摘要
由于地质上的原因,储油气层岩石往往表现出渗透率的各向异性,正确认识渗透率的各向异性是油气田勘探与开发中的一项基础工作。根据改进的全岩心分析装置的测试数据,建立了描述流体在各向异性介质中三维不稳定渗流的数学模型和计算各向异性储油气层岩石渗透率张量的自动拟合模型,并采用逐步二次规划法进行了求解,从而为室内测量和解释各向异性岩心渗透率张量提供了可行的方法。最后,通过算例说明了方法的可行性和可靠性。
Reservoir permeability is of anisotropy from complicated geologic structure, hence the study for anisotropy of rock permeability plays a key role in exploring and developing oil and/or gas field. On the basis of test data from whole core analysis device in laboratory, this paper establishes a mathematical model about three-dimensional unsteady flow in anisotropic porous medium as well as an auto-matching model about calculation of anisotropic rock permeability which is solved by sequential quadratic programming methods. Examples are given which show this research is valuable.
