摘　　要：低渗砂岩油藏裸眼井衰竭式开发引起地层能量快速衰减,产量递减快。注水吞吐通过渗吸作用,将注入水无法进入的小孔隙中的原油置换出来,改善地层原油的流动性,同时可以补充地层能量、有效消化污水。因此,在岳口油田开展注水吞吐采油实验,对注入介质、注入强度和交替周期等参数进行优化,并取得一定的增产效果。The depletion-drive development of open hole well in low permeability sandstone reservoirs causes the rapid decline of formation energy and production rate. Employing waterflooding huff and puff oil recovery technology can replace the oil in smaller pores, improve the flowability ofoil, supply the formation energy and improve the production of single well. Therefore the experiment on waterflooding huffand puff was carried out in Yuekou oilfield to optimize injected medium, injection intensity and injection period. And a certain production increase effect was obtained.
