Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.

In order to analyze rheological property and establish constitutive model of Q_2 loess, a series of uniaxial creep experiments on different water content are done .The creep test curves and stress-strain isochronism curves are drawed with the result of experiments and conclusions are reached from the curves. The creep performance of Q_2 loess is different under the different stress level. In the different time the stress-strain isochronism curve has obvious inflection point namely yield stress and the yield stress reduces along with the increase of water content, which can be described by exponential function.
为了分析黄土的流变特性和建立相应的本构模型,本文首先根据对不同含水量的Q_2黄土进行的一系列单轴应力条件的室内蠕变试验结果,分析总结了Q_2黄土蠕变特征和应力—应变等时曲线特征,得出Q_2黄土在不同的应力水平下蠕变变形表现形式不同;在不同的时刻应力—应变等时曲线存在有较明显的拐点,拐点所对应的应力即为屈服应力,屈服应力随着含水量的增大而呈指数形式降低;Q_2黄土可近似看成一种线性粘弹塑性体。
