“…As experiments on reverse imbibition of clear samples show [4], filtration of both phases in reverse directions is uniform during all flow; every phase takes its own pore channels system. Reverse imbibition can be studied as ordinary one-dimensional two-phase filtration penetrability for reversed flow can differ from corresponding functions during one-dimensional flow of both phases further quality study this difference is not taken into account Experimental studies [4] on holding water uniformities during cyclic impact showed that time necessary for injected water to hold in non-uniformities completely approximately equal to time necessary for reversed or direct capillar imbibition of the given non-uniformity with the rest of the layer. Now, let's compare speed of oil "substitution" in a block during cyclic impact on the layer reversed capillar imbibition, which is shown by formula…”

Pulse method of non-stationary flooding is a continuous regulation process. Its efficiency is determined by the reserve recovery stage and is chosen after thorough analysis of the development, when the oil deposits are determined differentially on the field zones and deposits and there is a positive forecast of their extraction by existing methods. Then comparing development parameters of different variants of pulse non-stationary flooding the best development method is chosen. In this case bottom-hole or well head devices (energizers, shaker apparatus, pulsators etc.) are used for pulse flooding in order to boost reverse capillary imbibitions of closed oil zones and reversal filtration of the injected water. Experiments showed, with the increase of vibration frequency at the given parabolic law of pressure deviation fluid penetration rate into the fractured-porous layer increases sharply. Preliminary results showed high efficiency of selective application of complex flooding of hydrocarbon deposit.

“…Strict analytical solution on determining quality effect and pulse non-stationary flooding in this formulation is rather difficult [4]. But if we solve several practical problems, for example choose the best variant, its fulfillment; we will get comparative characteristics of process efficiency.…”

“…One of the promising ways of oil recovery from hydrocarbon layers increasing and the produced water relative volume reducing is the method of liquid non-stationary pulsed into injection wells pumping and the effectiveness of which is confirmed by theoretical studies [1][2][3][4][5][6][7][8][9][10][11][12][13]. In this regard, there is a need to conduct laboratory studies to determine the optimal parameters for the method application.…”

The paper presents laboratory studies of impulse water injection on the rock samples. A large number of experimental data were obtained. According to the experimental data, a regression analysis was carried out, on the basis of which qualitative correlations between factorial and resultant characteristics were revealed. Taking into account the mathematical analysis of the data obtained, graphical dependencies were constructed. As the fluid oscillation frequency increases, the amount of liquid passing through the sample of the porous medium increases, with the greatest value of fluid leakage through the rock samples reaching in the frequency range 600 ... 1000 Hertz.

“…As a consequence, the injection wells gradually reduce the injection capacity, which adversely affects the injection balance. To restore the injection capacity of a well, the following methods are used: drained acid formation treatment, hydraulic fracturing, hydraulic acid treatment without sand cracks fixing, thermal treatment of formation, mud-pulse one-time treatment, draw-down pressure, shot-firing operations, etc [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

During water injection in the bottomhole zone, except corrosion products, which are the main plugging agent, mechanical particles containing in the injected water are collected. They form a sediment that pollutes the filtration channels of the formation, gradually reducing the absorption capacity of the injection well. In order to inject as much water into the formation as it's possible during the planning period, it is necessary to carry out repairs in a well with the help of one-time mud-pulse treatments. The introduction of this express method of treatment allowed reducing the material costs significantly and maintaining a stable level of injection and a stable coefficient of selection.
