Abstract
1. Способ одновременно-раздельной добычи нефти из двух пластов одной скважины, включающий определение их геолого-технических характеристик, спуск в скважину пакера, который располагают между двумя пластами, спуск в скважину одной колонны лифтовых труб с одним электродвигателем с приводом на два насоса и хвостовиком, отличающийся тем, что нижний насос при спуске располагают на расстоянии от пакера, равному расчетному динамическому уровню флюида нижнего пласта, при этом продукт нижнего пласта за счет давления в подпакерной зоне поступает на прием нижнего насоса и далее через обратный клапан (регулятор давления) подается в межтрубное пространство, перемешивается с флюидом верхнего пласта и верхним насосом откачивается на поверхность.2. Способ одновременно-раздельной добычи нефти из двух пластов по п.1, отличающийся тем, что напорная характеристика каждого насоса может меняться в соответствии с геолого-техническими характеристиками каждого пласта.1. The method of simultaneous and separate oil production from two layers of the same well, including determining their geological and technical characteristics, lowering the packer into the well, which is located between the two layers, lowering into the well one column of elevator pipes with one electric motor driven by two pumps and a liner , characterized in that the lower pump during descent is placed at a distance from the packer equal to the calculated dynamic level of the fluid of the lower reservoir, while the product of the lower reservoir due to pressure in the sub-packer zone to receive the lower pump and then through the check valve (pressure regulator) it is fed into the annulus, mixed with the fluid of the upper reservoir and pumped to the surface by the upper pump. 2. The method of simultaneous-separate oil production from two reservoirs according to claim 1, characterized in that the pressure characteristic of each pump can vary in accordance with the geological and technical characteristics of each reservoir.
