微粒运移损害宏观规律研究

1．流体动力引起的微粒运移 Guesbeck和Collins通过流动试验发现，对一定的砂岩储层存在一定的临界流速虬，当润湿相流体的流速大于此值时便引起微粒运移损害。一般砂岩储层的临界流速为0．004～0．25cm／s．Berea砂岩的临界流速为0．007cm／s。

Review of Daqing＇s Technologies in 10th Five-Year Plan Period

During the 10^th Five-Year Plan Period, Daqing Oil Field entered the late high water-cut period with the reserve production ratio in imbalance. The oil field development became more and more difficult owing to the inadequate substitute resources. Daqing Oil Field Company has made a series of important and new technological achievements to solve those bottlenecks. The oil field has cumulatively achieved a total of technological results, of which eight items are at the State level, 96 items at the provincial and ministerial level, and 1009 items granted with the patent rights. The oil field has developed a family of exploration and development technologies which are world-leading and self-developed with an independent IPR.
