DETERMINATION OF THE WELL JET PUMP OPERATION MODEDETERMINATION OF THE WELL JET PUMP OPERATION MODE

Methodology of decision of the system of equalizations describing pressure description of downhole jet pump is offered. In accordance with the algorithm driven to work determination of hydraulic losses in a working stream on an area between working attachment and chamber ofmixing comes true with the use of method of progressive approximations. The sequence of realization of calculation operations and program are worked out for their realization. The calculation algorithm driven to work allows to change exactness of prognostication of the pressure created by jet pump and duration of procedure of his determination. Realization of the offered calculation complex can come true with the use of language of Delphi and program resources of PTC Matchad.
