以耐温磺化聚合物（ SPAM）、水溶性酚醛树脂、粉煤灰制备了适合于YT油田的高温封窜调堵剂。正交实验优选得到：0．3％SPAM、0．04％交联剂、5％粉煤灰的体系。温度、pH、矿化度对成胶效果的影响结果表明，100℃或更高温度对凝胶成胶不利；pH＝5时，成胶效果最好；矿化度增加不利于成胶，但当矿化度是50000 mg／L左右时，成胶黏度仍接近45000 mPa· s。耐温性测试结果表明，110℃高温老化20 d后，体系黏度有所降低，但体系仍能保证不脱水；热滚实验表明，凝胶的温度使用上限是150℃。岩心实验表明体系能够明显提高注气压力，减缓注气压降。

To block the gas channeling of high-temperature YT oilfield ,a gel plugging agent which is made up of sulfonated polymer (SPAM),water-soluble phenolic resin and ash had been prepared .The tests results of 0.3%SPAM,0.04%crosslinkers,5%fly-ash system and the temperature ,pH,and salinity influence on gelling show that:100℃and higher temperature is unfavorable on the gelation;the gelling is better when pH=5;Increased salinity is not conducive to gelling ,but when salinity is 50 000 mg/L or so,the gel viscos-ity is still close to 45 000 mPa· s.The results of temperature resistance showed that after 110℃high tem-perature aging 20 d,the gel viscosity decreased ,but the system is still no water separation;Hot rolling ex-periments showed that the upper temperature limit of the gel is 150 ℃.The core experience show that the gel can significantly improve the injection pressure and slow down the decrease of injection pressure .
