摘　　要：裂缝是油气的重要储存空间,电缆测井在直井中研究致密砂岩、碳酸盐岩等裂缝性储层较多。然而,关于水平井裂缝储层双感应测井响应研究较少,影响了水平井在裂缝储层的评价。由于水平井与直井工程环境不同,测井响应结果存在差异。为此,利用有限元方法建立水平井裂缝储层模型,对裂缝储层中的水平井双感应测井进行数值模拟分析。通过分析裂缝电导率与裂缝宽度、裂缝长度和裂缝弯曲度同时作用时的双感应测井响应特征,总结出不同因素对水平井双感应测井响应影响的规律。数值模拟结果可为水平井裂缝储层识别与评价提供技术支撑。Fractures play a critical role in storing oil and gas,and cable logging has been extensively used to study fractured reservoirs such as tight sandstone and carbonate rocks in vertical wells.However,there is limited research on the dual induction logging responses of horizontal wells in fractured reservoirs,which affects the evaluation of horizontal wells in fractured reservoirs.Due to the different engineering environments between horizontal and vertical wells,there are variations in logging response results.In this study,a finite element method is utilized to establish a model of horizontal wells in fractured reservoirs and numerical simulation analysis is conducted on dual induction logging of horizontal well in fractured reservoirs.By analyzing the characteristics of dual induction logging responses when fracture conductivity interacts simultaneously with fracture width,length,and degree of curvature,the study summarized the influence patterns of different factors on the responses of dual induction logging in horizontal wells.The numerical simulation results can provide technical support for the identification and evaluation of fractured reservoirs for horizontal wells.
