摘　　要：介绍了灰色关联方法的原理及其在CB油田Chen2断块水驱开发方案中的应用。随着开发的不断深入,Chen2断块主力层系出现含水上升较快、单层突进现象严重、稳产难度变大等问题,应用灰色关联方法分析各个小层上注水井和各个生产井的关联度,发现西侧断层和构造高部位的井注水受效程度低,在该区域采取加密新井措施后显著改善了流动能力,从而增加水驱波及体积,有效控制含水上升,缓解层内和层间的矛盾,提高了采收率。The principle of grey correlation method and its application on the development plan of water flooding of Chen 2 Fault Block in CB Oilfield are introduced.As the progressive development went on,rapid increase of water cut and breakthrough along monolayer made the conditions of stable production worse in the main reservoirs.The grey correlation method was used to analyze the correlation degree between the water injection wells and production wells on every single layers,It was found out that water flooding effects were lower in the western fault and high area of the structure.By infill well pattern,the flow capacity in the area was improved,the waterdrived sweep volume was increased,increase of water cut was controlled effectively,the inconsistency between innerbeds and interbeds was solved,and the recovery ratio was increased.
