研究各种类型的凝胶降低水和气在多孔岩石中渗透率的原因。共使用五种类型的凝胶：①“弱”的间苯二酚-甲醛凝胶。②“强”的洞苯二酚-甲醛凝胶；③Cr（Ⅲ）-黄原胶凝胶；④Cr（Ⅲ）-乙酸酯-聚丙烯酰胺凝胶；⑤胶质氧化硅凝胶。用这几种凝胶进行了强化岩芯驱替试检，以便评估其降低渗透率的性能及其对于重复水、气交替注入周期的稳定作用。试验是在900lb／in2和1500lb／in2压力下进行的，后氮气或二氧化碳作为压缩气体。研制了一种岩芯驱零星仪，上面装有高压分光光度计，可使实验进行时岩芯压力不下降。还做了凝胶对油和水渗透率影响的平行实验，把二者相似之处记录下来。
The reason why various types of gels reduce the permeability of water and gas in porous rocks is investigated. Five types of gels are used: ① “Weak” resorcinol-formaldehyde gel. ② “strong” catechol - formaldehyde gel; ③ Cr (Ⅲ) - xanthan gum; ④ Cr (Ⅲ) - acetate - polyacrylamide gel; ⑤ colloidal silica gel. Reinforced core-displacement tests were conducted with these gels to assess their permeability-reducing properties and their stabilizing effect on the cycle of repeated injections of water and gas. The tests were carried out at pressures of 900 lb / in2 and 1500 lb / in2 with nitrogen or carbon dioxide as the compressed gas. Developed a core flooding sporadic instrument, equipped with high-pressure spectrophotometer, the core pressure can be carried out when the experiment did not decline. Parallel experiments were also conducted on the effect of gels on oil and water permeability, and their similarities were recorded.
