| 中文摘要:云南省曲靖市罗平县红丫口煤矿勘探项目临近大断裂带，受多期构造地质作用影响，走向逆断层发育，且发育有横向平移断层和少量正断层。地层受挤压变形严重，岩层倾角普遍较大，局部直立至倒转，地层破碎。上部漏水严重，下部钻遇多条断层破碎带以及煤系地层，造成钻进效率低下，钻孔事故频繁，甚至钻孔报废，严重影响勘查工作的顺利进行。针对这一系列的施工难题，经过多次研究和反复试验，探索出一种适合该矿区煤矿勘察复杂地层钻进的泥浆，保障了勘查项目的顺利完成。 |

| Abstract:Hongyakou coal exploration project in Luoping County of Yunnan Province is located near the fault zone. Influenced by multiphase tectonic geological processes, parallel thrusts, lateral strike-slip faults and a small amount of normal faults developed. There are serious deformations by extrusion, large strata inclination and even with local upright to inverted and broken strata. According to the low drilling efficiency and frequent accidents caused by severe upper leakage and drilling to the fault fracture zones and coal-bearing strata, the researches and tests were made to explore the mud suitable for complex strata drilling of coal exploration in this coal mine. |
