缝洞型碳酸盐岩油藏单井注水替油生产特征研究

Research Production Character of Waterflood Stimulation for Single Well of Fractured-cavity Carbonate Reservoirs

碳酸盐岩缝洞型油藏在全球范围内分布广泛,且储量、产量巨大。塔河油田属于非均质性极强,地质情况复杂,储集空间多样。目前对此类油藏的研究在国内外尚处于探索阶段,急需进行相应的研究。本文利用了各种测试资料和油藏地质的研究成果,对塔河油田单元地层压力、含水率和产量的变化规律进行了分类系统研究,研究碳酸盐岩缝洞型油藏单井注水替油效果分析,为开展有针对性的开发措施提供理论依据,同时分析了各因素对注水替油效果的影响因素。

Fractured-cavity carbonate reservoirs exist widely in the world with massive reserve and production of petroleum stored in it.The reservoirs of Tahe are typically the fractured-cavity ones with high heterogeneity,complex geological condition and variable pore structure.The research in reservoir engineering for fractured-cave carbonate reservoirs is at the groping stage home and abroad.It is an urgent need to conduct the corresponding theoretical study.Based on the research of the production performance of T...
