Quantitative Water Injection Technology for Cavernous Fractured Karst Carbonate Reservoirs in the Tahe Oilfield

  • 摘要: 塔河油田碳酸盐岩缝洞型油藏进入注水开发阶段中期后,面临着注水效率低、有效期短等一系列问题。为解决这些问题,研究应用了以物质平衡方程为理论基础的量化注水开发技术。从注水时机量化、单井注水参数量化和单元注水参数量化等方面,分析、阐述了量化注水开发技术的理论依据、技术方法和应用效果。研究发现,量化注水技术可很好地将注水开发从定性判断转为定量分析,解决前期开发过程中定性注水带来的问题。该技术已应用142井次,累计增油10.95×104 t,注水有效率高达84.3%。研究表明,量化注水开发技术在塔河油田碳酸盐岩缝洞型油藏开发中效果良好,具有很好的推广应用价值。

     

    Abstract: In order to resolve a series of problems such as low water injection efficiency and short longevity that faced in the development period of water injection for cavernous fractured karst carbonate reservoirs in Tahe Oilfield, a quantitative water injection technology was studied and applied on the basis of material balance equations. The theoretical basis, technical method and application effect of quantitative water injection development technology have been analyzed and expounded in three aspects, including the quantification of water injection timing, water injection parameters in single well and unit water injection parameters. The quantitative water injection technology can avoid the problems caused by qualitative water injection in the early development process, and it has been applied in 142 wells, with a cumulative oil increment of 10.95×104 t, and the water injection efficiency higher than 84.3%. The results showed that the quantitative water injection technology had a great effect in the development of cavernous fractured karst carbonate reservoirs in the Tahe Oilfield, with good value of promotion and application as a best practice for similar reservoirs.
