摘　　要：在阐述龙虎泡油田初期天然能量开采、转注后实施"三分、五清"精细油藏管理和提压注水效果的基础上,针对油田高含水期注水开发中存在的井网对砂体控制程度低、剩余油分布相对零散、注采系统不完善等问题,依据油藏数值模拟、油藏工程方法及高含水期开发调整矿场试验结果,研究形成了反九点转五点注采系统调整、以挖潜零散剩余油为主的局部井网加密调整、中渗透油层高含水期提液增产调整和多油层高含水期聚合物深度调剖技术。高含水期注水开发调整技术控制含水率、递减率和提高采收率效果显著,对类似油田的开发具有重要指导意义。On the bases of the following development measures in the Longhupao Oilfield： initial natural energy production, post-transfer “three-division and five clarification” fine reservoir management and enhancing water in- jection pressure, in the light of the problems existed in the development of the water flooding at the high-water-cut stage including lower controlled degree on the sandbodies by the well patterns, relatively scattered remained oil dis- tribution, imperfect injection-production system and so on, the following simulations are figured out by means of oil reservoir numerical simulation, reservoir engineering methods and the high-water-cut developing field test results： five-spot injection-production system adjustment transferred from the inverted nine-spot well pattern, partially in- filled adjustment taking the potential-tapping of the scattered remained oil as the main simulation, liquid and pro- duction increasing adjustment for the medium-permeability oil layers at the high-water-cut stage and moreover the deep profile-controlling technique by polymer in the multi-layers at the stage. The effects of the high-water-cut wa- terflooding adjustment techniques such as controlling the water cut and decline ratio and moreover enhancing the re-covery factor are remarkable and obvious, and furthermore all these achievements possess important guiding signifi- cance for the development of the similar oilfields.
