摘　　要：油房庄油田T9油藏经过长期注水开发,油井含水上升,油藏水驱不均,平面、剖面矛盾突出。本文主要从储层非均质性入手,结合动静态资料,分析其注水见效情况及水驱规律,研究认为T9油藏非均质性较强,水驱受效明显;油井见水主要受边水侵入、注入水突进、底水锥进等因素的影响;注入水沿高渗条带形成优势渗流通道,导致局部水驱不均;为封堵高渗层段、均衡油藏水驱实行堵水调剖、优化注水等开发技术政策,指导油田高效开发调整。T9 reservoir in Youfangzhuang oilfield has been developed by long-term water injection,with water cut rising,uneven water drive and prominent contradiction between plane and profile.In this paper,starting from the reservoir heterogeneity,combined with the dynamic and static data,the water injection effect and water drive law are analyzed.It is considered that the heterogeneity of T9 reservoir is strong,and the water drive effect is obvious;the water breakthrough of oil well is mainly affected by edge water invasion,injection water inrush,bottom water coning and other factors;the injection water forms a dominant seepage channel along the high permeability belt,which leads to the local uneven water drive.In order to guide the adjustment of high-efficiency development of oilfield,water plugging profile control and optimized water injection are implemented in high-permeability interval and balanced reservoir.
