| 三维声波测井技术是近年来测井领域的重要进展,由于其集成了井孔轴向、径向和周向的三维信息探测能力,因而在各种复杂油气藏勘探开发中具有广阔的应用前景。从井孔声波探测的基本原理入手,对三维声波测井在井孔径向和周向的探测特性进行了研究。并且在传统资料处理方法的基础上,研发了适合三维声波测井的各向异性快速反演技术、径向速度层析反演技术以及井周慢度成像技术。现场实测的资料处理表明,三维声波测井仪器较传统多极子阵列声波测井仪器有较大优势,在探测井周地层三维信息方面有较好的应用前景。此外,该仪器也具有三维远探测的应用潜力。 |
| 英文摘要: |
| Three-dimensional acoustic logging technology has been an important development in the field of well logging in recent years. Because of its integration of three-dimensional information detection capabilities of borehole axial, radial and circumferential directions, it has broad application prospects in the exploration and development of various complex reservoirs. Starting from the basic principles of borehole acoustic detection, the radial and circumferential detecting characteristics of three-dimensional acoustic logging have been studied. Based on the traditional data processing method, anisotropy fast inversion, radial velocity tomography and borehole azimuthal slowness imaging technology which suitable for three-dimensional acoustic logging have been developed. Field data processing shows that the three-dimensional acoustic logging tool has great advantages than the traditional multipole array acoustic logging tool, and has a good application prospect in detecting the three-dimensional information of the formation around the well. In addition, the instrument also has the application potential in three-dimensional remote detection. |
