摘　　要：苏北盆地高邮凹陷韦 5块稠油油藏是近年发现的普通Ⅰ、Ⅱ级稠油油藏 ,具有砂泥岩薄互层中、低渗特征。自投入开发以来 ,韦 5断块先后开展了蒸汽吞吐、酸化储层改造、微生物吞吐、高导短缝水力压裂、注常温改性水驱等多种矿场试验 ,取得了一定的成果与认识。本文重点介绍注常温改性水驱矿场试验情况 。The heavy oil reservoir of block Wei5 in Gaoyu sag of Subei basin, founded in the near years, was commen Ⅰ-Ⅱ rank heavy oil reservoir, which has the characteristics of sand-mud stone laminated zone and mid-low permeability. From plunging into development, various field trials have been carried in block Wei5, including cyclic steam stimulation, oil-bearing sand acidzing, microorganism stimulation, high conductibility and short gap hydraulic fracturing, ordinary temperature modification water injection, and we have got some effort and realization. The text put emphasis on the ordinary temperature modification water injection practice of the block Wei5 heavy oil reservoir. It will creat active guidance sense to the follow development operation of the block Wei5 and the same type reservoirs.
