Abstract
The conventional cement can damage reservoirs in sealing profile water plugging and reservoir recreating,so as to influence the acid stimulation,but the magnesium oxychloride cement can fix them very well.In this paper,the effect of magnesium oxychloride cement stone compressive strength in hot water is studied by XRD and SEMEDX.The results show that the strength decreases with longer time and higher curing temperature,the component and form of hydration products have negative effect on the strength,and the best ratio is MgO:MgCl2:H2O= 8:1:16 in normal temperature.
