| 摘 要： | 室内油层岩心驱替实验研究结果表明，注水吞吐采油技术可发挥油层毛管力吸水排油作用，实现水驱，能有效地补充地层能量，恢复地层压力。通过多周期的注水吞吐开发，逐渐扩大水驱波厦半径，提高驱替效率。油层润湿性和渗透率是影响注水吞吐开发效果的主要因素。该技术简单易行，在头台油田实施后，效果十分显著，对同类油藏的开发真有指导意义。

| Abstract: | Core displacement experiment indicates that cyclic water injection can take advantage of the hydrophilic property of oil layer and the water-intake and oil-drainage mechanism of capillary pressure to realize waterflooding,complement formation energy,and restore formation pressure.Cyclic water injection development can expand sweep radius and enhance displacement efficiency.Reservoir wettability and permeability are the main factors affecting the development response.This technology is easily operative,has been used in Toutai Oilfield,and gained wonderful result.Other similar reservoirs can refer to this method. |
