我分队广大职工在大队党委和分队党支部的正确领导下，深入开展“工业学大庆”的群众运动，从路线教育入手，狠抓生产中的薄弱环节，用铁铬盐泥浆突破了忙牛海超基性岩钻进中的护孔难关，消灭了半截孔。促进了效率与质量的提高，加速了铬矿普查工作。此超基性岩体受东西、南北～北北东向构造控制。超基性岩全部蛇纹石化和碳酸盐化。因此，松软破碎，岩石层本身造浆性强。24秒的新泥浆反上来就成泡沫状，不流动，比重减轻到一以下，岩体上下围岩和脉岩也有强烈的碳酸盐化，加之后期岩脉侵入岩体，受后期构造影响，使岩层松软破碎，软硬互层，地层很不稳定，不但岩心难采取，而且给
With the correct leadership of the brigade party committees and the detachment party branches, the majority of our workers and their staff carried out the mass movement of “Daqing in Industry”, starting with the line education and paying close attention to the weak links in production. Rock drilling difficult to pass in the hole, eliminating the half hole. Promoted the improvement of efficiency and quality, and accelerated the general survey of chrome ore. This ultrabasic rock is controlled by east-west, north-south-north-north-east structures. All of the ultrabasic rocks are serpentine and carbonate. Therefore, soft and broken, the rock layer itself strong pulp. 24 seconds of the new mud turned up into a foam-like, do not flow, the proportion reduced to a below the rock body rocks and veins also have strong carbonation, combined with the late dikes intrusion rock, affected by the late structure, So that the rock soft broken, hard and soft interbedded stratum is very unstable, not only hard to take, but also to
