Product Detail

1. Summary

OBF-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, OBF-SZDL can effectively solute stratum leak and slight fissure leak compare with other additives,it has no influence in rheology behavior.

2 .Product features

OBF-SZDL makes conventional drilling fluids have strong seal and bearing properties. OBF-SZDLcan sealleaks during drilling.

OBF-SZDL does not affect drillingfluidsproperties and drilling speed during using, and guarantee the stability of the drillingfluids.

OBF-SZDLalso has lubricity and can reduce the friction between the drill and the wall. OBF-SZDLis low cost and easy to maintain.

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