Optimum Selection & Application of Hydraulic Jet Pump (HJP)

Abstract

Hydraulic jet pumpit’sone of the artificial lift method. The conept of this pump depends on creating a pressur difference at the bottom hole by pumping the power fluid with a larg pressure and flow rate, and the pressure difference occurs as a result of a change in diameter between nozzle and throatwhich works to produce reservoir fluid. The decreasing in pressure with time as a result of the depletion of the reservoir itcan be caused a problem if itdon’t control in a way that enables us to produce most of the hydrocarbon available for produced .Therefore, itrecommended to apply artificial lift methods with a high production capacity,Hydraulic jet pump is distinguished pump,and through it can be design optimal selection of parameters by various combinationsby using completion data forx well in block 6 oil field. In this research hydraulic jet pump can be selected because it have high productivitywhen it compare with othertype of pumps and it can be usePIPESIMsoftware tosimulate and design hydraulic jet pump model includes nodal analysis before and after represent it, and a system analysis in several cases that includes analysisof Cavitations ratio -Critical Flow Ratio & Efficiency-jet pump power volumetric. From the result,can beget nozzle-throat combinations(6H-7I-8I-8J), which have the same production rate (800 STBD), 8J it is the bestoption because it hada best criteria of (Cavitations ratio -Critical Flow Ratio & Efficiency).
