Abstract

Способ электрохимической подготовки закачиваемой в нефтегазоносный пласт жидкости с целью изменения сорбционной емкости коллектора достигается использованием электродных пар с соотношением площадей ≠1, размещенных в разных корпусах из электроизоляционных материалов, посредством создаваемой на них разности потенциалов за счет поляризации электродов прокачиваемой через них жидкостью или за счет подачи на них разности потенциалов от источника питания постоянного тока, при котором основная часть электрической мощности расходуется не на инициирование электролизных процессов, а на изменение поляризационной составляющей, прокачиваемой через электродные пары жидкости; с подключением в любой последовательности ко всем или к одной из них электрической нагрузки соответствующей поляризующей способности, прокачиваемой через электродную пару жидкости и позволяющей поддерживать потенциал наводимый на электродной паре ≠0 В.The method of electrochemical preparation of the fluid injected into the oil and gas reservoir to change the sorption capacity of the reservoir is achieved by using electrode pairs with an area ratio of ≠ 1 placed in different housings of electrical insulating materials, by creating a potential difference on them due to the polarization of the electrodes by the fluid pumped through them or by feeding on them the potential difference from the DC power source, at which the bulk of the electric power is consumed by e to initiate electrolysis processes, and to change the polarization component pumped through the electrode pairs of the liquid; with connection in any sequence to all or to one of them of an electric load of the corresponding polarizing ability, pumped through the electrode pair of liquid and allowing to maintain the potential induced on the electrode pair ≠ 0 V.
