Particle-size properties of oilwell cements
AbstractParticle size distribution (PSD) was measured by a sedimentation method for 27 oilwell cements that met API physical and compositional specifications. Cumulative mass distribution (CMD) curves had very similar shapes when plotted as a function of particle diameter from 0.4 to 100-μm. Particles <8-μm diameter accounted for from 19 to 40% of the total mass, depending upon the class of cement, and for from 63 to 76% of the total surface area. Detection of multimodal distributions was not possible because of the magnitude of the experimental error. A very high linear correlation was found between Blaine fineness (190 to 440 m2/kg) and surface area calculated from CMD.
