矿渣木素是利用亚硫酸纸浆废液和生产重铬酸钠的废渣为主配制的堵漏材料.它具有成本低、可灌性好、凝胶时间容易控制、凝胶体在水中有一定膨胀等优点.我队在东北工学院杜嘉鸿教授的指导和有关部门的大力协助下,于1978年对矿渣木素应用于钻孔堵漏进行了研究和生产试验.实践证明,矿渣木素用于不要求护壁,只要求堵漏的钻孔,是较为理想的.与目前所采用的其它堵漏材料相比,它还具有灌注所花辅助时间少的优点,一般从灌注到继续钻进只需2～3小时.现将试验情况介绍如下:
Slag lignin is the use of sulfurous acid pulp waste and production of sodium dichromate waste mainly formulated plugging material.It has the advantages of low cost, good irrigation, gel time easy to control, the gel body in the water has a certain expansion Etc. Our team conducted a research and production test on the application of slag lignin to drilling and plugging in 1978 under the guidance of Professor DU Jiahong from Northeastern University of Technology and the help of relevant departments.It has been proved that slag lignin Requires the protection of the wall, only requires plugging the hole, is more ideal than the current use of other plugging material, it also has the advantage of less perfusion assistance time, usually from perfusion to continue drilling only 2 ~ 3 hours. Now test the situation described below:
