Description
Известен способ раздельного отбора нефти и воды из обводненной фонтанной скважины. Этот способ предусматривает подачу энергии в турбину в виде сжатого газа с поверхности.There is a method of separate selection of oil and water from a watered gushing well. This method provides for the supply of energy to the turbine in the form of compressed gas from the surface.
Предлагаемый способ отличаетс от известных тем, что испОльзует избыток энергии в добываемой нефти. Это достигаетс тем, что нефть пропускают через турбину, соединенную валом с центробежным насосом, откачивающим воду на поверхность.The proposed method differs from the known ones in that it uses an excess of energy in the extracted oil. This is achieved by allowing the oil to pass through a turbine connected by a shaft to a centrifugal pump that pumps water to the surface.
Сущность предлагаемого способа заключаетс в использовании избытка энергии, образующегос при подъеме нефти в случае недопущени в подъемную колонну поступающей из пласта воды. Избыток энергии характеризуетс повыщение.м буферного давлени на устье скважины по сравнению с давлением на устье при фонтанировании смеси с водой. Образующийс перепад давлени и предлагаетс использовать дл привода в действие центробежного насоса с целью подъема на поверхность, раздельно от нефти, поступающей в скважину воды.The essence of the proposed method is to use the excess energy generated during the rise of oil in the event that water coming from the reservoir is prevented from coming into the lifting column. The excess energy is characterized by an increase in .m of buffer pressure at the wellhead compared to the pressure at the well when flowing the mixture with water. The resulting pressure drop is proposed to be used to drive a centrifugal pump in order to rise to the surface, separately from the oil flowing into the well water.
- На фиг. 1 и 2 изображено устройство дл осуществлени описываемого способа.- In FIG. 1 and 2 illustrate an apparatus for carrying out the described method.
На пути движени фонтанирующей нефти в нижней части фонтанных труб устанавливаетс гидравлическа турбина /, соединенна общим валом с центробежным насосом 2 (фиг. 1). Безводна нефть из нефтенасыщенной части пласта проходит в нефт ной лифт 3 (фиг. 2) через турбину / и, отдава свою энергию, приводит в движение насос 2. Пластова вода из водонасыщенной части пласта поступает в скважину, откуда центробежным насосом подаетс на поверхность по кольцевому пространству 4.In the path of the spouting oil, a hydraulic turbine / is mounted in the lower part of the flow pipes, connected by a common shaft with the centrifugal pump 2 (Fig. 1). The anhydrous oil from the oil-saturated part of the reservoir passes into the oil elevator 3 (Fig. 2) through the turbine / and, giving up its energy, drives pump 2. The reservoir water from the water-saturated part of the reservoir enters the well, from where the centrifugal pump is supplied to the surface through an annular space 4.
Предлагаемый способ позвол ет целесообразно использовать энергию пласта дл полезного процесса раздельного отбора нефти и воды обводненной скважины с целью предупреждени образовани эмульсий.The proposed method makes it possible to efficiently utilize the formation energy for a useful process for the separate extraction of oil and water from a watered well in order to prevent the formation of emulsions.
