摘要： Arrangement for the lifting of hydrocarbons in oil field wells, comprising a lifting assembly formed by a fluid collecting hose and a fluid suction tube within the well casing. The suction tube extends along the collecting hose, which has an open upper end, through which passes the upper section of the suction tube, which has an end attached to the pulling cable of the “collecting hose/suction tube” assembly. The lower end is closed by means of a one-way check valve, letting the fluid flow into the space formed between the hose and said tube. The upper section projecting beyond the open upper end of the collecting hose has a laterally conformed fluid discharge opening. When the “hose/suction tube” assembly rises by action of the pulling cable and reaches the end of its travel, said discharge opening is positioned within a sealed chamber in the wellhead defined between a pair of sealing rings, so that the fluid may be discharged by means of a suction pump and/or under the gas pressure from within the well casing.

摘要： An extraction arrangement for the extraction of hydrocarbons that allows reducing related costs by simplifying the structure, reducing the number of parts used in this type of arrangement, and consequently reducing the associated risks and facilitating both operation and maintenance tasks, also optimizing the extraction capacity of the pump by not having leaks in seals because the latter are not necessary as it is a fixed tube.

摘要： A compressor unit for oil wells, operating independently from conventional AIB rod pumps, which allows regulated gas extraction to keep the gas pressure constant inside the well and thus allowing the extraction of oil without the inconveniences of traditional pumping systems.
