| 摘 要： | 针对低渗透油藏非线性渗流理论与数值模拟方法方面存在的大量问题,从毛细管模型出发,推导了低渗透油藏非线性渗流新模型,详细解释了新模型中特有的物理参数内涵;并由此建立了低渗透油藏非线性单相渗流理论,与相对渗透率引入渠道流假设一致,将单相非线性新模型推广到两相渗流中,建立了能够同时考虑启动压力梯度、非线性渗流弯曲段连续变化的数值模拟方法。根据所建立的低渗透油藏单相稳态和非稳态渗流理论以及数值模拟方法,开展了达西、拟启动压力梯度和非线性模型的油藏动态对比计算。结果表明:低渗透油藏主要受非线性渗流控制,仅井点的少数网格存在拟线性流动,非线性模型计算的结果介于达西和拟启动线性模型之间。 |

| Abstract: | There are still many issues which need to be worked out in research of nonlinear flow in low permeability reservoirs.For this reason,a new flow model was deduced in view of the caplillary model.Meanwhile,the denotation of parameters in the new model was explained detailedly.On the basis of the new model,theroy of single phase flow in low permeability reservoirs was set up.The single-phase model was introduced into two-phase flow on the basis of the theory of channel flow.According to the theory above,numeri... |
