Thermosetting resin gel plugging composition and preparation method thereof
The invention relates to the technical field of drilling fluid leaking stoppage, in particular to a thermosetting resin gel leaking stoppage composition and a preparation method thereof.The thermosetting resin gel leaking stoppage composition is prepared from G-grade cement, silica fume, floating beads, a fluid loss agent, a dispersing agent, thermosetting resin, a gel leaking stoppage agent, a coagulation accelerator, mixed fibers and water; a preparation method comprises the following steps: uniformly stirring required amounts of G-grade cement, silica fume, floating beads, a dispersant, a gel plugging agent, a coagulation accelerator and mixed fibers to obtain mixed powder, uniformly stirring required amounts of thermosetting resin, a fluid loss agent and water to obtain mixed liquid, pouring the mixed powder into the mixed liquid, and uniformly stirring to obtain the concrete. The thickening time of the thermosetting resin gel leaking stoppage composition is adjustable, the initial solidification time is 4-6 hours after the thermosetting resin gel leaking stoppage composition is mixed, solidification can be completed within 24 hours, the density is adjustable, and the compressive strength and the elastic modulus performance both meet the drilling requirements.
本发明涉及钻井液堵漏技术领域，是一种热固树脂凝胶堵漏组合物及其制备方法，前者包括G级水泥、微硅粉、漂珠、降失水剂、分散剂、热固性树脂、凝胶堵漏剂、促凝剂、混合纤维和水，按照下述方法得到：将所需量的G级水泥、微硅粉、漂珠、分散剂、凝胶堵漏剂、促凝剂和混合纤维搅拌均匀后，得到混合粉体，再将所需量的热固性树脂、降失水剂和水搅拌均匀后，得到混合液体，将混合粉体倒入混合液体中搅拌均匀后得到。本发明热固树脂凝胶堵漏组合物稠化时间可调，初始凝固时间在混配好的4h至6h以后，且能够在24h内完成凝固，密度可调，抗压强度和弹性模量性能均满足钻井要求。
