Research on the influence of polyanionic cellulose on the microstructure and properties of oil well cement

Drilling fluid additive is an important factor of contamination between cement paste and drilling fluid, in which PAC is the most significant one. This work investigated the effects of PAC on the hydration process and properties of cement by using X-ray diffraction (XRD), Different scanning thermal analyzer (DSC), Fourier transform infrared spectrometer (FTIR) and Zeta-potential. Based on the results of Environment Scanning Electron Microscopy...
