Technically selective fracturing proppant production efficiency

Selective proppant is the use of new technologies, in the conventional proppant sand attached to the surface layer of film having let the oil pass impede water through function.

This membrane is formed, similar to the daily use of the tarpaulin, so that the outer surface of the  Proppant  optionally a hydrophobic oleophilic characteristics

.
This layer of membrane added  Proppant   the first of its kind at home and abroad. Since this layer of film is very thin, only a diameter of human hair 1/10, to form this layer of

film, the conventional Proppant  has a crushing rate, conductivity is high; as density, settling slowly; thickening amount of optimization,

Reduce the costs of measures to reduce the fracturing fluid residue formation damage and so on. Meanwhile, since this layer of film presence in the formation under great

pressure, optionally proppant is not easily broken characteristics, to ensure the oil flow smoothly, and to ensure the oil production while limiting water production.
This technique will be plugging and fracturing techniques combined by fracturing the Proppant  brought to the cracks, forming a prolific oil-less water production of the

"highway", thereby reducing the ineffective production fluid, reduce ground sewage difficult to treat, reduce production costs.
