摘要： 为解决HV高强度凝胶堵水技术现场效果与室内性能评价存在差异等问题，以吴起区块延10油藏为例，提出了关井后管柱内动态压力对凝胶堵水效果的影响，并通过添加LCR促进剂优化出一种改进型HV高强度凝胶堵水体系，基于成胶时间、稳定性、动态压力及安全性能等进行实验评价。结果表明：快速成胶可以解决动态压力对凝胶稳定性产生的影响，同时优化得到了改进型HV高强度凝胶堵水体系，即为0.8%改性聚合物主剂+5.5%低聚酚醛树脂交联剂+0.03%助剂+0.012% LCR的促进剂，其成胶时间、成胶强度、老化稳定性、施工安全性均符合封堵要求和施工要求，并能在动态压力下保持稳定性和抗剪切作用。矿场试验后，取得了很好的增油降水效果，措施井降水最高达37.78%，平均日增油2.89 t，且有效期达9个月，取得了良好的堵水效果。

Abstract: In the light of the disparity for spot applied effects and laboratory evaluation of the HV high-strength gel plugging technology in Yan 10 reservoir in block Wuqi,the influence of dynamic pressure in the pipe string after closing the well on the effect of gel plugging was analyzed. A kind of modified HV high-strength gel water plugging system was optimized by adding fortifier agent LCR,and the properties were characterized by gelling time,gelling strength,ageing stability,the influence of dynamic pressure and safety. The results show that short gell time can overcome the influence of dynamic pressure on the stability. Besides,the modified HV highstrength gel water plugging system was composed by 0.8% modified polymer +5.5% cross-linking agent of oligomerization phenolic resin +0.03% accessory ingredient +0.012% fortifier of LCR. Gelling time,strength,ageing stability,and construction safety meet the requirements of plugging and well application,and the stability and resistance to shearing can keep constant with the dynamic pressure. Meanwhile,remarkable results of increasing oil and decreasing water have been given by field application and have produced very good effect. The measure well of application has reduced water content of 37.78% at most,increased output of oil about 2.89 t in average,and have been validly work up to 9 months.

Key words: gel, dynamic pressure, stability, resistance to shearing, field application, measure well
