Description

General
FL (11L/12S) fluid loss control agent is a new type of cross linked polymer. It attaches to cement particle surface through heavy polymer, and forms cross linked network in the cement slurry. When there is certain pressure difference between cement slurry and the formation, it forms tight high molecular membrane at the contact to make sure cement slurry has low filtration rate. This product has good fluid loss control ability and API fluid loss rate is less than 50ml. It has good flow-ability, easily pumping, good thickening property, stable initial thickness, fast thickening transitional time, high stability. It does not separate or settle down, and has no retarding function or unfavorable impact on strength development of set cement.
