中文摘要:在甘肃省山丹县花草滩煤矿扩大区煤炭详查钻探施工中,普遍存在着泥岩地层造浆、膨胀缩径及坍塌掉块等问题。针对上述问题,开展了钻井液工艺研究,选择了有机硅抑制剂、降滤失材料、随钻封堵材料及包被絮凝材料,进行钻井液配方及性能研究。通过室内实验及现场应用,证明了该钻井液具有良好的抑制性能、防塌护壁性能及流变性能,有效解决了上述技术难题,钻井液使用周期大幅提升,显著减少了废弃钻井液的排放,促进了绿色勘查理念在勘查区的实践推广。

Drilling fluid technology and application in detailed coal explorationin the extended area of Huacaotan Coal Mine, Shandan, Gansu
Abstract:During detailed coal exploration drilling in the extended area of Huacaotan Coal Mine, Shandan, Gansu, problems such as mud production, borehole expansion or shrinkage, caving and falling blocks in mudstone formation were often encountered. In light of the above problems, drilling fluid technology research was carried out. Materials as silicone inhibitor, filtrate reducer, plugging while drilling materials, and coating and flocculation materials were chosen for research on drilling fluid formulation and properties. Through indoor experiments and field applications, it has been proved that the drilling fluid has good inhibiting performance, anti caving and wall protection performance and rheological properties, and effectively solves the above technical problems. The service period of the drilling fluid is greatly increased; thus significantly reducing the discharge of waste drilling fluid, and fostering the application of the concept of green exploration in the exploration area.
