具有护壁作用的无固相冲洗液的研究与应用,对发展金刚石钻进、孔底动力钻具钻进和水井钻进等都有重大意义.碱处理MY-1型无固相冲洗液,具有低失水及稳定孔壁等良好性能,在我国许多地质队的初步应用,已取得一定的效果;但它仍然存在加碱后粘度降低,不能满足钻进一些无胶结的破碎岩层的要求.为此,我院进 The research and application of solid-free rinsing liquid with protective wall have great significance for the development of diamond drilling, bottom hole power drilling and water well drilling, etc. Alkali-treatment MY-1 solid-free rinsing liquid has Low loss of water and stable pore wall and other good performance, the initial application of many geological teams in our country, has achieved some results; but it still exists in the alkali viscosity decreased, can not meet the requirements of drilling some non-cemented broken rock. This, my hospital into
