摘要
Abstract
The positive and adverse influences of oil-based drilling fluid on ROP are analyzed with the general equation for drilling rate in terms of the properties of oil-based drilling fluid. It indicates that the formation lithology superior to the well type and drilling fluid exerts the main influence on ROP. The optimum type of drilling bit and optimization of drilling parameters play a more important role in improving ROP than the formulation and performances of drilling fluid. Through regulating the composition of drilling fluid, cleaning bits, alternating wettability of bottom-hole rock, improving the extreme pressure lubricity, adding neutral wetting agent, mixing high temperature stability oil-soluble macromolecule agent to replace organic clay and oxidized asphalt, reducing the contents of micron and submicron particles, modifying shear thinning behavior and increasing efficiency of carrying cuttings to help improving the ROP effectively.关键词
