摘要：
Sealant compositions comprising a colloidal stabilized latex and methods of using the same to service a wellbore are provided. The sealant compositions may include; an aliphatic conjugated diene monomer; an additional monomer comprising a non-aromatic unsaturated mono-or di- carboxylic ester monomer, an aromatic unsaturated monomer, a nitrogen-containing monomer, or combinations thereof; and a protective colloid. The foregoing sealant composition may be displaced into the wellbore to isolate the subterranean formation from a portion of the wellbore, to support a conduit in the wellbore, to plug a void or crack in the conduit, to plug a void or crack in a cement sheath disposed in an annulus of the wellbore, to plug an opening between the cement sheath and the conduit, or combinations thereof. The colloidally stabilized latex remains substantially stable when exposed to salt, which may be present in the wellbore and/or in the sealant composition itself.
摘要（中）：
提供了包含胶体稳定的胶乳的密封剂组合物及其使用以维护井眼的方法。 密封剂组合物可包括： 脂族共轭二烯单体; 包含非芳族不饱和单酯或二羧酸酯单体，芳族不饱和单体，含氮单体或其组合的另外的单体; 和保护胶体。 上述密封剂组合物可以移动到井筒中以将地层与井筒的一部分隔离，以支撑井眼中的导管，以堵塞管道中的空隙或裂缝，以堵塞水泥鞘中的空隙或裂缝 设置在井筒的环形空间中，以堵塞水泥护套和导管之间的开口，或其组合。 当暴露于盐时，胶体稳定的胶乳保持基本稳定，盐可存在于井筒和/或密封剂组合物本身中。
