摘　　要：前言双河油田是我国高效开发的陆上油田之一，其４３８断块Ⅲ３油层开发效果尤为突出，目前采出程度超过５１％，水驱采收率超过６０％，（双河油田经济极限水驱油效率较高，为５１．８８％～６４．８％，该单元的地质储量计算经过多年的核实，应该比较准确。）这在全国并...High production rate and high benefit development modes are revealed through analysis of the geological features, development status, well pattern structures and important adjustment and their effects during developing Zone Ⅲ 3 of Fault Block 438 in the Shuanghe oil field, which include: artificially supplementing energy early can keep high production rate in thick layers in small fault blocks due to their low elastic energy, improving injection and production pattern and implementing internal and peripheral irregular spot flooding pattern can keep reserves not outflowing and raise the producing ratio of unit reserve, subdividing layers and seepage unit in a layer are effective ways to solve vertical interference, seizing the opportune moment to carry out balanced injection and enhanced injection and recovery is the main method to raise producing rate, layer regrouping is the main act to fully tap plane potential.
