介绍了园林绿地与硬地铺装之间的6种交接方式,提出了合理利用地形和合理选用材料以协调两者之间的关系。
2) hard and brittle strata
硬脆地层
1.
During the geothermal well drilling,to encounter of hard and brittle strata is very often,especially the Jurassic andesite and tuffs.
在地热井施工过程中,经常钻遇硬脆地层,特别是侏罗系安山岩、凝灰岩地层,钻进过程中产生严重跳钻现象,个别地层还产生H2S气侵,造成钻铤频繁断裂。
4) hard formation
硬地层
1.
Design of PDC bit for hard formation;
硬地层PDC钻头设计的探讨
2.
PDC bits are generally inadaptable for drilling hard formation,especially for the gravel layer with high compressive strength and abrasion.
PDC钻头不适宜钻硬地层,尤其是高强度、高研磨性的砾石层,因为在极其恶劣的工作条件下,PDC齿的冲击破损严重,热磨损及磨料磨损往往同时存在,齿的磨损速度快,钻头的工作寿命急剧缩短。
