Abstract
The utility model relates to a multifunctional deep well pump which belongs to the field of a deep well pump in oilfields and comprises a pump cylinder [40], a plunger assembly [50], a standing valve group [60] and a pumping rod [70], wherein the pumping rod is hollow and the plunger assembly and the standing valve group are also hollow. The plunger assembly is sheathed outside the pumping rod [70] and can slide on the pumping rod within a certain range. The pumping rod is provided with a top and bottom penetrating path inside in the pump cylinder. The pumping rod drives a plunger to move in the reciprocating mode in the pump cylinder to form the discontinuous opening and closing among the plunger, the hollow standing valve group and the pump cylinder, and thus, the suction force is formed. The multifunctional deep well pump of the utility model provides a smooth path in the pump for the testing apparatus to pass. At the same time, the utility model can be used for adding a heating rod or the chemical agent when the utility model encounters the thick oil area.
