高吸水树脂可用于油田调剖堵水,有机溶剂脱水及农田保水等。高吸水树脂凝胶中的水不易挤出。吸水凝胶的强度的岩芯测定法由于所取岩芯孔洞不均,测定结果重现性差。本文介绍一种测定吸水树脂凝胶抗压强度和抗压能的方法。 将凝胶置于压缩器中,用INSTRON-1121型材料试验机测定极限压强,以抗压强度σ表
Superabsorbents can be used in the oil profile control and water shutoff, organic solvent dehydration and farmland water conservation. Superabsorbent resin gel in the water is not easy to squeeze out. Determination of the strength of the water-absorbing gel core determination method due to uneven core hole taken, the determination of reproducibility is poor. This article describes a method for determining the compressive strength and compressive energy of water-absorbing resin gels. The gel is placed in the compressor, with INSTRON-1121-type material testing machine to determine the ultimate pressure, the compressive strength σ table
