- 冀东油田分层注水工艺的发展遵循引进、消化、吸收与改进、提高、配套的技术发展方针,形成了具有本油田特色的深、斜井细分注水工艺技术.文章介绍了二级三段、三级四段分层注水的工艺原理和技术特点以及在冀东油田的实际应用效果.通过细分注水,基本满足了冀东油田深、斜井在高温、高压复杂条件下的注水开发需求,尤其在主力区块柳13区块和高5区块取得了显著效果,减缓了油田含水上升速度,提高了水驱储量动用程度.
In this paper, the technologies of second-stage triple section and third stage quadruple section water injection were introduced,and their a-pplications were involved in Jidong Oilfield.By subdividable water injection,the need for water injection was met in Jidong Oilfield deep and deviated wells with high temperature and high pressure.The multistage water injection has been successfully used in Jidong Oilfield, especia-lly in its major blocks- Liu 13 and Gao 5, with the speed of water rise slowed down and the water drive reservoir increased.2005,S1(S1): 67-71 收稿日期：2005-3-7分类号：TE25作者简介：李建强(1969- ),男,河北邢台人,工程师,1991年毕业于重庆石油学校,1999年毕业于石油大学油藏工程专业,现任中国石油冀东油田公司采油工艺研究院井下工具室主任.
