防滤失丸剂
摘要：
描述了一种防滤失丸剂包含交联聚合物凝胶、盐水以及安置在所述凝胶中的固体盐颗粒。此外，描述了一种用于降低滤失的方法，所述方法包括将选择量的防滤失丸剂泵送到井眼中，从而导致开采油－、凝析液－或气－的地层，该防滤失丸剂包含交联聚合物凝胶、盐水以及安置在所述凝胶中的固体盐颗粒。
摘要（英）：

A fluid loss pill that includes a crosslinked polymer gel, a brine, and solid salt particles disposed in said gel is described. Further, a method for reducing fluid loss that includes pumping a selected amount of a fluid loss pill into a wellbore leading to an oil-, condensate-, or gas-producing formation, the fluid loss pill including a crosslinked polymer gel, a brine, and solid salt particles disposed in said gel is described.
