摘　　要：水力压裂是高效开发低渗储层的关键技术手段,监测地下压裂裂缝参数对于评价压裂改造效果、优化后续设计具有重要意义。然而由于海上作业环境的特殊性及成本限制,常规裂缝监测技术在海上应用效果不佳。通过前期开展的大量阵列声波测井测试资料,基于阵列声波测井技术建立了一套评价压裂裂缝参数的方法,利用横波波幅、声波各向异性以及径向速度剖面监测裂缝高度,利用声波远探测技术监测裂缝延伸距离,并进行了现场综合应用。结果表明:应用该方法能较为精准地监测缝高,同时能定性评价裂缝延伸距离,为渤海油田低渗储层压裂效果评价提供了一套有效的思路和方法。Hydraulic fracturing is a key technical means for the efficient development of low permeability reservoirs.Monitoring the fracture parameters of underground fracturing is of great significance for evaluating the fracturing effect and optimizing the subsequent design.However,due to the particularity of offshore working environment and cost limitation,the conventional fracture monitoring technology is not effective in offshore application.Based on a large number of array acoustic wave logging test data carried out in the early stage,a set of methods for evaluating fracture parameters was established by means of array acoustic wave logging technology.Shear wave amplitude,acoustic anisotropy and radial velocity profile were used to monitor fracture height,and acoustic wave remote detection technology was used to monitor fracture extension distance,which was comprehensively applied in the field.The results show that apllication of this method can accurately monitor the fracture height and qualitatively evaluate the fracture extension distance,which provides a set of effective ideas and methods for evaluating the fracturing effect of low permeability reservoir in Bohai oilfield.
