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。

Abstract: The Ordovician reservoir in Tahe oilfield is characterized by extremely strong heterogeneity with enormous thickness of solution fissure-cavity reservoir rocks, during its development, most wells appear quick water breakthrough, quickly raising water-cut and quick production decline. This paper studied the geologic factors, recovery mechanisms and water coning of Ordovician reservoir in District No.3 by means of numerical simulation technique, put forward the principle of small oil well perforated extent,contolling recovery rate during production and early water or gas injection for supplementary energy. These provide foundation for reference for promoting high effective development of Ordovician reservoir in District No.3, Tahe oilfield.

Key words: Carbonate reservoir, solution fracture, vug, reservoir, numerical simulation, development mechanism, Tarim basin, Tahe oilfield
