摘要： A method of controlling leak-off and reducing the concentration of polymers (and/or other materials) in filter cakes formed when oilfield treatment fluids flow through subterranean formation faces involves adding large plate-like degradable and/or non-degradable, particles to polymer or VES-viscosified oilfield treatment fluids, at concentrations of such particles that are less than that required to cover the contacted formation face with a monolayer of such particles. When these large plate-like degradable and/or non-degradable particles are included in the fluid, polymer concentrates to form filter cake only in regions on the formation face (for example fracture faces) not shielded by the large plate-like particles, and the remaining formation face is not covered by concentrated polymer. As a result, the damage due to concentration of polymer and/or other materials in the filter cake during leak-off is reduced, and subsequent clean-up of the filter cake is easier.
摘要翻译：当油田处理流体流过地下地层时形成的过滤饼中的泄漏和减少聚合物（和/或其他材料）浓度的方法包括将大的板状可降解和/或不可降解的颗粒加入到聚合物或VES-粘稠油田处理液，其浓度小于用单层这种颗粒覆盖接触的形成面所需的颗粒。当这些大的板状可降解和/或不可降解的颗粒包含在流体中时，聚合物仅在不被大板状颗粒屏蔽的形成面（例如断裂面）上的区域中集中以形成滤饼，并且剩余的形成面不被浓缩聚合物覆盖。结果，由于泄漏时滤饼中的聚合物和/或其它材料的浓度而导致的损伤减少，并且滤饼的随后的清理更容易。
