| 摘 要： | 油田水下窄小分流砂体进入中高含水期后,由于现井网对油层的水驱控制程度低,制约了分层注水调整技术优势的发挥,影响了开发效果。提出一套适合窄小砂体油田注采系统的调整,即以单砂体研究为基础,“分砂体、分阶段”采用层次分析法和模糊综合评价方法的“全方位优化转注方案 ”,对原井网进行了加密调整、细分注水。合理的注采系统调整是控制油田产量递减、提高水驱油采收率的有利措施。

| Abstract: | Layering injection water were restricted by the pattern arrangement of water drip control degree lower and have influenced on the development result with underwater narrow and small sandstone bodies have been middle-high water-bearing time. This paper put forward a series of regulated methods to be suited to narrow and small sandstone bodies oil field. It was called "the optimal steering injection scheme of all points". Based on a sandstone body, application methods of the gradational analysis and fuzzy synthetic evaluation gone on infilling well and fine injection. The rational regulated injection-production system are a favorable measure of control output decreasing and raise water drip recovery ratio. |
