Capillary crystallization type self-repairing agent for oil well cement as well as preparation and application thereof
The invention discloses a capillary crystalline self-repairing agent for oil well cement. The capillary crystalline self-repairing agent for the oil well cement is cement of which the surface is grafted with organosilane. The invention further discloses a preparation method and application of the oil well cement capillary crystalline type self-repairing agent. According to the oil well cement capillary crystalline type self-repairing agent, the proportion of unhydrated cement in set cement is increased, and when cracks appear in the later period, the cracks are effectively repaired by means of secondary hydration of the unhydrated cement.
本发明公开了一种油井水泥渗透结晶型自修复剂，所述油井水泥渗透结晶型自修复剂为表面接枝有机硅烷的水泥。本发明还公开上述油井水泥渗透结晶型自修复剂的制备方法和应用。本发明提供的油井水泥渗透结晶型自修复剂，提高水泥石中未水化水泥的比例，在后期裂缝出现时，借助未水化水泥的二次水化，有效的修补裂缝。
