Study on Mechanisms of Carbon Nanotube as a Nanosized Plugging Agent in Water Based Drilling Fluids
-
摘要: 针对微米级封堵材料无法对纳米孔缝进行有效封堵的问题，以微米级超细CaCO3作为对比，研究了氨基化多壁碳纳米管作为纳米封堵材料对钻井液流变参数的影响，通过人造泥饼滤失实验和人造岩心渗透实验研究了其封堵机理。研究结果表明，超细CaCO3使得钻井液的流变性能变差，而氨基化多壁碳纳米管对钻井液流变性能几乎没有影响；氨基化多壁碳纳米管对人造泥饼或人造岩心的封堵率随着其加量的增加而升高，当其加量为3%时封堵率可达77.70%和79.41%，而相同加量的超细CaCO3对人造泥饼的封堵率仅为45.28%和为61.76%。这充分说明纳米尺寸的封堵剂对纳米孔缝的封堵效果远优于微米封堵材料，碳酸钙只能在孔缝端面进行堆积，而氨基化多壁碳纳米管能够进入纳米孔缝形成架桥封堵，表面的氨基紧紧地吸附于孔缝的壁面上，阻止滤液的渗入。Abstract: Micron-scale plugging agents are unable to effectively plug the nanosized fractures. To overcome this problem, aminated multi-walled carbon nanotubes were selected as the nanosized plugging agent. The effects of the aminated multi-walled carbon nanotubes on the rheology of drilling fluids were studied using the micron-scale ultrafine CaCO3 as a comparison. The plugging mechanism of the aminated multi-walled carbon nanotubes was studied through filtration test on artificial mud cakes and osmosis experiment on artificial cores. The study results showed that the carbon nanotube has almost no effect on the rheological parameters of the drilling fluid, and addition of ultra-fine CaCO3 into the drilling fluid made its rheology deteriorated. Plugging of the artificial mud cakes with the aminated multi-walled carbon nanotube becomes improved with the increase in the amount of the nanotubes added. When the concentration of the aminated multi-walled carbon nanotube was 3%, 77.70% of the mud cakes can be plugged, while the addition of the same concentration of ultra-fine CaCO3 only plugged 45.28% of the artificial mud cakes. Experiment on artificial cores showed that at a concentration of 3% aminated multi-walled carbon nanotube, the core was plugged by 79.41%, while at a concentration of 3% ultra-fine CaCO3, the core was plugged only by 61.76%. These experimental results fully demonstrate that the nanosized plugging agents are much better than micron-scale plugging agents in terms of plugging; the calcium carbonate can only accumulate on the face of a fractured surface, while the aminated multi-walled carbon nanotube can penetrate into the nanosized fractures and form bridges therein. By tightly adsorbing on the surfaces inside the fractures with the amino groups, the aminated multi-walled carbon nanotube prevents the filtrate from going into the fractures.
