摘要
以天然高分子松香为原料合成了一种油溶性的暂堵剂,并对其进行了油溶性、耐酸性、耐水性和分散性实验,确定了悬浮稳定剂的种类及最佳浓度.所研制的油溶性暂堵剂暂堵效果较好,在聚合物悬浮液中的暂堵率达93%以上,渗透率恢复值达85%以上,能对高含水油井实现选择性酸化,达到增油控水的目的,满足现场施工需要.
An ideal oil-soluble temporary plugging agent was synthesized from a natural macromolecular rosin, its solubility in diesel, acid resistance, water resistance and dispersivity were evaluated, and the type and concentration of suspension stabilizer determined. In a polymer suspension, the temporary plugging efficiency was more than 93%, and its permeability regeneration rate more than 85%, which demonstrates that the plugging agent meets the demands of selectively breaking down blocks in high water-containing oil-wells in order to increase oil production and control water content.
