Weighted fluid loss control pellets for well completion and workover operations
A novel completion fluid composition for fluid loss control during completion and workover operations on a wellbore penetrating a formation is disclosed. In particular, the composition is a weighted brine fluid having a polymetaphosphate composition, a biopolymer suspending agent, and a fluid loss control additive. These novel compositions provide a means to temporarily seal a wellbore in communication with the formation, enabling completion or workover operations, after which the composition can be removed by contact with an acidic composition.
公开了用于在穿透地层的井筒上进行完井和修井操作期间的流体损失控制的新型完井液组合物。特别地，该组合物是具有聚偏磷酸盐组合物、生物聚合物悬浮剂和流体损失控制添加剂的加重的盐水流体。这些新型组合物提供了暂时密封与地层连通的井筒的手段，使得能够进行完井或修井操作，之后可以通过与酸性组合物接触来除去组合物。
