Summary

ZOD-SZDL is a complex of special fiber material and other rigid materials. It has good filling, bridge plugging and sealing function. It also can improve the stratum’s bearing pressure ability.

　　At premise of keeping normal drilling speed, ZOD-SZDL can effectively solute stratum leak and slight fissure leak compare with other additives, it has no influence in rheology behavior.

Product features

　　ZOD-SZDL makes conventional drilling fluids have strong seal and bearing properties. ZOD-SZDL can seal leaks during drilling.

　　ZOD-SZDL does not affect drilling fluids properties and drilling speed during using, and guarantee the stability of the drilling fluids.

　　ZOD-SZDL also has lubricity and can reduce the friction between the drill and the wall. ZOD-SZDL is low cost and easy to maintain.

Micro particle of ZOD-SZDL can improve the quality of mud cake and the loading capacity of formation by action of bridge blinding and film forming.
