深部调剖-驱油技术是提高油藏采收率的重要手段。首先从水窜关键问题分析及残余油高效驱替关键问 题分析两个方面，阐述了油藏深部调剖-驱油的两个主要矛盾：调剖剂注入性与油藏深部水窜通道封堵的矛盾以 及深部调剖与剩余油驱替的矛盾。重点综述了油藏深部调剖技术的原理以及在低渗透油藏中的研究应用，指出 了各技术的优势及存在问题，并分析了我国深部调剖-驱油技术发展趋势。

In-depth profile control and oil displacement technology is an important tool to improve the recovery rate of the oil reservoir. Through analysis of the key problems of water channeling and efficient displacement of residual oil，two major contradictions of in-depth profile control and oil displacement technology were explained from two aspects：the contradiction between the injectivity of the profile control agent and the blockage of the deep water breakthrough channels，and the contradiction between in-depth profile control and the displacement of remaining oil. In this paper，the principle of deep profile control technology and its application in low permeability reservoir were reviewed，the advantages and problems of each technology were pointed out，and the development trend of in-depth profile control and oil displacement technology in China was analyzed.
