中文摘要: 论述了地应力驱动油气运移的机理,给出了地应力作用下孔隙地层中流体移动的本构方程和渗流方程。作为实例,模拟计算了胜利油田东营凹陷中央背斜带的地应力场和运移势场。结果表明,该背斜带已有的油藏分布与低应力区和低势区有很好的对应关系,大部分油藏位于低应力区和低势区,说明地应力对油气运聚成藏有重要控制作用。依据地应力场和运移势场的分布,对油藏的有利地区进行了预测,为油田的勘探开发提供了科学依据。
Abstract:Oil and gas migration mechanics driven by the crustal stress and constitutional equation and flowing equation are discussed in this paper. Take the Dongying depression of Shengli oil field as an example, this study models the crustal stress and migration potential field at the central zone of the anticline. The results show that the anticline has a well corresponding relation between oil and gas migration, and low stress zone or low potential zone. Most reservoirs occur in low stress zone or low potential zone, indicating the control of crustal stress over the migration and reservoiring of oil and gas. Based on the distribution of crustal stress and migration potential fields, the oil-favored areas predicted in this study will provide scientific guide for oil exploration and development.
