| 摘 要： | 针对各向异性天然裂缝储层,蒙特卡洛随机模拟天然裂缝分布,从统计学角度表征天然裂缝参数,根据势叠加原理,把天然裂缝和人工裂缝当成独立的源进行势叠加,考虑天然裂缝和人工裂缝的耦合作用,建立压裂定向井稳态产量计算公式.计算结果表明,基于蒙特卡洛的天然裂缝模拟能从统计学角度反映产量变化趋势,能快速分析压裂定向井稳态产能.

| Abstract: | We focus on anisotropic reservoir with natural fractures,and simulate distribution of natural fracture with Monte Carlo. It characterizes natural fracture parameters from the perspective of statistics. Coupled natural and artificial fractures are considered as independent sources. A formula of steady production is derived according to potential superposition principle. It shows that Monte Carlo simulations of natural fractures reflect trends of productivity from a statistical point of view. It analyzes quickly steady productivity of fractured directional well. |
