The physical properties are mainly dominated by thress factors : solution , sedimentary facies and buried depth 主要发育次生孔隙,储层物性受溶蚀作用、沉积相、埋藏深度三个因素的控制。
Formation causal analysis and foundation strength discussion on dissoluble soft intercalation in rock foundation of a project 某工程岩石地基中溶蚀软弱夹层形成原因分析及地基强度探讨
The lay - like karst aquifer formed by some special strata and fossil karst are very important in the groundwater exploitation in this area 特殊岩性和古溶蚀形成的似层状岩溶含水层具有重要的开发价值。
Because of long - time water erosion and weathering , the furface of the stone becomes uneven , looking like a rough sea 由于长年被水流冲蚀溶蚀及风化作用,使岩石表面凸凹不平,如同风吹过水面,卷起千层浪。
Montmorillonite , quartz and cristobalite can be corroded by sodium hydroxide solution , but will introduce new impurity phase similar to zeolite 氢氧化钠溶蚀法会对蒙脱石、石英和方石英同时产生溶蚀,引入新的物相杂质。
Dissolition is favorable for secondary porosity , thus forming available reservoirs in some sections of low porous and low permeable clastic rocks 从而使某些砂岩段在低孔低渗储层中形成较发育的次生溶蚀孔隙和成岩微裂缝,并成为有效孔隙。
The karst groundwater stores in the shallow karst zones below the surface , the middle karst zones controlled by geological structures and the deep zones of fossil karst 岩溶地下水赋存于地表以下浅部岩溶带、构造控制的中部岩溶带和深部古溶蚀带。
Besides lithological characters and geological structures , the karst development and groundwater in the area are affected by neotectonic movement and fossil karst 区内岩溶发育和地下水赋存除受岩性、地质构造的控制外,还受新构造运动和古溶蚀的影响。
Test of carbonate rock sample ' s dissolution reveals that lithology ' s effects on dissolution mainly lie on their different start - up dissolution velocities 摘要对碳酸盐岩类岩石样品的溶蚀试验表明,岩性对溶蚀的影响主要表现为各类岩石在启动溶蚀速率上的差异。
In the same conditions of temperature , pressure and specific surface area , the start - up dissolution velocity of limestone sample is more than the dolostone ' s one 在相同温压、相同比表面积的条件下,灰岩类岩石样品的启动溶蚀速率大于白云岩类岩石样品的启动溶蚀速率。
