The subject of the present invention is a method of modeling the circuit traversed by a drilling mud during drilling, including the well and the surface equipment, in particular the solids separation apparatuses according to which each time sequence is calculated, the mass concentration of each solid and liquid species present in the sludge, the total flow and the particle size distribution of ...
Figure 4 shows the particle size distribution of the bentonite dispersions when these are treated in different ways. Compared to the un-hydrated control sample, the average size of hydrated bentonite particles increased from 16.25 to 32.94 μm. This is different when DEM was added before the hydration of bentonite.

Particle Size Distribution Test Fig. 5 depicts the particle size distribution of the bentonite dispersions treated with different ways. Compared to control sample, the average size of hydrated bentonite particles was much smaller, and the addition of QAS-2 can only influence the particle size slightly, as shown in Table 3.
Crusher - Wikipedia. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
Jan 25, 2011· Fig. 1, Fig. 2, Fig. 3 depict the cation exchange capacity of bentonite as a function of activation time at different particle size distribution. The maximum cation exchange capacity shifted to a lower activation time as the bentonite particle size reduced less than 37 μm. The figures also show the cation exchange capacity variations with temperature.

The basic design criteria for water-based muds used in HTHP wells include the use of Wyoming bentonite at low concentrations and the use of mud additives with only one primary function.
differential distribution and cumulative distribution curves of the clay suspensions treated with formates and PEDA, respectively. Addition of inhibitors with the concentration of 0.5 wt% changes the clay particle to a larger size obviously. The particle size order is NaCOOH
Baroid Grouting Products. Grouting products are designed to create a low permeability seal in the annular space between the borehole wall and the installed product, such as a well casing or geothermal heat loop, or for the abandonment of a borehole or decommissioning of an existing well where a seal to the surface is required.
