摘要
针对北二西二类油层聚驱方案编制过程中遇到的二类油层聚驱与三次加密水驱注采关系优化问题,通过明确分单元驱替方式,进行水聚区域的划分,研究得出相带接触方式和两驱注采关系优化的8种模式、6种调整方法,总结出优化两驱注采关系的射孔原则,使断层发育的北二西二类油层聚驱控制程度达到了81．7％,为提高二类油层聚驱效果提供了保证。
According to the injection-production relation between polymer flooding and tertiary infill drilling for classⅡreservoir during the formulation of polymer flooding program of Block Beierxi, 8 models and 6 adjustment methods about phase belt contact modes and injection-production relation coordination are concluded as well as the perforation principle , through the identification of recovery method and the division of different flooding regions. Therefore, control degree of polymer flooding of ClassⅡreservoir in Block Beierxi where faults developed reaches 81.7%, providing support for increasing the development effect of polymer flooding in ClassⅡreservoir.
