摘要
通过对福建煤田地层特征及其对钻探影响的分析,阐述了在福建煤田钻探中所遇的主要问题,结合实践论述了低固相泥浆的主要性能和优点、以及低固相泥浆对预防处理水敏性地层的缩径和破碎、松散等不稳定地层的坍塌、掉块现象具有的效果,对保证施工的顺利进行、提高施工质量与效率的重要作用。
By the analysis on the formation characteristics of Fujian coalfield and the influence to drilling,the paper presented the main problems in coalfield drilling;based on the practice,described the low solid mud about the main performance,advantages and the preventing effects to hole shrinking,breaking and collapsing and blocking in loose formation.
