Method for determining intermittent pumping system through oil-well pump dynamic fullness well testing
The invention discloses a method for determining an intermittent pumping system through oil-well pump dynamic fullness well testing. The method for determining the intermittent pumping system through oil-well pump dynamic fullness well testing comprises the steps of (1) determining a net stroke of a piston of an oil-well pump through synchronous measurement of a continuous polish rod load-and-time curve and a polish rod continuous displacement-and-time curve, and using a percentage between the net stroke and a gross stroke as a fullness measuring value; (2) building a complete oil-well pump dynamic fullness decreasing history curve according to continuous read and continuous analysis of the fullness, and obtaining an etamax and an etac according to the complete oil-well pump dynamic fullness decreasing history curve; (3) using the time spent by the process that the fullness of an oil well with the given characteristic decreases from the etamax to the etac as a fixed pumping time, and selecting different to-be-pumped times Tg to form an intermittent period; (4) using a percentage between the fixed pumping time and a well shutdown time as a pumping duty ratio, compiling a series of intermittent pumping systems according to different period systems, and determining an optimum intermittent pumping system according to the maximum daily output method and a minimum pumping duty ratio. The method for determining the intermittent pumping system through oil-well pump dynamic fullness well testing enables a sucker-rod pumping oil well to achieve maximum capacity, and reduces energy consumption and operating cost.
