摘要
桦南城西勘探区在钻探施工过程中易出现孔壁坍塌、缩径现象而且岩粉颗粒大、含量高,给施工带来很大困难,通过使用石油钻井助剂FT-99及其它助剂配制的优质泥浆,有效地提高了钻进效率,避免了孔内事故,达到一次成孔的目的。
The HuaNan explores the area easy appear the bore wall to collapse to fall in drill explore start construction process, the path of shrink and the rock powder grains axe big, the content is high, giving start construction to bring very difficult, pass to use the petroleum artesian well to help a FT - 99 and other help to install the high - quality mud, raise to drill into the efficiency availably, avoid the trouble inside the bore, attain once purpose of become the bore.
