摘　　要：本文主要对高盐油藏聚合物调驱剂进行筛选,并评价其相应适应性。分别配制超高分子量抗盐聚合物:(1)微交联抗盐聚合物;(2)抗盐聚合物;(3)弱凝胶溶液,对高盐油藏聚合物调驱剂性能进行分析。研究结果表明,采用软化水配制聚合物溶液且压力在0.4~0.8 MPa范围内效果最好。聚合物调驱剂在高盐环境下具有较好的稳定性和调驱效果,有效地改善高盐油藏的采收率。本研究为高盐油藏的调驱剂筛选和应用提供了重要参考。This paper focuses on the screening of polymer mobilizers for high-salt reservoirs and evaluates their corresponding adaptability.Ultra-high molecular weight anti-salt polymer(1)micro-crosslinked anti-salt polymer(2)anti-salt polymer and(3)weak gel solutions were prepared to analyze the performance of polymer conditioners in high-salt reservoirs.The results of the study showed that the best effect was achieved by using softened water to formulate the polymer solutions and the pressure was in the range of 0.4~0.8 MPa.The polymer conditioning agent has good stability and conditioning effect in high salt environment,which can effectively improve the recovery rate of high salt reservoirs.This study provides an important reference for the screening and application of driving agents in high-salt reservoirs.
