随着油气田开发实践的不断进行,人们对油气藏的认识程度也不断深人.精细而精确的油气藏描述是做好油气田开发工作的基础,油气田开发实践又反过来促进油气藏描述工作向前发展.近些年来,一些新的方法和手段不断涌现,使得油气藏描述工作做得又快又好,在此基础上的油气田开发工作也更加科学化.本文主要介绍在油气藏描述和油气田开发过程中十分有用的一种新的介质模型——双重各向异性介质的发现及其渗透率数学模型的建立. With the continuous development of oil and gas fields, people’s understanding of oil and gas reservoirs has been deepening as well. The precise and accurate description of oil and gas reservoirs is the basis for the well development of oil and gas fields. In turn, oil and gas field development practices in turn promote the description of oil and gas reservoirs Development in recent years, some new methods and means are emerging, making the description of oil and gas reservoir done faster and better, based on which more oil and gas field development work is more scientific.This paper mainly describes in the reservoir description and oil and gas development A NEW MEDIUM MODEL WHICH IS USEFUL IN THE PROCESS - Discovery of Dual Anisotropic Media and Establishment of Mathematical Model for Its Permeability.
