n: A kind of device that processes grained solid material. Applied for processing various drilling fluid treating chemicals, usually for processing coarse and inert bridging material.

n: a forged or cast steel fitting for a wire rope or a strand. It has a basket with adjustable bolts that secure rope ends. bridging materials n pI: the fibrous, flaky, or granular material added to a cement slurry or drilling fluid to aid in sealing formations in which lost circulation has occurred. See lost circulation, lost circulation material.

n: The effect of solids forming an obstruction or bridge in the fluid passages. Bridging in reservoir pores may take place with solids over about a third of pore size. Bridging may be deliberate (additives in fluids to reduce fluid loss) or a problem (rese

collection of materials, usually from the formation that interlocks at some point in the well, often in the annulus and may stop flow or stick the pipe in place.

n: See material.

n: The fissile or grained fibre material added into drilling fluid or cement slurry. Used to bridge leakage formation.

fluid loss control material that bridges against the leakoff site.

n: A kind of simulated experimental apparatus used to investigate technology of plugging thief zone.

n: The solid particle that forms cake in the borehole face or formation pore.

n: The plugged zone formed by plug agent in the thin porous formation. The plug agent is added into the drilling fluid.

n: A kind of fissile and indifferent bridging material, usually used as plugging agent of honeycombed leakage zone.

n: a process of molecular bridging of polymers with other chemical substances that alters viscosity and shear rates to enhance lifting of bit cuttings and increase drilling rates.
