Background
With the increasing demand of oil and gas resources in China and the environmental protection pressure and cost control, the water-based drilling fluid is a necessary development trend to replace the oil-based drilling fluid. However, in the actual exploitation process, especially in deep wells, ultra-deep wells and the like, the filtrate of the drilling fluid is very easy to cause well collapse and the like due to penetration into the stratum. Most of solid-phase particles in the existing drilling fluid are larger than nano-scale, and pores rich in nano-micro-scale are difficult to deposit to form an external mud cake, so that filtrate enters a stratum to cause well collapse. Thus, development of nano-plugging agents is a major and difficult point of water-based drilling fluids.
Nanomaterial is considered to be an effective nano-blocking agent because of its size effect, its particle size matches the nano-micron pore size. In recent years, nano silica, zirconia, graphene, and the like have been used as drilling fluid plugging agents. However, due to the complex stratum environment, the nano material is unstable in dispersion and easy to agglomerate in the stratum due to the conditions of electrolyte, high temperature and the like, so that the practical application of the nano plugging agent is limited. Therefore, the dispersion stability of the nano plugging agent is improved, the effective plugging of the nano-scale cracks is realized, and the method has important significance in keeping the well wall stable and reducing the underground complex accident rate.
