摘　　要：塔河油田奥陶系油藏的储集层为溶蚀缝-溶洞型巨厚碳酸盐岩储集层,非均质性极强。在开发过程中,大部分油井表现出见水快、含水上升率快、产量递减快的特点,给油藏开发带来了很大难度。应用数值模拟技术对塔河油田3区奥陶系油藏的地质因素、开采机理、水锥等进行研究,提出了油井打开程度应小、控制采油速度、早期注水(气)补充能量等建议,为实现塔河油田3区奥陶系油藏高效、合理开发提供了参考依据。The Ordovician reservoir in Tahe oil field is characterized by extremely strong heterogeneity with enor-mous thickness of solution fissure-cavity reservoir rocks,during its development ,most wells appear quick water break-through,quickly raising water-cut and quick production decline.This paper studied the geologic factors,re covery mech-anisms and water coning of Ordovician reservoir in District No.3by means of numerical simulation technique,put for-ward the principle of small oil well perforated extent,controlling recovery rate during production and early water or gas injection for supplementary energy.These provide foundation for reference for promoting high effective develop ment of Ordovician reservoir in District No.3,Tahe oilfield.
