High-Performance Oil-Based Mud Thinner & Rheology Modifier 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.

Frequently Asked Questions (FAQ)
What is UBDrill-261?
UBDrill-261 is an oil-based mud (OBM) thinner designed to be diluted with a specific amount of white oil during use. It effectively solves the problem of increased rheological parameters caused by ultrafine drilling cuttings.
What are the primary applications of UBDrill-261?
It functions as a thinner to reduce drilling fluid viscosity and is specifically suitable for use in high-temperature and high-pressure (HTHP) oil wells.
What is the thermal stability limit of UBDrill-261?
UBDrill-261 exhibits excellent thermal stability and remains stable at temperatures up to 400 °F.
What is the recommended dosage for application?
The recommended low-density dosage is 0.1% to 0.25% (v/w), and the high-density dosage is 0.5% to 1%. A pilot test is always required to determine the optimal dosage.
How should UBDrill-261 be packaged and stored?
It is packaged in 55-GAL drums. It should be stored in a dry, well-ventilated area with the container closed, away from heat, sparks, flames, and incompatible materials.
