Experimental analysis indicates that petrophysical property , dynamic nature of rocks and stress field intensity of structural deformation are the main geologic factors controlling the fractural development in this area 结合实验分析认为，岩石特性、岩石本身的力学性质及构造变形应力场强度是控制其裂缝发育的主要地质因素。
The whole researching process of engineering geological feasibility is a step by step course from merely considering geological factors to taking the interaction between geological environment and engineering into account 整个高坝建设适宜性评价的过程是一个从仅仅考虑地质因素到综合考虑地质环境和工程相互作用的逐步深入过程。
The examination of the controls of the reservoir rocks indicates that the sedimentary microfacies and diagenesis are the principal geological factors controlling the development and distribution of the reservoir rocks in the study area 储层控制因素的综合分析认为，沉积微相和成岩作用是控制或影响该区储层发育与展布的主要地质因素。
At the late stage of oilfield development sedimentary microfacies in the reservoir is the major geologic factor controlling the remaining oil distribution , the reservoir physical property is poor between sandbodies , which determines the difference of reserves producing level 摘要油田开发后期，储层沉积微相是控制剩余油分布的主要地质因素之一，微相砂体间储层物性的差异，决定了储量动用程度的差别。
It is related to lithology , lithology association porosity , permeability , compressibility of rock , enclosing and fracture etc . therefore , it is important for the forecast of formation compression to consider fully the variation of each geology factor 实际上，地层压力的影响因素很复杂，与岩性及其组合、岩石的孔隙度及渗透率、压缩性、岩层的封闭性、裂缝等有关。因此，在进行地层压力预测时要充分考虑各种地质因素的变化。
In view of the petroleum geologic conditions and exploration degree of ordovician in tahe oilfield , three different methods such as pool size sequence , resources area abundance and geologic factor regression are selected for prediction / estimation of its potential resources 摘要针对塔河油田奥陶系石油地质条件和勘探程度，选用了油藏规模序列法、资源面积丰度法和地质因素回归法等三种不同方法，从不同的角度对奥陶系石油资源潜力进行估算。
From the aspect of the coupling action of geological and engineering conditions , this paper analyzes their influences on high slope stability . the result shows that constructional surface , lithology , slope angle and height are the most influential factors . provided that a slope angle in a stepped slope is constant , the slope stability is very sensitive to the height / width ratios of steps , and the best design for the slope is to make the height of each step no more than one - third of the total height and the height / width ratio between 1 : 0 . 2 - 0 . 3 从地质与工程耦合作用出发，分析了地质因素和工程条件对高边坡稳定性的影响，指出结构面、岩性以及坡角和坡高是边坡稳定性的重要影响因素，在边坡角一定的前提下台阶状边坡的台阶高宽比对边坡稳定性影响山十分明显，一般以每级台阶的高度不超过总坡高的1 / 3 ，高宽比在1 ： 0 . 2 0 . 3之间为最佳设计。
