Claims (3)

1. Способ разработки массивной нефтяной залежи с затрудненной гидродинамической связью между нефтенасыщенной породой и подстилающей ее водой из-за наличия в переходной водонефтяной зоне и ниже нее породы, каналы, в которой закупорены отложениями солей и твердых углеводородов, включающий нагнетание вытесняющего агента, периодические определения химического состава добываемой попутно с нефтью воды, периодические замеры пластового давления в добывающих, нагнетательных и контрольных скважинах, отличающийся тем, что по данным о химическом составе пластовой воды, минералов продуктивного пласта и отложений, которыми заполнены фильтрационные каналы в нижних интервалах залежи, смежных с плоскостью водонефтяного контакта, в качестве вытесняющего агента в начальный период проведения работ по поддержанию пластового давления под водонефтяной контакт закачивают жидкие растворители указанных выше отложений: пресную или слабоминерализованную воду и (или) неорганические, органические взаиморастворимые растворители или их смеси.1. The method of developing a massive oil reservoir with a difficult hydrodynamic connection between the oil-saturated rock and the underlying water due to the presence of rock in the transitional water-oil zone and below it, channels in which are clogged with deposits of salts and solid hydrocarbons, including pumping out the displacing agent, periodic determinations of the chemical composition of water produced simultaneously with oil, periodic measurements of reservoir pressure in production, injection and control wells, characterized in that according to chemical m of the composition of formation water, minerals of the reservoir and sediments that fill the filtration channels in the lower intervals of the reservoir adjacent to the oil-water contact plane, liquid solvents of the above sediments are pumped under the oil-water contact during the initial period of work to maintain reservoir pressure: fresh or slightly mineralized water and (or) inorganic, organic, mutually soluble solvents, or mixtures thereof. 2. Способ по п.1, отличающийся тем, что в процессе бурения скважины, предназначенной для закачки под водонефтяной контакт растворителей и вытесняющих агентов, по мере углубления производят определение ее приемистости и при вскрытии интервала, обладающего на принятой глубине закачки заданной приемистостью, дальнейшее углубление скважины прекращают, а выбранный для закачки интервал изолируют от вышерасположенной нефтенасыщенной части разреза.2. The method according to claim 1, characterized in that in the process of drilling a well intended for injection under water-oil contact of solvents and displacing agents, as it deepens, they determine its injectivity and, when opening the interval, which has a given injectivity at the adopted injection depth, further deepening wells are stopped, and the interval selected for injection is isolated from the upstream oil-saturated part of the section. 3. Способ по пп.1 и 2, отличающийся тем, что закачку растворителей под водонефтяной контакт производят периодически.3. The method according to claims 1 and 2, characterized in that the injection of solvents under the oil-water contact is carried out periodically.
