The invention discloses an anticollision component as well as the preparation method and the usage thereof. Particularly, the anticollision component is formed by splicing a composite structure that polypropylene resin is soaked in a carbon fiber. The preparation method of the anticollision component comprises the following steps: (a) forming a presoaked sheet; (b) forming stacked presoaked sheets subjected to shearing and cutting; (c) forming a composite board; and (d) forming the anticollision component. The anticollision component and the preparation method have the advantages that the weight is light, energy is saved, environment is protected, large batch continuous automatic production can be achieved, and the forming efficiency is high.

Anticollision component as well as preparation method and usage thereof

After tertiary recovery from the oilfields, improving the production of the remaining hydrocarbon is always challenging. To significantly improve oil recovery, a heterogeneous composite flooding system has been developed with preformed particle gels (PPG) and polymers according to the technical approach of plugging and flooding combination. In addition, an oil saturation monitoring device and a large-scale 3D physical model were designed to better evaluate the performance of the technique. The evaluation results show that the viscosity, stability, and elasticity of the heterogeneous composite flooding system are better than the single polymer system. In addition, both systems exhibit pseudoplastic fluid characteristics and follow the principle of shear thinning. The results of seepage experiments showed that PPG migrates alternately in porous media in the manner of “piling plugging-pressure increasing-deformation migration”. The heterogeneous composite system can migrate to the depths of the oil layer, which improves the injection profile. In the visualization experiment, the heterogeneous composite system preferentially flowed into the high-permeability layer, which increased the seepage resistance and forced the subsequent fluid to flow into the medium and low permeability layers. The average saturation of the high, medium, and low permeability layers decreased by 4.74%, 9.51%, and 17.12%, respectively, and the recovery factor was further improved by 13.56% after the polymer flooding.
