摘要
高尚堡深层属于多层系复杂断块油藏,埋藏深、断块小、井段长、含油层系多、储层非均质性强、油水关系复杂,有效储层识别和小层对比难度大。开采过程中多数油水井都是多层合注合采,未考虑储层非均质性对开采效果的影响,致使油田产油量出现快速递减和含水快速升高等一系列问题。根据现场生产中表现出的问题,针对扇三角洲沉积特征和储层性质,通过油藏数值模拟研究,明确了油水井之间储层非均质性强弱对开采效果的影响程度,并有针对性地提出了相应精细调控技术对策,进而有效指导油田生产,达到油田高效开发的目的。
It has deep buried target, small block, long well, more oil-bearing series and strong reservoir hetero- geneity for the deep complex fault blocks in Gaoshangpu. It is very difficult to recognize effective reservoir and con- trast small layer. In the oil well production process, most oil wells and injection wells were commingling produc- tion. Because of ignoring horizon correspondence and the relationship between reservoir types and injection-produc- tion fine regulation, there have been a lot of problems include water cut rising and oil production decline in oil field production process. Considering single sand body lap mode, reservoir heterogeneity and injection-production con- nected condition, the reservoir physical property differences on the influence of the development of technical coun- termeasures is determined. The oilfield production can be effectively guided and achieved the purpose of efficient oilfield development.
