Summary
OBF-LUBE WB is an environmentally friendly water-based lubricant based on polymeric alcohol, which has good shale inhibition, lubricity, high temperature stability and anti-pollution properties. It is non-toxic, easily biodegradable and has little damage to the oil formation, and is widely used in oilfield drilling operations with good effect.
Features
Improving the rheology of drilling fluids and increasing the solid phase capacity limit by 10 to 20%.
Improvement of organic treating agent heat stabilizer, improving the temperature resistance of the treating agent by 20~30℃.
Strong anti-collapse ability, regular well diameter, average borehole enlargement rate ≤ 5%.
Borehole mud cake with properties similar to oil-based drilling fluid mud cake, with excellent lubricity.
Improving filtrate viscosity, molecular colloid blocking and reducing oil-water interfacial tension to protect the reservoir.
Preventing mud pack of drill bit, reducing complex accidents downhole and improving mechanical drilling speed.
LC50>30000mg/L, protect the environment.
