basement rock meaning in Chinese
基底
基岩
Examples
- The strata of the region are divided into two structural layers : the basement rock consisting of metamorphic rock and cover layer of mesozoic and neozoic sedimentary rock .
将本区的地层划分为两个构造层：既变质岩系构成的基底构造层；中生代、新生代的沉积岩系构成的盖层构造层。 - Alone with progress of practice and the research of the petroleum exploration , especially the deepening of the research of basement rock pools exploration , these migration patterns need to be reconsidered
随著世界范围内油气勘探实戏的积累和油气形成与分布研究，特别是对基岩油气藏勘探研究的不断深入，上述运移途径需要重新加以认识。 - Another hidden danger is the weakening of the impervious ability of the dam resulting from the closeness of the height of line seepage of the reservoir water level to the contact plane between the residual solum , talus solum and basement rocks
水库水位浸润线标高和残坡积土与基岩接触界面标高较接近，而使此高程的防渗能力更加薄弱，这也是此坝体的隐患之一。 - The detection of hidden dangers in jinjiang reservoir dam with ground penetrating radar shows that the major hidden dangers of the dam are the karst caves in the dam basement rocks and the soil caves which were formed in the residual sola and talus sola by percolating channels such as faults and fissures
摘要在金江水库坝体隐患探测中，使用地质雷达发现坝体的主要隐患来自坝体基岩的溶洞和因断裂、裂隙等渗漏通道在残坡积土层中所成的土洞。 - When basement rock rupture pass through the well cross section , the fracture belts can be identified with some evidences , for example , the compensate neutron increasing and the stratum density diminishing synchronization , the dual - laterolog resistance diminishing greatly and the positive difference between the deep laterolog resistance and the shallow laterolog resistance appearing . when the compensate neutron increase , the stratum density diminishing and the dual - laterolog resistance value diminishing slightly , the fracture belts can be confirmed with the intrusive vein at high frequency in well cross section
当有基岩断裂在井削面上通过时，若补偿中子增大与地层密度变小同步发生，双侧向测井电阻率有明显变低并有正差异出现，则可以判别为裂缝发育带；当补偿中子增大，地层密度变小及双侧向幅度变小都不太明显时，则可以利用井剖面中频繁出现的侵入岩脉来确定裂缝发育段。
