摘要
由于二类油层沉积环境变化大,平面和纵向上具有严重的非均质性,使开发指标的影响因素变得更加复杂。本文主要分析了影响二类油层聚合物驱开发指标的六个因素:①聚驱控制程度、②渗透率、③渗透率变异系数、④注聚初含水、⑤注采井距、⑥有效厚度。从而能够更准确得把握开发指标变化规律,为制定合理的增产措施和建立一套适合二类油层开发特点的指标预测方法奠定坚实的基础。
Because of the diverse sedimentary environments and the severe heterogeneity on the horizontal and vertical directions in the thin and poor layers,the affecting factors of development index of polymer flooding have become more and more complex.In this paper,the author analyzed six factors which affect the development index of polymer flooding in the thin and poor layers:①control degree of polymer flooding、② permeability、③permeability variation coefficient、④initial water cut of polymer flooding、⑤injector producer distance、⑥net pay thickness.So we can accurately grasp the variation rule of development index,which lays a firm foundation for selecting reasonable stimulation measures,and establishing index prediction measures suitable for the developing characteristics of the thin and poor layers.
