摘要:
中国南海北部湾盆地是具有巨厚优质烃源岩的新生代复杂断块油气藏。井旁构造、断层和断裂评价是勘探开发面临的重要难题。偶极反射横波远探测技术利用阵列声波测井仪向井外发射横波,接收井周地层中裂缝、断层等波阻抗界面反射回井中的横波并进行成像。使用低频偶极指向性声源,可以更精细地描述井外更远处裂缝、断层的方位与走向。该技术应用于南海北部湾盆地勘探开发中,能够对井旁断层位置和方位进行精细成像与刻画,用于帮助分析复杂断块区的井旁断层及构造,应用效果好。
Abstract:
The Beibuwan Basin in the South China Sea has been proved to have Cenozoic complex fault block reservoirs with huge thickness and high-quality source rocks. However, it is difficult to evaluate near-well structures, faults and fractures in exploration and development. The dipole shear wave remote detecting technology uses an array acoustic logging tool to emit shear wave outside a well, then receives the shear wave from the impedance interface of fractures and faults, and finally images the structures around the well. Using a low-frequency directional dipole acoustic source, the azimuth and strike of fractures and faults beyond wellbore can be described more precisely. Applied in the exploration and development of the Beibuwan Basin, the technology can finely image and characterize the location and azimuth of faults, and help to analyze faults and other structures near wellbores in complex fault blocks.
