Abstract

Описаны способ и система оценки пластового давления в залежи углеводородов на основе данных измерений давления в добывающих скважинах. Данные измерений давления поступают из скважин на промысле в течение определенного периода времени и передаются на сервер, который использует указанные данные измерений скважинного давления в модели данной скважины. С помощью модели, работающей на сервере, в которой используются данные измерений скважинного давления, определяется рабочий режим скважины, например режим добычи или режим остановки. После определения изменения рабочего режима, сигнализирующего о резком изменении дебита скважины, например соответствующего событию остановки скважины, собираются данные дополнительных измерений скважинного давления до тех пор, пока не будет достигнуто установившееся состояние. Данные измерений давления используются для определения значения пластового давления, которое передается ответственному инженеру-промысловику или другому пользователю. Может быть принято изменение пользователем определенного ранее значения пластового давления, при этом сохраненное в запоминающем средстве значение пластового давления и модель скважины соответственно обновляются.A method and system for estimating reservoir pressure in a hydrocarbon reservoir based on data from pressure measurements in production wells are described. Pressure measurement data is received from the wells in the field for a certain period of time and transmitted to a server that uses the specified pressure measurement data in the model of this well. Using a server-based model that uses borehole pressure measurement data, the well’s operating mode, such as production mode or shutdown mode, is determined. After determining the change in the operating mode, indicating a sharp change in the flow rate of the well, for example, corresponding to the event of well shutdown, data are collected for additional measurements of the borehole pressure until a steady state is reached. Pressure measurement data is used to determine the value of reservoir pressure, which is transmitted to the responsible field engineer or other user. A user change of the previously determined formation pressure value may be accepted, wherein the reservoir pressure value and the well model stored in the storage medium are updated accordingly.
