摘　　要：在通过油藏精细描述弄清构造和剩余油的分布的基础上,应用井网综合调整技术,实现了中原油田文51块多层砂岩特高含水期油藏开发对象的转移。通过井网综合调整,提高了二、三类储层的水驱动用程度,水驱动用程度提高12个百分点,综合含水下降了5.23个百分点,年产油增加1.6×104t,提高采收率3.1个百分点,开发效果得到了明显改善,对同类油藏开发井网调整具有一定的指导意义。On the basis of understanding the structure and remaining oil distribution through precision reservoir description, the well pattern integral adjusting technique is used to realize the transfer of development object of high watercut reservoirs in multi-layer sandstone of Block Wen 51 in Zhongyuan Oilfield. Through integral well pattern adjustment, the producing level of waterflooding is raised in the reservoirs of category I and II, with 12% of waterflooding producing level increase, 5. 23% of integral water cut decrease , 1. 6× 104 ton annual oil production increase and with obvious improvement of development effect, by which a guidance is provided for well pattern adjustment of similar reservoirs.
