sand-mudstone是什么意思

用法例句

But the resources of limestone as common material for building this rockfill dam are far from the dam site,and sand-mudstone is very abundant near the dam site.

董箐水电站大坝为面板堆石坝,但用作筑坝料较为成熟的灰岩料距坝址较远,而坝址处砂岩(夹泥岩)储量丰富,因此对砂泥岩进行了室内试验、现场爆破试验、现场碾压试验及坝体合理分区等的研究,解决了砂泥岩筑坝技术中的难题,为加快施工进度、节约工程投资创造了条件。

Porosity and permeability of sandstone near the sandstone-mudstone boundary is affected by the stacking pattern of sandstone and mudstone.

砂泥岩组合方式在不同埋深条件下影响了砂泥岩界面附近储层的物性。

In this paper, a new method called Integrated Evaluation Model is proposed, which uses sonic and other related well log data to evaluate pore pressure, that is, with giving consideration to the effect of clay content, porosity, vertical effective stress of shale sand formation on sonic velocity.

提出利用声波速度等测井资料检测地层孔隙压力的“综合解释方法” ,即同时考虑砂泥岩地层的泥质含量、孔隙度、垂直有效应力对声波速度的影响 ,先由相关测井资料求取泥质含量和孔隙度 ,再由声波速度计算垂直有效应力 ,最后通过有效应力计算地层孔隙压力。
