It can effectively resist corrosion from downhole compounds. The LubeSeal brand 101EU deep water high-temperature downhole tool lubricant is formulated with LIQUILON\uff0c which greatly enhances its lubrication and extreme pressure performance. LIQUILON is not affected by acids\uff0c corrosives\uff0c downhole compounds and hydrocarbons containing gasoline and solvents. The LubeSeal brand 101EU deep water high-temperature downhole tool lubricant is an inert substance and has thermal stability. The film-forming property of the LubeSeal brand 101EU type deep water high-temperature downhole tool lubricant eliminates wear\uff0c effectively prevents rust and corrosion\uff0c and avoids contact between metal surfaces\uff0c thereby significantly reducing the operating temperature of the equipment. In many field application cases\uff0c the power output of the drive power supply has been reduced to a certain extent. The LubeSeal brand 101EU deep water high-temperature downhole tool lubricant can provide immediate lubrication for key equipment areas when the equipment starts. The LubeSeal 101EU deepwater high-temperature downhole tool lubricant is recommended for use in O-rings, sealing joints, gaskets, packer plugs, and other downhole tool accessories to prevent drying out, cracking, and contamination by downhole compounds. The LubeSeal 101EU deepwater high-temperature downhole tool lubricant is also recommended for lubricating steel wire operation equipment and other various downhole tools that are extremely important for corrosion resistance and wear resistance. The LubeSeal 101EU deepwater high-temperature downhole tool lubricant makes the disassembly and removal operations of downhole tools affected by harmful downhole compounds convenient and fast.
