摘要
In east China, almost all the old fields have stepped into high water cut stage, with main development blocks into phase of super high water\|cut and high ratio of total oil produced to OOIP. Because of the complicated distribution of remaining oil and great difficulties of potential excavation, effective succeed development methods are in urgent. Through physical modeling in lab, field experiments and industrial deployment, a set of necessary industrialized technology is posted, which is suitable for terrestrial fluvial delta reservoirs during super high water bearing stage, including the detailed description of major reservoir, remaining oil monitoring, fine potential exploitation by water flooding and IOR technology by chemical flooding. This technology has been applied to Shengli, Zhongyuan and Henan oilfields with remarkable benefits and social effects.
