  • Publication number: 20210139764
    Abstract: The invention presents a high temperature-resistant and high oil-absorption resin particle plugging agent suitable for oil-based drilling fluid and its preparation method, wherein the plugging agent is prepared from raw materials in parts by mass as follows: 15-30 parts of reaction monomers, 5-12 parts of linear high polymers, 0.1-1.5 parts of cross-linking agents, 0.1-0.5 parts of initiators, 1-3 parts of modified starches, 1-5 parts of filler particles and 1-5 parts of dispersing agents. The resin particle plugging agent presented in the invention not only has high oil absorption capacity under a high-temperature condition, but also has high toughness after oil-absorbing expansion. It is not easy to break by extrusion and stretching and can effectively plug a high-temperature leakage passage. Also, the resin plugging particles in it will not be affected by crack factors.
