  • In Donghai Oil and Gas Field, more and more extended reach wells, high angle deviated wells and multilateral horizontal wells have been drilled in recent years. During the drilling operations, high torque and wear-and-tear experienced by the drill pipes and the casing strings have impacted on the safety and the efficiency of the drilling operations. A highly efficient anti-wear friction reducer, ARDR LUBE-100 was found, after extensive investigation and experiments, to be effective in dealing with the problems aforementioned. ARDR LUBE-100 is a compound of organic anions and organic metals, and is a product of anti-wear materials such as alcohols and esters through esterification reaction or condensation reaction at high temperatures. Organic metal ions are generated in intermediate synthesis reaction, and anti-wear inert ions are added into the reactants. ARDR LUBE-100 can be adsorbed onto the surface of a pipe, where rolling friction takes place between the ARDR LUBE-100 particles and the surface of the pipe, thereby effectively reducing wear-and-tear and friction. Laboratory evaluation and field application proved that the ARDR LUBE-100 has good compatibility with drilling fluids, and 1% of ARDR LUBE-100 in drilling fluid has reduced the coefficient of friction by 60%, and rate of wear between drill pipe and casing string reduced by 99.64%, indicating that the use of ARDR LUBE-100 can remarkably wear-and-tear and friction.
