Fluid loss additive base on Nano flexible polymer

摘要

In this paper, Nano-fluid loss additive was synthesized and characterized using Transmission Electron Microscopy (TEM) and the particle size analyzer. The TEM results have shown the formation of microspheres and the linkage of molecular polymer chains with hydrogen and ionic bonding. Particle size analysis indicated the presence of flexible Nano material in water and the stability of the Nano material in drilling fluid. The fluid property tests demonstrated that the filtration of Nano polymer was fairly good with the usage of common fluid loss agent. In addition, there was only a small change of filtration volumes before and after the administering of the aging test at 180°C, indicating high thermal stability.
