摘　　要：文南油田是一个典型的高温高盐稀油油藏,目前已进入高含水期,主力油层已大面积水淹。为改善油田开发效果,研制了抗盐耐温颗粒调驱剂。室内的热稳定性、抗盐性能和膨胀速率实验表明,所研制的调驱剂能适应文南油田的地层特点,具有良好的耐温抗盐性。针对文南油田调驱的主要目的是挖掘主力油层剩余油潜力,确定了调驱区块的选择原则。在实施过程中,采用了水驱前缘监测和实时监测等工艺技术。Wennan Oilfield is a typical reservoir characterized by high temperature and high salinity. It is now in high water cut period, with water flooding already in the main formation. Particle profile control and displacement agents are developed to improve the oilfield development effect. The tests on heat stability, saltresistant capability and rate of expansion show that the profile control and displacement agents with a good performance of salt-tolerant and heat-resistant are suitable to the formation characteristics of Wennan Oilfield. Aimed at the main object of profile control and displacement which is to find and recover the residual oil, the principles for selecting profile control and displacement blocks are determined. Water drive front and real time monitoring technologies are adopted in the practical operation, and the relevant satisfactory results are obtained.
