This paper described lowest fracture reservoir structure, especially the micro fractures in rock mass starting from study ofcharacteristics of reservoir, it has very important significance for enhancing the result of developing the lowest permeabilityreservoir.

本文首先描述特低渗透储层的岩块及显裂缝系统及其特征，指出显裂缝系统大致由四组裂缝组成，长度大于2cm，渗流能力很强，约为岩块系统的1100倍；岩块系统包括基质和微缝部分，微缝一般长度小于2cm，规模小，包括岩块之内。

Firstly,the rock mass,macrofracture systems and their individual characteristics were described.

研究认为:岩块系统包括基质和微裂缝两部分,微裂缝一般长度小于200μm,规模小;两区块特低渗储层微裂缝呈条带状展布,且呈平行或雁式排列,具有明显的方向性,条带性随着岩性的变化而变化;可将微裂缝划分为有效缝和无效缝,有效缝对渗流起作用,无效缝充填方解石,对渗流不起作用。

It is very important to explain and testify the experimental phenomena of ultra-low friction,because the influence of ultra-low friction among rock mass is the main reflection of the dynamic characteristics of block rock mass.

超低摩擦实验效应则集中反映块系岩体动力特性的机制,对超低摩擦实验现象的解释与验证非常重要。

The effect of the lateral pressure on maximum load-bearing capacity of rock block investigated numerically, the relations between lateral pressure and the maximum load-bearing capacity are acquired, the acoustic emission rules of rock block with the change of lateral pressure are found out, which is practially beneficial for the research on t.

本文采用数值模拟方法研究了侧向压力对岩块极限承载能力的影响,得到了侧向压力与极限承载能力之间的函数关系,同时还找出了岩块声发射随着侧向压力的变化规律,这些问题的解决对于用数值模拟方法研究岩体工程的宏观力学性能无疑是很有意义的。
