摘要
元城富县油藏部分井呈现储层堵塞特征,开展了解堵措施治理效果不理想,急需开展储层堵塞机理研究,明确堵塞原因,为下步堵塞井治理及预防堵塞提供技术指导。为此开展了粘土矿物分析、敏感性分析、流动伤害实验及配伍性分析等。研究表明:配伍性差,流动伤害导致结垢堵塞孔喉是储层堵塞的主要原因,结垢主要为碳酸钙垢。
Some wells in Fuxian Reservoir of Yuancheng show the characteristics of reservoir plugging,and the effect of understanding the plugging measures is not ideal It is urgent to carry out research on the mechanism of reservoir plugging,and identify the reasons for plugging,so as to provide technical guidance for the next step of plugging well treatment and prevention.Therefore,clay mineral analysis,sensitivity analysis,flow damage experiment and compatibility analysis were carried out.The research shows that poor compatibility,scaling and plugging of pores and throats caused by flow damage are the main reasons for reservoir plugging,and the scaling is mainly calcium carbonate scale.
