陆梁油田头屯河组复杂油藏数值模拟研究

Numerical simulation study of complex reservoirs in Toutunhe formation of Luliang oilfield

针对陆梁油田头屯河组油藏幅度低、油层薄以及低孔、低渗等特点,应用油藏数值模拟技术,在历史拟合的基础上,确定了剩余油分布的有利区域,并针对影响油藏开发效果的天然能量、注采比、采油速度、井网适应性等不同方案进行了指标预测和优选。该项研究对改善油藏开发效果具有积极的指导意义。

Reservoirs in Toutunhe formation of Luliang oilfield are low amplitude,thin,low porosity and permeability.The favorable zones of residual oil distribution are determined by numerical simulation and history matching.Influence factors of development response,such as natural energy,injection-production ratio,oil recovery rate,and pattern adaptability are predicted and optimized.This study is of guiding significance to improving reservoir development response.
