Kind of oil well fracking
(1) hydraulic fracking, mainly by changing the state of the fluid flow, reduce energy consumption and reduce the formation of fluid flow near the lower resistance to complete. So that it can inject the proppant to achieve the diversion effect, so that the oil production.
(2) high energy gas fracturing, boosted by rapid cracks, such cracks are not easily closed during the generation of cracks naturally there will be some debris off, these chips will be self-supporting from the cracks. Meanwhile, in a high temperature wax soluble pores, resin and asphaltene, high temperature can make crude oil viscosity reduction.
(3) acid fracturing ,it is the acid as a fracturing fluid without proppant fracturing.
