Design and application of concentric double-tube hydraulic pump sand carrying oil production diagnosis and optimal design system

To improve the rationality of concentric double-tube hydraulic pump sand carrying oil production project design,to prevent sand deposition and improve development efficiency,concentric double-tube hydraulic pump sand carrying oil production diagnosis and optimal design system were discussed,whichcould realize condition diagnosis and optimal design through deal with production data and process design data.The technological process and the key technology of concentric double-tube hydraulic pump sand carrying oil production diagnosis and optimal design system were mainly described in Kongdian oilfield. The application results showed that the system could realize condition diagnosis and process parameters optimal design.
