Drilling Lab - Drilling Fluid Viscometer

Aim The aim of experiment is finding a drilling mud viscosity which composed of bentonite and water using a viscometer. Theory Drilling mud is a mixture of water and mud (Clay) addition to some other minerals and special chemical materials called “additives” (Kate, 1998), that used with water and mixed to maintain well stability during the process of drilling. Sometimes mud can be non-aqueous regarding to …

For polymer ,drilling, fluids, Chien recommends computing the ,apparent viscosity, as follows: In operation, the cuttings slip velocity is computed from an equation similar to Chien's. From the computed value, an acceptable flow rate is determined based on the minimum rate that would hold the cuttings stationary plus an additional rate increase to clean the hole.

The flow behaviour ,of drilling, fluids is complicated by the variation of ,apparent viscosity, with rate of shear or flow. Consequently, the Newtonian fluid equations are altered for application to typical ,drilling mud, systems. Swab and surge pressures can be computed using a calculation steps based on basic ,mud, flow Equations 1 to 10.

In evaluating drilling muds, it is common practice to report the effective viscosity at 600 rpm. This quantity is called the apparent viscosity, AV, and is given by (5.25)¯ AV = 300 × θ600 600 = θ600 2 Note that the term apparent viscosity is used by some authorities in a more general sense as an alternative for effective viscosity.

PV represents the viscosity of a mud when extrapolated to infinite shear rate on the basis of the mathematics of the Bingham model. (Yield point, YP, is the other parameter of that model.) A low PV indicates that the mud is capable of drilling rapidly because of the low viscosity of mud exiting at the bit.

A low PV indicates that the mud is capable of drilling rapidly because of the low viscosity of mud exiting at the bit. High PV is caused by a viscous base fluid and by excess colloidal solids. To lower PV, a reduction in solids content can be achieved by dilution of the mud. Alternate Form: plastic viscosity. See: apparent viscosity
