Enhancement of Oil Layers Recovery by the Impulse-wave Impact

Today in Russia idles about 20 percent of oil wells. The cause is natural process and factors, attend oil production. With the lapse of time, in the issue of oil selection and disturbance of the system oil-rock, the last consolidates under the influence of overlying layers and reduces permeability. This, in turn leads to decrease of oil well productivity and pumping well receptance. For temporal increase of oil stratum permeability one can apply different methods of impact. For example: stratum ruptures by fluid (HFF) and powder gases of high pressure, acid treatments, thermic -gas-chemical impact, plasma and others. Given fact that the main cracks in the reservoir makes great heterogeneity, complicating the process of extracting oil, as well as the limited time the positive effect of the ruptures, there is a need to look for other approaches to addressing this critical issue. Our work gives a detailed description of one of these solutions - a method of impulse-wave impact (IWI).
