, cause seal failure.
In order to improve the integrality of cement sheath, oil-well cement starts to consider the intensity of Behavior of Hardened Cement Paste simultaneously when designing and becomes performance
Two indexs of aspect of power, one of them important newly-increased index is the elastic modelling quantity of Behavior of Hardened Cement Paste.Elastic modelling quantity is also known as Young mould
Amount, is a kind of mode for characterizing object elastic deformation complexity, and it is defined as being the ratio between stress and strain.The elasticity of Behavior of Hardened Cement Paste
Modulus value is lower, and the toughness for representing material is better, and fragility is lower, is conducive to improving the integrality of cement sheath.Therefore, exploitation has
The cement of low elastic modulus is the important research direction of current cementing concrete.
The detection method of elastic modelling quantity has two kinds, and one kind is that material detects elastic mould value under the conditions of simple stress, this
The method of kind is applied to most of materials, and detection method is simple, can be completed by general compression testing machine.Second is three axles
Detected under stress condition, be mainly used in the mechanics properties testing of rock.Cement sheath stress in the earth formation is close with rock,
Therefore the detection of Behavior of Hardened Cement Paste elastic modelling quantity is carried out using triaxial stress environment and obtains approval extensively.
So-called triaxial stress is material in addition to active force is applied up and down, need to apply active force, simulation rock simultaneously in surrounding
The mechanical state of surrounding stress in the earth formation, accordingly, it would be desirable to special mechanics testing equipment is detected.The rock commonly used at present
Triaxiality stressh machine is the ideal equipment for detecting Behavior of Hardened Cement Paste elastic modelling quantity, but, such apparatus expensive, purposes scope is small,
Cement properties detection field is promoted has very big difficulty.
