Quantitative water injection of fractured-cavity oil reservoir in carbonate rocks in Tahe oilfield

  • 摘要: 利用蚂蚁体追踪技术和井间干扰试验,实现缝洞关联关系的精细描述和连通性的定量化表征,逐步建立了缝洞型油藏定量化注采井网构建技术,极大的提高了注水有效率。根据不同岩溶背景区储层发育特征,构建了风化壳区多维井网、暗河区立体结构井网和断溶体背景线状井网,形成了差异化井网构建技术。在矢量化井网构建的基础上,利用弹性驱+水压复合驱水侵计算模型,初步实现底水油藏注水强度定量化;利用注采对应曲线,初步实现了封闭弹性驱油藏注水强度定量化;通过分析示踪剂响应特征曲线,实现了注水周期定量化;通过综合分析能量变化曲线和物质平衡方法,实现各向分水率定量化计算。实例应用表明,上述技术可有效提高水驱采收率。

     

    Abstract: By using the ant tracking technique and inter well interference test,the quantitative characterization of fine description and connectivity of cave and fracture to realize the relation between cave and fractures was carried out,and the technology of quantitative injection-production pattern of the seam type reservoir was gradually established,which greatly improved the waterflooding efficiency.According to different backgrounds of karst reservoirs,a multi-dimensional injection-production well pattern in weathering crust area,a spatial structure well pattern in underground karst area and a linear well pattern in fault karst area were established,and the differential well pattern construction technology was formed.According to the well pattern construction technology,by using the models of elastic flooding and hydraulic complex flooding,the water injection intensity of bottom water reservoir has been quantified.Based on injection-production corresponding curve,quantitative determination of water injection strength of closed elastic flooding reservoir has been quantified.The water injection cycle is quantified by the response characteristic curve of the tracer.Quantitative calculation of water diversion rate in different directions was realized by means of the comprehensive energy change curve and material balance method.The application results indicate the technology can effectively enhance the recovery degree of waterflooding reservoirs.
