Annotation:

The operation of small-diameter wells and small-diameter lateral boreholes are associated with the problems of placing equipment of the required bearing capacity in them. In addition to high load-bearing capacity, the equipment should be able to work efficiently and for a long time in complicated operational conditions. The main complicating factor when extracting oil from lateral boreholes is the complex inclinometry of wells. Complex inclinometry and the small diameter of the lateral boreholes cause intensive wear of oil-producing equipment. At the same time, the equipment placing environment in the mother part of the borehole with lateral boreholes is unacceptable due to the low production capabilities of the system. The problem of efficient operation of small- and medium-production oil wells with small-diameter lateral boreholes has been solved through the use of pumping units with cable-type sucker-rod hangers in such wells.
