SUCKER-ROD PUMP TESTING PLANT Russian patent published in 2004 - IPC

FIELD: oil producing industry.

SUBSTANCE: relates to methods of testing processes taking place sucker-rod pumps and it can be used for investigation and testing of pumps. Proposed plant has frame for fastening sucker-rod pump with lock made for installation at required angle of tilting of axles of sucker-rod pump, reservoir with working fluid for inner space of sucker-rod pump, reciprocating motion mechanism of sucker-rod pump with drive interacting with plunger of sucker-rod pump, and pump parameter measuring and recording system. Plant is furnished additionally with control panel. Reciprocating motion mechanism is made in form of main additional hydraulic drives operated by control panel. Main hydraulic drive is rigidly secured on frame coaxially with sucker-rod pump. Its piston is connected with drive. Additional hydraulic drive is fitted in main drive cut. Piston of additional hydraulic drive is connected with one part of drive, and cylinder, with other part of drive. Limit switches are installed on frame for interacting with cylinder of sucker-rod pump in extreme positions. Plant is convenient in use. Proposed device improves accuracy of measurement of parameters of sucker-rod pump under testing owing to possibility of control of operation of process of testing to bring conditions of testing of conditions of pump operation in well.

EFFECT: increased reliability owing to prevention of emergency situations by providing control over critical displacements of tested sucker-rod pump.
