摘要
以胜利100号沥青为原料合成了改性COPNA树脂.改性COPNA树脂需要在COPNA树脂的侧链上接入含—Si(Oet)3基团的偶联剂分子,以使其比改性前对石英砂具有较强的亲和性、较高的热稳定性及抗压强度.试验考察了改性COPNA树脂的合成条件、溶解性、热稳定性和固砂性能等.实验中,选择"南大-42"为硅烷偶联剂,"COPNA树脂与偶联剂"的质量比例为"200∶0.5",于85～90℃温度下,搅拌反应6h,生成改性COPNA B树脂;以苯甲醛为固化剂,可使得改性COPNA树脂在400℃以下时,具有较高的热稳定性及抗压强度.试验表明,改性COPNA树脂可用作高温油井防砂材料和稠油热采防砂材料.
The modified condensed pdynuclear aromatic (COPNA) resin, which was made from Shengli No.100 asphalt and with —Si(Oet)_3 groups conjoined in side chain of COPNA resin, had high compressive strength with sands, high compressive strength and thermal stability. The reaction conditions and some properties such as solubility, thermal stability and sand consolidation were discussed according to the experiments. The modified COPNA resin, which was made from 'Nanda-42' silica-coupling and Shengli No.100 asphalt under the reaction temperature(85—90 ℃) and the reaction time(8 h) with COPNA resin/coupling mass ratio (200∶(0.5),) and benzoaldehyde as curing additive, had high compressive strength and thermal stability below 400 ℃. The modified COPNA resin can be used as the sand control agent in the high temperature oil well.
