Выполнен многопараметрический количественный анализ продуктивности горизонтальных скважин с многозонным гидравлическим разрывом пласта в режиме установившегося притока на основе высокоточного численного решения трехмерной задачи на подробной конечно-объемной сетке. Выявлены условия целесообразности выполнения многозонного гидроразрыва пласта и взаимосвязь основных параметров системы для достижения заданного уровня продуктивности скважины. Предложена аналитическая запись приближенного критерия, когда приток к стволу скважины пренебрежимо мал по сравнению с притоком к трещинам гидроразрыва. оценена точность и определены пределы применимости наиболее обоснованных упрощенных аналитических моделей расчета продуктивности.

A multi-parameter quantitative analysis of horizontal well productivity with multistage hydraulic fracturing under steady-state flow conditions was performed, based on a high-precision numerical solution of the 3D problem on a detailed finite-volume grid. The conditions justifying the application of multistage fracturing were identified along with the interrelationship of the main system parameters to achieve a target well productivity level. An analytical expression for an approximate criterion was proposed for the case when the inflow to the wellbore is negligible compared to that to the hydraulic fractures. The accuracy and limits of applicability of the most substantiated simplified analytical models for productivity calculation were evaluated.
