| 摘 要： | 塔河油田碳酸盐岩井周缝洞型储集体靶向酸压改造工艺针对性强，对于靶向目标精准定位与表征要求很高。围绕井周酸压增储提效，精准定量表征井筒附近储集体主应力方位、距离、规模、空间分布成为亟待解决的关键问题。从井孔与井周储层识别角度切入，采用一维资料-三维资料，多方法结合定量识别与刻画不同储层类型，在分类表征基础上，实现了模型的分类整合，构建了单元级次的多类型缝洞融合储层模型。然后，在单元级次模型基础上，创建了井周不同范围的可视化三维定量模型构建技术方法，建立了实际单井定量模型，并基于酸压靶向目标体三级八因素分类划分指标体系，确定了7种类型靶向目标体及适应的酸压技术方法。靶向酸压工艺矿场应用显示:靶向酸压井措施效果显著，同样区块范围井，比常规酸压方法平均增产倍比大，显著提高了酸压工艺的针对性和靶向性，有较好的推广应用前景。

| Abstract: | targeted acid-fracturing technology is very demanding of the Localization and characterization of the reservoirs near wellbores.It is the key to accurately and quantitatively characterize the location, distance, scale and spatial distribution of the main stress of the reservoir near the wellbore.We realized the integration of the different types reservoir and builded multiple types fusion model of fracture-vug reservoir using five kinds of methods to depict different reservoir type with one-dimensional data to 3d data.Based on the unit level model, a visualized 3d quantitative model method for different ranges of Wells is established, and a three-level single well quantitative model is established.Based on the nine-factor of four-level classification index system of acidizing fracturing, 11 types of target reservoir and its adaptation technology methods were determined.Targeted acid-fracturing oil field application results: the effect is remarkable with higher production, more than 3.6 times than a conventional acid-fracturing in the same oil block.It significantly improves the pertinence and targeting of acid-fracturing technology. |
