摘　　要：针对渤海油田油藏特点,以绥中36-1油田油藏条件为例,开展对环空封堵剂性能影响的分析及实验模拟。结果表明:对比30℃和50℃,绥中36-1油田油藏条件下(温度70℃)更有利于环空封堵剂有效地、快速地完成结构恢复;以绥中36-1油田油样为基础,在清洗剂预先清洗的作用下,驱替突破压力高于不使用清洗剂时的突破压力;以70℃和胶质沥青质为条件,清洗剂清洗后,实验模型下的环空封堵剂承压可达4 MPa·m^(-1),证明该环空封堵剂能够满足绥中36-1油田的油藏使用条件。According to reservoir characteristics of Bohai oilfield,taking the condition of Suizhong 36-1 oilfield reservoir as an example,the influence of reservoir condition on the annulus plugging agent performance was analyzed and experimentally simulated.The experimental results showed that,under the condition of Suizhong 36-1 oilfield reservoir(the temperature 70℃),the annulus plugging agent could more effectively and rapidly complete the structural recovery comparing with 30℃ and 50℃.The displacement breakthrough pressure based on the existing oil samples of Suizhong 36-1 oilfield and under the action of cleaning agent pre-cleaning,was higher than that without using cleaning agent.under the condition of 70℃ and gum-asphalt,the pressure bearing capacity of annulus plugging agent in experimental model reached 4 MPa·m^(-1) after cleaning with cleaning agent.The preliminary experiment shows that,the annulus plugging agent meets the requirements of the reservoir application condition of Suizhong 36-1 oilfield.
