近几年,一些研究地质勘探钻孔冲洗工艺的科技工作者提出,在冲洗液中加入一定数量的化学试剂,以增加冲洗液的各种性能,如在反循环冲洗液中加入一些具有多种性能的聚丙稀化学试剂。但有些化学试剂在化学工业上暂不能满足供应。为了适应钻进条件的多样性,所以就得采用来源比较方便的各种试剂。关于冲洗液的选择应考虑以下几方面:如钻进方法、地质构造、地下水的化学成份;也要考虑冲洗液的失水量等,目的在于提高钻进效率。
In recent years, some scientists who study the geological exploration drilling flush process proposed to add a certain amount of chemical reagents to the flush solution to increase the various properties of the flush solution, such as adding some Performance of polypropylene chemical reagents. However, some chemical reagents in the chemical industry temporarily unable to meet the supply. In order to adapt to the diversity of drilling conditions, so you have to use more convenient source of various reagents. On the choice of flushing fluid should consider the following aspects: such as drilling methods, geological structure, groundwater chemical composition; also consider the loss of flushing fluid, the purpose is to improve drilling efficiency.
