When the shell layer of the asphalt particle is slightly melted, an optimizing liquid in the core layer of the asphalt particle can effectively increase the viscosity of the high polymer of the shell layer of the asphalt particle, the blocking effect of the asphalt particle on microcracks of the well wall is avoided, and the temperature use range of the high-softening-point asphalt particle is effectively expanded. The process is simple, easy to control and convenient to operate, the particle size of asphalt particles is small, the softening point is high, the microcrack blocking effect is good, and the market prospect is large.

Plugging agent for oil-based drilling fluid as well as preparation method and application of plugging agent
The invention discloses a plugging agent for oil-based drilling fluid. The plugging agent for the oil-based drilling fluid comprises the following components: 4-20 parts of a fiber material; 10-25 parts of a graphite material; 55-86 parts of high-elastic modified asphalt particles; wherein the high-elastic modified asphalt particle has a core-shell structure, and takes silica powder as a core and modified asphalt as a shell; the modified asphalt is composed of modified matrix asphalt, a modifier and a compatibilizer. The plugging agent for the oil-based drilling fluid is good in compatibility with the oil-based drilling fluid, high in plugging speed, high in high-temperature resistance and wide in adaptability to different sizes of leakage layer pores or cracks.
