Horizontal well production forecasting formulas need to consider not only anisotropism and borehole eccentricity , but also the skin factor during drilling and completion process 摘要水平井产能预测公式除了要考虑储层各向异性和井眼偏心距的影响因素外，还要考虑钻井和完井过程中产生的表皮系数的影响。

Because the anisotropism of the reservoir is severeness , there are no nature gapping , the reserves abundance is low and the well has no nature off - take potentia , this gas pool is a low permeability , low abundance , deadly low production , low grade complex pool 因储层非均质性严重，无天然气裂缝，储量丰度低，气井无自然产能，又属于低渗低丰度，特低产、低品位复杂气藏。

The actual condition of xac are studied , the characteristic of most kinds of methods of stretch - wrap forming are analyzed and the evaluating method of anisotropism of extrusion are summarized , therefore parameters about anisotropism of extrusion are obtained according to series of experiments 从西飞公司钣金加工的实际情况入手，分析了各种型材拉弯方法的特点，研究了挤压型材各向异性的评价指标，并利用实验获得了挤压型材的各向异性参数。

Based on the previous and through the uniaxial tension damage experiment and comparing to the uniaxial compression damage experiment , the paper makes research on the anisotropism of the damage and the difference of the damage between the uniaxial tension and the uniaxial compression , combining with orthogonal anistropic damage model and exponent function damage developing equation . through the formulae deduction , the damages caused by the same absolute value tension and compression strain have the comparing character in some extent and corresponding decay coefficient 本文在前人研究的基础上，通过单轴拉伸损伤试验，及其与单轴压缩损伤试验的比较，进一步结合正交异性损伤模型与指数函数损伤演变方程，对混凝土体中损伤的各向异性以及单轴拉伸和单轴压缩情况下损伤的差异性进行了研究探讨，经过公式推导，提出绝对值相等的拉、压应变产生的损伤具有一定的可比性，并给出了进行可比性换算的折减系数。

In view of the main feature of strong anisotropism of reservoir stratum of the paleozoic era carbonate rock in the middle part of ortos basin gas field , mainly by means of random analog formation , this paper makes a quantitative tranformation on the geological study on the area and the descriptive results of the gas pool , and finishes the whole geological model of underground carbonate rock in ortos basin , including the structure model / phy - sical model and fluid distribution model 摘要针对鄂尔多斯盆地中部气田下古碳酸盐岩储层非均质性强的主要矛盾，以随机模拟建摸为主要方法，对该区地质研究和气藏描述成果进行定量化转变，形成了包括构造模型、物性模型和流体分布模型的鄂尔多斯盆地下古碳酸盐岩整体地质模型。
