Effective way of creation of microcracks wave impact on layer

Hydraulics and Engineering Hydrology

An alternate method of enhanced oil recovery oil reservoir is a method of shock-wave stimulation. This method consists in creating a shock wave in the well. Shock wave before reaching the bottom of the well-recognizedand creates shock pulse. The intensity of the bottom hole pressure is determined by the shape and frequency of the pressure change in the mouth. Unlike traditional fracturing is not leading to increased impermeability collector shock-wave action increasesthe network of microcracks and, thus, increases the permeability of the reservoir. A technology that shows the advantage of this method compared with hydraulic fracturing and technical point of viewand from an economic prospects. The results of a natural experiment in NGDU Bashneft (Bashkiria) are given. The physical-mathematical model of shock-waveis developed.
