钻孔冲洗液漏失是钻进中经常出现的一个孔内复杂问题。大部分地质岩心施工地区有漏失现象。有些地质队每年用于处理漏失的时间占钻探工作总台时的5~10%,漏失处理不当还会耗费大量的冲洗液和堵漏材料,使施工费用增加。因此,使用有效的技术方 Drilling Fluid Flushing Fluid loss is a complicated problem in a hole that often occurs during drilling. Most of the geological core construction area leakage phenomenon. Some geologic teams spend 5% to 10% of the total lost drilling time each year, which can cost a lot of flushing fluid and plugging materials due to improper handling. As a result, construction costs increase. Therefore, the use of effective technical side
