Abstract
Изобретение относится к нефтяной промышленности, касается способов измерения дебита нефти, а именно к методам определения проницаемости пласта и восстановления пластового давления. Сущность изобретения состоит в способе измерения дебита нефтяных скважин, который включает измерение давления, температуры и динамического уровня пластовой жидкости и определение лабораторным путем обводненности пластовой жидкости, вязкости нефти, плотности воды и нефти. По полученным значениям рассчитывают изменение забойного давления, строят график восстановления пластового давления и полученную кривую аппроксимируют по формулеи определяют прогнозное значение восстанавливаемого пластового давления и время для проведения измерения динамического уровня, проводят расчет коэффициента проницаемости пласта и рассчитывают дебит нефти, газа и воды в эксплуатационной колонне по соответствующим формулам. Технический эффект заявляемого изобретения заключается в том, что способ учитывает основные параметры пласта и это позволяет адекватно управлять процессом эксплуатации скважин и интенсифицировать добычу нефти.The invention relates to the oil industry, relates to methods of measuring the flow rate of oil, and in particular to methods for determining the permeability of the reservoir and the restoration of reservoir pressure. The essence of the invention consists in the method of measuring the flow rate of oil wells, which includes the measurement of pressure, temperature and dynamic level of reservoir fluid and the determination by laboratory method of the water content of reservoir fluid, viscosity of oil, density of water and oil. Based on the obtained values, the change in bottomhole pressure is calculated, a reservoir pressure recovery graph is constructed and the resulting curve is approximated by a formula to determine the predicted value of the reservoir pressure to be restored and the time for measuring the dynamic level, the reservoir permeability coefficient is calculated and the oil, gas and water production rate corresponding formulas. The technical effect of the claimed invention is that the method takes into account the main parameters of the reservoir and this allows you to adequately manage the process of well operation and to intensify oil production.
