Abstract

Изобретение относится к нефтяной промышленности, в частности к измерению показателей нефтяных скважин и может быть использовано в системах определения депрессии пласта. Сущность изобретения состоит в способе определения забойного давления. Способ включает отбор пробы пластовой жидкости и определение лабораторным путем плотности воды и нефти в пластовой жидкости, измерение динамического уровня воды и нефти и давления газа на устье эксплуатационной колонны. По полученным данным рассчитывают значение забойного давления. Технический эффект заявляемого изобретения состоит в более точном и относительно простом способе измерения забойного давления, позволяющем оперативно корректировать работу скважины.The invention relates to the oil industry, in particular to measuring the performance of oil wells and can be used in systems for determining the depression of the reservoir. The invention consists in a method for determining bottomhole pressure. The method includes sampling the formation fluid and determining in a laboratory way the density of water and oil in the formation fluid, measuring a dynamic level of water and oil and gas pressure at the mouth of the production string. According to the obtained data, the bottomhole pressure value is calculated. The technical effect of the claimed invention consists in a more accurate and relatively simple method of measuring bottomhole pressure, which allows you to quickly adjust the operation of the well.
