摘　　要：杏南开发区进入特高含水期后,主力油层平面上已基本水淹,储层动用程度高,但由于层内非均质的影响,采出程度较低,为挖掘主力油层层内剩余油,开展了室内注粘土可行性研究。根据粘土调剖的机理,研究了粘土颗粒粒径与杏南开发区地层孔径的匹配关系,确定了适合杏南开发区调剖粘土注入浓度,优选了适合杏南开发区粘土调剖体系及合理用量,分析了非均质性对封堵量的影响,为杏南开发区挖潜主力油层层内剩余油,提高采收率将提供一种经济可行的调剖技术方法。The reservoir development in Xingnan development area has entered in the ultra-high water cut stage, the main reservoir plane has been flooded, reservoir producing degree is high, but due to the influence of layer heterogeneity, recovery degree is low. In order to exploit the remaining oil in the main oil layer, a feasibility study on clay injection was carried out. According to the mechanism of clay profile control, matching relationship between the clay particle size and formation pore in Xingnan development area was studied, suitable clay concentration in profile control of Xingnan development area was determined, clay profile control system in Xingnan development area was optimized as well as the reasonable amount, the impact of heterogeneity on the blocking volume was analyzed.
