摘要
目的提高乌5井区克拉玛依组油藏注水开发效果。方法在充分认识油藏静态地质特征的基础上,利用压力测试、油井产液剖面、注水井吸水剖面等测试结果,结合注水井和采油井生产数据的动态分析,认识各种地质及生产动态因素对注水效果的影响和控制作用。结果注入水在地质上主要受构造、沉积微相和储层物性3方面控制,工程上主要受注水时机、注水方式和注水强度的影响。结论有益的为开发同类油藏提供了该研究经验和借鉴。
Aim To improve waterflooding effectiveness of Kelamayi group oil field in Wu-5 well area. Methods Based on the sufficient study in static state of the resenroir, by use of the results of the pressure test, the production profiles, the injection profiles and the data of production, study kinds of geology and production factors which afected and controlled the movement of injection water. Results The injection water was mainly afected by structure, sedimentary microfacies and resenroir property in geology, and waterflood timing, water flooding regime, water intake per unit thickness in engineering. Conclusion These provided experience and reference for developing some kind reservoir.
