摘要
岩体由岩块和结构面组成,结构面的发育程度对岩体渗流有至关重要的作用,完整的岩体基本不发生渗流,破碎岩体可以与土体一样视为多孔介质考虑。某地下水封油库库址区围岩强度等级较高,结构面多以节理裂隙发育为主,库址区岩体渗流主要受节理裂隙空间分布和裂隙形态参数影响。因此,要分析复杂裂隙岩体对地下水封油库岩体渗流影响,必须先研究库址区节理裂隙的方位角和连通性等发育特征。论文通过统计库址区岩体中的裂隙分布情况,总结了该区域裂隙的空间分布规律,该规律可用以预测库址区水幕系统的连通性,并对水幕系统的水封性作出评价。
The rock massiscomposed ofrock blocksand structural planes, the development level ofstructural plane playsan important role in the seepage of rock mass, the complete rock mass does not undergo seepage, broken rock bodies can be considered as porous media as soil. The strength of the surrounding rock in site area of a underground water-sealed oil storage is relatively high, and most of the structural planes are jointsand fissures, the seepage of the rock mass in the reservoir area is mainlyaffected bythe spatial distribution of the joints and fissures and the fissure parameters. Therefore, in order to analyze the seepage effect of complex fractured rock mass of underground water-sealed oil storage, it is necessary to study the azimuth angle and connectivity of joint fissures in reservoir site. Based on the statistical analysis of the distribution of fractures in the rock mass of the reservoir site, this paper summarizes the spatial distribution of fractures in this area. This rule can be used to predict the connectivityofthe water curtain system in the reservoir site area and evaluate the water seal ofthe water curtain system.
