摘要(Abstract)：

概述了大庆油田近年来发展起来的胶态分散凝胶 (CDG)深度调剖技术的成胶机理、各种因素对CDG形成的影响、胶态分散凝胶渗流特征、驱油机理研究及现场试验效果。研究表明 ,CDG具有液流改向能力和流动性 ,聚驱后进行CDG调驱采收率可以提高 3 90 %～ 5 81% ,因而将其作为聚驱后进一步提高采收率的技术措施之一具有广阔应用前景
This paper introduces the gel generation mechanism, effect of various factors on CDG formation, colloid dispersal gel seepage characteristic and displacement mechanism of the depth profile control technique with colloid dispersal gel which is developed in Daqing Oil Field in recent years and the pilot test result. Core simulation experiment and numerical simulation experiment result shows that CDG has the capability of changing the fluid flow direction and flowing characteristic like polymer. CDG displacement controlling after polymer flooding can increase the recovery by 3 90%～ 5 81%.
