| 摘 要： | 南阳板厂多金属矿区地质情况复杂，上部地层裂隙发育而导致井漏普遍发生；中部地层绿帘石及绿泥石水敏性强，易发生垮塌、缩径。确定上部使用低固相植物胶泥浆体系，并通过试验明确了植物胶、腐植酸钾及聚丙烯酸钾的大致加量及其对泥浆性能的影响规律；中下部在植物胶泥浆的基础上转为钙处理泥浆以增强抑制性，适当增加植物胶(CL)和沥青粉(FT)的加量以增强泥浆的胶结能力与封堵能力。上述泥浆方案在板厂矿区ZK1724钻孔中获得了成功应用，为该矿区复杂地层钻进施工创造了有利条件。

| Abstract: | The geological situation is complicated in Banchang polymetallic mining area. The fracture development of the upper part leads to the common occurrence of well leakage, collapse and shrinkage often occur because of strong water-sensitive of epidote and chlorite in middle formation. It is determined to use low solid plant glue drilling mud system in upper part; and the approximate adding amouts of plant glue, potassium humate and potassium polyacrylate as well as the influence on drilling mud performance are made clear by series of experiments; at the lower part, on the basis of plant glue, calcium treatment drilling mud was used to enhance the inhibition, increase adding amount of plant glue(CL) and asphalt powder(FT) in order to improve cementing ability and sealing ability of mud. The mud schemes have been succssefully applied in ZK1724 of Banchang polymentallic mining area, which created favorable conditions for complex formations in this area. |
