近井带温度、压力和组分等条件的变化会导致原油中的胶质、沥青质等有机物在油层孔隙内部沉积 ,降低渗透率 ,造成近井带油层伤害 ,而利用注入有机溶剂浸泡来解除近井带有机污染是一种有效的方法。文中建立了一个利用有机溶剂吞吐解除油层有机伤害的数学模型 ,并进行了数值求解。同时 ,针对一个实例 ,模拟了溶剂注入速度、注入量、闷井时间对渗透率改善效果的影响 ,并对改善效果进行了预测。矿场应用结果表明 ,该方法效果较好 Changes in conditions such as temperature, pressure and composition near the wellbore can result in the deposition of organic matter, such as gums and asphaltenes, in the pores of the reservoir to reduce permeability and cause damage to the near-field zone reservoirs, and the use of organic solvent immersion to release Near-well organic pollution is an effective method. In this paper, a mathematical model for organic damage removal by organic solvent was established and numerically solved. In the meantime, for an example, the effect of solvent injection speed, injection amount and time of sinkhole on permeability improvement was simulated, and the improvement effect was predicted. The result of mine application shows that this method is effective
