摘要
介绍了聚乙烯醇(PVA)和硼砂反应形成凝胶的机理,并通过对凝胶型堵漏剂PVA和硼砂室内试验的复配,确定了PVA凝胶型堵漏剂的最佳配方。根据实际漏失地层进行模拟测试,验证了凝胶堵漏剂在处理破碎地层的小裂隙、孔隙漏失等情况具有良好的效果。
The principles of the formation of the gel as reactions between polyvinyl alcohol（PVA）and borax are briefly introduced in this paper.The PVA gel can be potentially used as a sealing material for the leaking.The various mix designs of the PVA gel were laboratory tested and the optimized mix design was obtained.The field tests indicated that this material can be satisfactorily used in broken soils with small fissures.
