Abstract: The brittleness and poor resistance to external load of oil well cement hinder the development of oil and gas wells. In order to overcome these defects, emulsion powder or rubber and its mixed combination are used to modify oil well cement. The conventional properties, mechanical properties and scanning electron microscope (SEM) images of modified cement were analyzed. Compared with latex powder mixed cement and rubber mixed cement, when three mixture combinations are used, the water loss rate, flexural strength, impact strength and elasticity of cement slurry are significantly improved
