Electric submersible screw pump (ESPCP) is a combination of screw pump (PCP) and electric submersible pump (ESP), which is a downhole fluid lifting system that is very suitable for horizontal wells. It belongs to a rodless pump system and avoids tube and rod friction loss . Screw pump can withstand the formation of sand. The Kulin horizontal well project started in early 2002 and completed in December 2003. The first horizontal well was Kulin082 (KL082) and the second one was Kulin083 (KL083). After the completion of the project, the electric submersible screw pump was used for artificial lift. KL082 initial Nissan liquid 708bbl, Nissan oil 531bbl, moisture content 25%; KL083 daily production 518bbl, Nissan oil 394bbl, moisture content of 24%. In view of the unconsolidated sand in the adjacent Duri field, serious sand production greatly reduces the pumping efficiency of the rod pump, whereas the horizontal well is difficult to control with the naked eye prefabricated screen pipe production. Therefore, the Kulin horizontal well is sand-tolerant Rodless pump for artificial lift. Because the screw pump can not be used for horizontal wells, ESP can not deal with sand, so the final selection of ESP pumps.
