我队在大王矿区钻进，钻孔设计孔深都约1200米，钻机为XB－1000A型。孔深，地层复杂，超负荷施工，又使用不含处理剂的泥浆护孔，很难保证钻机正常运转。当使用栲胶泥浆后，基本上解决了上述问题，作到正常钻进。施工终孔的六个钻孔总进尺6663.76米，最深的达1160米，正在施工的两个钻孔已分别超过900和1000米。在超过千米之后，见矿最大厚度为70余米，为突破低缓异常打开了局面。通过生产实践，还初步掌握了针对不同地层使用不同配比的栲胶碱液处理泥浆的一些规律，现将有关情况简介如下。
My team in the king mine drilling, drilling hole depth of about 1,200 meters, rig XB-1000A type. Deep holes, stratigraphic complex, overload construction, but also the use of non-treatment agent mud hole, it is difficult to ensure the normal operation of drilling rig. When using glue slurry, basically solve the above problems, to make the normal drilling. The total footage of the six drilling holes in the final hole of the construction is 6663.76 meters, the deepest of which is 1160 meters. The two holes under construction have exceeded 900 and 1000 meters respectively. After more than one thousand meters, the maximum thickness of the mine was found to be more than 70 meters, opening up the situation for the breakthrough of low and abnormal anomaly. Through production practice, but also preliminary mastered the use of different strata of different strata of Trichosanthin treatment of mud some of the rules, the relevant briefings are as follows.
