High-Performance Oil-Based Mud Rheology Modifier & Thinner from China Suppliers and Factory - UBDrill-261
Product Introduction
UBDrill-261 is a kind of OBM thinner and then diluting them with a certain amount of white oil while using. During the drilling process, fine drill cuttings particles will disperse and accumulate in the drilling fluid. Excessive solid phase can rapidly lead to an increase in rheological parameters, including static and dynamic shear.
An increase in rheological parameters will reduce drilling speed and increase pump pressure until it exceeds the fracture pressure of the formation.
The addition of UBDrill-261 diluents to oil-based mud effectively solves the problem of increased rheological parameters caused by ultrafine drilling cuttings in the absence of efficient solid control equipment.
