Claims (9)

1. Способ обработки продуктивного пласта в призабойной зоне скважины, включающий нагрев жидкости в призабойной зоне и удаление из призабойной зоны продуктов кольматации, отличающийся тем, что перед нагревом жидкости призабойную зону скважины герметизируют в верхней части, образуя при этом призабойную камеру, а после нагрева охлаждают жидкость в объеме призабойной камеры и затем разгерметизируют эту камеру перед удалением из нее продуктов кольматации.1. The method of processing the reservoir in the bottomhole zone of the well, comprising heating the fluid in the bottomhole zone and removing from the bottomhole zone the products of mudding, characterized in that before heating the fluid, the bottomhole zone of the well is sealed in the upper part, forming a bottomhole chamber, and after heating it is cooled liquid in the volume of the bottomhole chamber and then depressurize this chamber before removing from it the products of mudding. 2. Способ по п.1, отличающийся тем, что нагрев жидкости в призабойной камере осуществляют выше точки кипения одной из составляющих ее легких фракций нефти, например бензина. 2. The method according to claim 1, characterized in that the heating of the liquid in the bottomhole chamber is carried out above the boiling point of one of its constituent light fractions of oil, for example gasoline. 3. Способ по п.1, отличающийся тем, что нагрев жидкости в призабойной камере осуществляют выше точки кипения воды. 3. The method according to claim 1, characterized in that the heating of the liquid in the bottomhole chamber is carried out above the boiling point of water. 4. Способ по п.1, отличающийся тем, что нагрев жидкости в призабойной камере осуществляют выше точки кипения одной из составляющих ее тяжелых фракций нефти, например масел. 4. The method according to claim 1, characterized in that the heating of the liquid in the bottomhole chamber is carried out above the boiling point of one of its constituent heavy fractions of oil, for example oils. 5. Способ по любому из пп.1-4, отличающийся тем, что нагрев жидкости в призабойной камере осуществляют мгновенно, например взрывом. 5. The method according to any one of claims 1 to 4, characterized in that the heating of the liquid in the bottomhole chamber is carried out instantly, for example by an explosion. 6. Способ по любому из пп.1-5, отличающийся тем, что охлаждение жидкости в объеме призабойной зоны скважины осуществляют принудительно с использованием специальных средств, например термопар. 6. The method according to any one of claims 1 to 5, characterized in that the cooling of the liquid in the volume of the bottomhole zone of the well is carried out forcibly using special means, for example thermocouples. 7. Пакер для обработки продуктивного пласта в призабойной зоне скважины, содержащий корпус со средствами радиального уплотнения и средство подвески, отличающийся тем, что его нижняя торцевая поверхность выполнена в виде вогнутой поверхности вращения второго порядка. 7. A packer for processing a productive formation in the near-wellbore zone of the well, comprising a housing with radial sealing means and suspension means, characterized in that its lower end surface is made in the form of a concave second-order rotation surface. 8. Пакер по п. 7, отличающийся тем, что вогнутая поверхность вращения второго порядка выполнена полусферической. 8. The packer according to claim 7, characterized in that the concave surface of rotation of the second order is made hemispherical. 9. Пакер по п. 7, отличающийся тем, что вогнутая поверхность вращения второго порядка выполнена параболоидной. 9. The packer according to claim 7, characterized in that the concave surface of rotation of the second order is made paraboloid.
