В работе представлены результаты изменения или неравномерности проводимости (ширины, проницаемости или обоих профилей) в трещине. Это позволяет использовать этот метод для прогнозирования продуктивности и не только. Использование средней проводимости трещин для представления эквивалентного постоянного значения показало, что это хорошо работает для высокой проводимости, уменьшает проводимость эллипсоидальных или клиновидных трещин с максимальной проводимостью ствола скважины. Для перевернутых клиновых трещин (проводимость в скважине меньше среднего) эффективность трещины будет значительно снижена, а средняя проводимость значительно переоценит эффективное значение. Кроме того, для низкопроводимых трещин в скважине эквивалентная проводимость взвешивается больше в сторону максимальной проводимости скважины, чем к среднему значению. Также представлена оптимальная проводимость трещин (и их размеров) для заданного количества проппанта с целью максимизировать производительность.

The article presents the results of the variable or non-uniform conductivity (width, permeability or both profiles) in the fracture. This allows predict performance of damaged fracture, and so on. Usage the average conductivity of fractures to represent an equivalent constant value has shown that it works well for high conductivity, reduces conduction (i.e ellipsoidal or wedge-shaped fractures) with maximum conductivity in the wellbore. For inverted wedge cracks (conductivity in the well is less than an average) the fracture efficiency will be significantly reduced, and the average conductivity will greatly overestimate the effective value. Moreover, for low-conductivity fractures in the well the equivalent conductivity is weighed more relative to the value of the well than the average. Also the article presents the optimal conductivity of fractures (and fracture sizes) for a given amount of proppant to maximize productivity.
