摘要
由于缝洞型碳酸盐岩储集体的强烈非均质性,给开发井的部署及调整带来极大困难,因此,划分缝洞单元、弄清井间连通性成为提高开发井的命中率及合理调整的有效手段。针对缝洞型碳酸盐岩储层的复杂性,提出综合利用干扰试井法、流体性质分析法和油藏压力系统法等进行井间连通性研究,从而划分流动单元,指出了划分流动单元的研究意义。
Fractured-cavity carbonate reservoir is strongly heterogeneous, which brings about great difficulties for deploying and adjusting development wells. Therefore, the classification of fractured-cavity units and the unraveling of interwell connectivity are effective means for the success-rate enhancement and reasonable adjustment of well. Aimed at reservoir complexity, it is proposed that an analysis of interwell connectivity be conducted comprehensively by interference testing, fluid property analysis and reservoir pressure system. Thus, the flow units are classified for reservoir.
