Comparative evaluation of the effectiveness of application of propants of fractions 16/30 AND 16/20
The main properties of the proppants of fractions 16/20 and 16/30 are considered in terms of the maximum effect when applied. The tests of two types of proppants (aluminosilicate and magnesia-quartz), as well as calculations of the dimension-less conductivity of the fracture (the main parameter) used to characterize the well after hydraulic fracturing, showed that at a pressure of more than 6000 p.s.i. the conductivity and effect of the use of aluminosilicate proppants of fraction 16/30 is higher than that of proppants of fraction 16/20 of both types. The presence of non-stationary cyclic loads reinforces this advantage.
