Abstract

With the increasing exploration of unconventional well, such as horizontal wells and complex wells, and the increasing strict national environmental protection regulations, the requirement for drilling fluids lubricants is more demanding. High-performance and environment-friendly lubricants for water-based drilling fluid are urgently needed. In this work, Chinese yam (Dioscorea opposutifolia L.) was investigated as a drilling fluid lubricant, the effects of Chinese yam slurry on drilling fluid lubricating properties at different temperatures were investigated, and the compatibility and inhibitory properties of Chinese yam slurry were studied. The results show that the viscosity coefficient of the mud cake is reduced by 44.5% as 1.5% Chinese yam slurryadded in water-based drilling fluids. Chinese yam also has certain temperature resistance in drilling fluids, and it can inhibit the swelling of clay. Chinese yam slurry is compatitive compatible with other drilling fluid additives, and the lubricity of modified drilling fluids can also be improved effectively. The lubrication mechanism of Chinese yam slurry was discussed through TGA, SEM, FTIR, and contact angle tests.

薯蓣作为水基钻井液绿色润滑剂的研究

随着水平井、复杂井等非常规井勘探的不断增加，以及国家环保法规的日益严格，对钻井液润滑油的要求也越来越高。水基钻井液迫切需要高性能、环保型的润滑油。本研究以山药(Dioscorea opopsutifolia L.)作为钻井液润滑剂，考察了不同温度下山药浆液对钻井液润滑性能的影响，并研究了山药浆液的相容性和抑制性能。结果表明:水基钻井液中加入1.5%山药浆，泥饼粘度系数降低44.5%;山药在钻井液中也有一定的耐温性，并能抑制粘土的膨胀。山药浆液与其他钻井液添加剂具有相容性，改性钻井液的润滑性也能得到有效改善。通过热重分析(TGA)、扫描电镜(SEM)、红外光谱(FTIR)和接触角测试，探讨了山药浆料的润滑机理。
