Cast polymers reduce downhole torque,drag

摘要

Polymers can be cast at low pressures,rather than injection-molded,to produce engineering-grade components for downhole use.Like many other industry sectors,the upstream oil and gas industry has traditionally been reluctant to embrace polymers.Perhaps this is because compared to metals,their make-up tends to be far more difficult and less well documented by the material standards that we have come to expect for steels.Quite often,this is because the polymer chemical composition is proprietary to the chemical producers.
