Моделирование процессов гидроразрыва пласта для оптимизации добычи нефти: анализ неопределенностей

Abstract

В данной работе проведено построение секторной трехмерной геолого-геомеханической модели месторождения Х. Сделан акцент на таких явлениях как утечка жидкости ГРП и анализ влияния проницаемости пласта на свойства трещины по математической модели Картера. Описана методика построения 3D геомеханической модели с использованием данных исследований керна и геофизической исследований скважин. Проведена калибровка геомеханической модели. Проведена оценка прироста дебита для скважины с учетом смоделированного дизайна трещины ГРП методом виртуальных перфораций в гидродинамическом симуляторе. Полученная в рамках работы трехмерная геолого-геомеханическая модель дает представление о распределении упруго-прочностных свойствах горных пород и распределения напряженного состояния, а также может быть использована для проектирования моделей трещины ГРП.

In this paper the construction of sector 3D geological and geomechanical model of field X is carried out. The emphasis is made on such phenomena as leakage of hydraulic fracturing fluid and analysis of the influence of formation permeability on fracture properties by Carters mathematical model. The methodology of 3D geomechanical model construction using core and well geophysical survey data is described. Calibration of the geomechanical model was carried out. Estimation of flow rate increment for the well taking into account the modeled fracture design by the method of virtual perforations in the hydrodynamic simulator was carried out. The 3D geological-geomechanical model obtained in the framework of the work gives an idea of the distribution of elastic-strength properties of rocks and stress state distribution, and can be used for designing hydraulic fracturing.
