Abstract
Изобретение относится к нефтедобывающей промышленности, в частности к измерительной технике, и может быть использовано в системах централизованного контроля для измерения дебита двухфазной трехкомпонентной продукции скважин. Сущность изобретения состоит в способе измерения дебита продукции нефтяных скважин, который включает измерение уровня жидкости в сепарационном мернике. Дополнительно измеряют перепад давления, создаваемый между уровнем нефтяной жидкости в сепарационном мернике и уровнем жидкости в уравнительном сосуде дифманометра, установленным на сепарационном мернике, и расчетным путем определяют дебит нефтяной жидкости и массовый дебит нефти и пластовой воды. Дополнительно рассчитывают дебит газа в нормальных условиях по измеренному перепаду давления в диафрагме, установленной на линии отвода газа из сепарационного мерника. Сущность изобретения состоит также в устройстве для автоматического измерения дебита нефтяных скважин. Устройство содержит сепарационный мерник, поплавок, датчик уровня с магнитным индикатором, распределительную батарею, исполнительные механизмы, установленные на сливной и наливной линиях, и блок управления. В устройстве дополнительно установлены два дифманометра. Один из них соединен через разделительный сосуд, наполненный разделительной жидкостью, с нижней и средней частью мерника ниже предполагаемого уровня нефтяной жидкости. Другой дифманометр через диафрагму соединен с трубопроводом отвода газа в коллектор. Выходы дифманометров соединены с блоком управления. Заявляемое изобретение позволяет измерить дебит скважины не только по нефти и пластовой воде, но и поThe invention relates to the oil industry, in particular to the measuring technique, and can be used in centralized control systems for measuring the flow rate of two-phase three-component well production. The essence of the invention consists in the method of measuring the flow rate of production of oil wells, which includes the measurement of the level of liquid in the separation measuring device. In addition, the pressure drop created between the level of oil fluid in the separation measuring device and the liquid level in the leveling vessel of the differential pressure gauge mounted on the separation measuring device is measured, and the flow rate of the oil liquid and the mass flow rate of oil and produced water are determined by calculation. Additionally, the gas flow rate is calculated under normal conditions from the measured pressure drop in the diaphragm installed on the gas outlet line from the separation measuring device. The invention also consists in a device for automatically measuring the flow rate of oil wells. The device contains a separation measuring device, a float, a level sensor with a magnetic indicator, a distribution battery, actuators installed on the drain and filling lines, and a control unit. The device additionally has two differential pressure gauges. One of them is connected through a separation vessel filled with separation liquid with the lower and middle part of the measuring device below the expected level of the oil liquid. Another differential pressure gauge is connected through a diaphragm to the gas exhaust pipe to the manifold. The outputs of the differential pressure gauges are connected to the control unit. The claimed invention allows to measure the flow rate of the well not only for oil and produced water, but also
