Целью работы является разработка метода для определения градиента давления гранулированного геля PPG для блокирования техногенных трещин (трещин автоГРП), который используется на поздних стадиях разработки нефтяных месторождений. На лабораторной модели трещины были получены значения констант (кажущейся постоянной консистенции и кажущегося показателя псевдопластичности) для уравнения вязкопластичной жидкости. Эти же константы использованы в полученном уравнении для градиента давления вдоль техногенной трещины. Градиент давления геля рассчитывался из уравнения движения геля вдоль трещины. Данное уравнение позволяет рассчитывать градиент давления для каждого размера фракций гранулированного геля в зависимости от ширины трещины и скорости закачки геля.

The ultimate goal of this paper is to develop a method to to determine the pelletized gel pressure gradient, PPG, in fractures resulted from FHF applied at later stages of oil fields development. Using the laboratory fracture model the values of constants (apparent constant of consistency and apparent index of pseudoductility) for viscoplastic fluid equation were obtained. These constants were also used in the derived equation for pressure gradient along the induced fracture. The gel pressure gradient was calculated by the equation of gel movement along the fracture. This equation enables to calculate the pressure gradient for each size of pelletized gel granules depending on the fracture width and the gel injection rate.
