Дл этого в масштабе последовательно сни.мают две диаграммы (Д) активной МОШ.НОСТИ электрогидродвига- тел привода насоса при ходе устьевого штока вверх. Первую Д снимают при .меньшем давлении на устье, а вторую - при повышенном давлении. Одновременно снимают Д устьевого давлени . По Д мош- ности и устьевого давлени при двух разных значени х устьевого давлени определ ют средние разностные значени мощности ДР (кВт) и устьевого давлени АР(МПа) при ходе устьевого штока вверх. Затем определ ют дебит Q (т/сут) С по формуле АР- у ,где Yny - удельный вес жидкости в поверхностных услови х, т/м The invention relates to the extraction of oil and allows to increase the accuracy and simplify the method for determining the flow rate of a well (C) equipped with a sucker-rod downhole pump. To this end, two diagrams (L) of the active MOSH.T. electrohydrodvigatel pump drive are shown successively in scale at the stroke of the wellhead shaft upwards. The first D is removed at a lower pressure at the mouth, and the second at elevated pressure. Simultaneously remove the wellhead pressure. According to the D power and wellhead pressure at two different wellhead pressure values, the average difference values of the power HL (kW) and wellhead pressure AR (MPa) are determined with the wellhead rod up. Then, the flow rate Q (t / d) C is determined by the formula AP-y, where Yny is the specific gravity of the liquid under surface conditions, t / m

Изобретение относитс к области добычи нефти и может быть использовано дл измерени дебита скважин, оборудованных глубинными штанговыми насосами с приводом от станков-качалок.The invention relates to the field of oil production and can be used to measure the flow rate of wells equipped with submersible sucker-rod pumps driven by pumping units.
Целью изобретени вл етс повышение точности и упрощение способа определени дебита скважины.The aim of the invention is to improve the accuracy and simplify the method of determining the flow rate.
Способ осуществл ют следующим образом .The method is carried out as follows.
Снимают в масштабе последовательно две диаграммы активной мощности, потребл емой электродвигателем привода насоса, при ходе устьевого штока вверх. Первую диаграмму снимают при меньшем давлении на устье скважины, а вторую - при повышенном давлении на устье, полученном , например, за счет прикрыти задвижки на выкидной линии скважины. Одновременно с диаграммами .мощности снима- ют диаграммы устьевого давлени .Two diagrams of the active power consumed by the pump drive electric motor are taken to scale successively during the wellhead stroke upwards. The first diagram is removed at a lower pressure at the wellhead, and the second at elevated pressure at the wellhead, obtained, for example, by covering the valve on the flow line of the well. Simultaneously with the power diagrams, wellhead pressure diagrams are removed.
