针对濮城油田沙二下油藏高含水开发后期存在开发对策不适应、层间矛盾突出的问题,开展复杂断块油藏精细描述和剩余油潜力再认识研究,在现有层系控制下,主力层恢复井网、有效提液,二三类层重组井网、精细注水,有效动用潜力层,改善多油层非均质油藏后期开发效果。 Aiming at the problem that there are some problems in the later stage of high water cut development of Pucheng Oilfield, such as the development countermeasure and the obvious contradiction between layers, the detailed description of the complex fault block reservoirs and the re-understanding of the remaining oil potential are carried out. Under the control of the existing strata, The main layer of recovery well pattern, effective mention liquid, two or three types of reorganized well pattern, fine water injection, the effective use of potential layers, improve multi-reservoir heterogeneity reservoir late development effect.
