摘要

研究了一种新型的抗盐胶态分散凝胶体系-抗盐CD胶 (ColloidalDispersionGels),它由非离子型聚丙烯酰胺 (浓度 80 0~15 0 0mg/L)、醋酸铬 (浓度 80~160mg/L)和甲醛 (2 0 0~4 0 0mg/L)等组成,具有抗盐性能好 (接近10 0 0 0 0万mg/L)、封堵效果佳的特点。现场试验 18井次,有效 16井次,取得了较好的应用效果。

Abstract

A new system of salt-resisting colloidal dispersion gels (CD gels) is researched and prepared. It contains nonionic polyacrylamide whose appropriate degree is from 800 mg/L to 1500 mg/L, acetic chromium whose appropriate degree is from 80 mg/L to 160 mg/L and formaldehyde whose degree is from 200 mg/L to 400 mg/L, etc. The CD gels have good salt-resisting and good water shutoff properties. Sixteen wells is efficacious within the eighteen field testing wells.Good effectiveness is acheved after field test.
