METHOD FOR EFFICIENT MEASUREMENT OF LIQUID DEBIT IN OIL OR GAS CONDENSATE WELL AND DEVICE FOR ITS REALISATION

摘要

FIELD: oil and gas production.;SUBSTANCE: device comprises horizontal reservoir equipped with hydraulic cyclone head in upper part for separation of gaseous carbohydrates, which is separated inside by partition open in upper part and separating reservoir into receiving and discharge compartments. There is an insert in partition with profiled drain slot, which sets level in receiving compartment at the value adequate for daily debit of well by liquid. Besides slot profile provides for linear dependence of level on debit with accuracy in working range of debits of ±5%. For this purpose slot profile at sides it limited by curves where a - any positive number, value of which is accepted in selection of range of measured liquid debits, and at the bottom it is limited by axis of abscissa limited by values ±x, corresponding to value y=0.25 cm. Between area of liquid drain to reservoir wall and separating partition with profiled slot there is a damping perforated partition provided.;EFFECT: higher accuracy of debit measurement, increased quantity of measured wells per calendar day.;2 cl, 1 ex, 1 tbl, 2 dwg
