发明名称 METHOD FOR DETERMINATION OF BOTTOMHOLE PRESSURE IN OIL WELL EQUIPPED WITH ELECTRIC SUBMERSIBLE PUMP
摘要 FIELD: oil and gas industry.SUBSTANCE: method lies in measurement of the maximum dynamic head depth for the known well-killing fluid with homogeneous density when bringing the well on to stable production after killing according to the following formula P=?·g·(H-H), where ?- density of the well-killing fluid, kg/m; g - acceleration of free fall, m/s; H- height of the upper perforated openings, m; H- maximum dynamic head depth in the well when bringing the well on to stable production after killing, m.EFFECT: reducing downtime during well surveys, improving accuracy and reliability while determining the bottomhole pressure and simplifying of the bottomhole pressure measurement when bringing the well on to stable production after killing.3 dwg
