套管柱的无缺陷固井不仅是出于安全原因，而且也是将钻井和生产成本保持在最低水平的基础。水泥作业必须满足多种条件，但其主要功能是通过确保不透水粘结并表现出足够的压缩和剪切粘结强度来防止流体和气体流过环空。各种因素都会影响密封，如泥浆清除不良、泥浆性质和钻孔条件不良。人们还认识到，水泥在水化过程中的体积变化在很大程度上导致了这些问题。体积和内部体积的变化分别产生粘结和渗透性的变化。在这项工作中，通过测量不同泥浆中的体积变化，可以更好地理解体积变化。使用了三种不同的设置，对应于三种不同的测试条件。

A flawless cementation of the casing strings is fundamental not only for safety reasons, but also to keep drilling and production costs at a minimum level.A cement job has to fulfill multiple conditions, but its main function is to prevent fluid and gas flow through the annulus by ensuring an impermeable bond and exhibiting sufficient compressive and shear bond strength.Various factors can affect the sealing, such as poor mud removal, as well as bad slurry properties and borehole conditions. It is also recognized that the volumetric changes of cement during hydration substantially contribute to these problems. Bulk and inner volumn changes produce bonding and permeability changes, respectively.In this work, volume changes were better understood by measuring them on different slurries. Three different setups that correspond to three different testing conditions were used.
