摘　　要：渤南油田低渗透油藏注采井网二次不完善,削弱了油田稳产基础。通过注水井数及注采对应率变化规律研究,分析了造成水井停注的因素,指出水质不合格和套管损坏是注采井网二次不完善的主要原因,提出了水质精细处理、油层改造和油井转注等针对性的治理对策。实施后注入水水质明显改善,增加和恢复有效注水井点43个,开发效果显著好转。Foundation of stable production of low permeability reservoir,in Bonan Oilfield,is undermined by incompletion of injection-production pattern.It has been found,by studying the variation laws of number of injection wells and change of corresponding rate of injection-production,analyzing the factors affecting injection wells,that the two chief reasonss causing the incompletion are given.Such proposals,such as the fine treatment of water,modification of oil bed and transformation of production well,were proposed.After these measurements have been taken,the water quality has been obviously improved,43 efficient injection locations have been improved or restored and the production effects have become outstandingly well.
