| description | Considering the fact that traditional cementing stone lacks toughness., post-production operations in oil wells often cause various forms of stress to cause cementing rings to produce micro-cracks or microcracks that are difficult to repair, which may affect cementing quality and long-term low durability. In response to the above problems, taking the cement slurry system as a starting point, a new type of epoxy resin emulsion modified slurry was prepared. The effects of resin emulsion at 0~20% dosage on the performance of cement slurry and its mechanical properties were studied and analyzed. The results show that when the content of resin emulsion is less than 15%, the bulk density of cement slurry is 1.88±0.04g/cm3 and the rheological properties of the slurry at 20~80°C are satisfied. Under the same temperature and pressure (80°C, 35MPa), the initial consistency can be controlled within 28Bc. The thickening time is 20~70% longer than pure cement, and the filtration loss of cement slurry can be obviously improved. Meanwhile, with the increase of the mixing ratio, the impact strength of the resin emulsion cement stone is increased by 15%, the elastic modulus is decreased by about 47.9%, and the toughness of cement stone is obviously improved. |
