摘要
针对齐2-8-10块杜家台油层目前的开发情况,提出了利用一种可以改变岩石表面性质、降低原油与岩石表面作用力的分子膜剂做为驱油剂的技术对策,通过室内模拟实验表明该分子膜驱油剂可在水驱后进一步提高驱油效率6%左右,且能降低含水率及注入压力。现场在7口注水井分两个阶段共注入分子膜驱油剂74.55 t,在统计期内周围21口油井有17口井见到了增油降水1 847 t,综合含水下降了1.2%,取得了非常好的驱油效果。
In this paper,based on the current development of the Dujiatai oil layer in the Qi 2-8-10 block,a technique is proposed for using the molecular film agent which can change the surface property of rock and reduce the force of oil and rock surface acting as oil displacing agent.The results of laboratory simulation show that the oil displacement agent can further improve the oil displacement efficiency by about 6%after water flooding,and can reduce the water content and injection pressure.At the same time,17 wells of 21 wells in the surrounding area were observed.The total water cut decreased by 1.2%,and achieved very good results.
