| 中文摘要: |
| 胜利测井公司成功研制出一种新型的胜利多分量横波远探测成像测井仪(VMSI)，该仪器采用低频偶极声源设计，低频高效隔声体、高保真大数据快速传输技术，实现高信噪比多分量反射横波信号的采集，从而可以对井外远距离、不同走向的地质异常体进行探测；并结合专用成像处理软件，可以较好压制低频斯通利波反射，有效提取弱的反射横波信号，最终实现了远程偶极反射横波成像。该测井仪器理论上可以对井外320m范围内地质异常体进行探测，在刻度井的测试中清晰探测到80m内的地质异常体，实际测井中已成功获得井外100m范围内的成像结果。 |

| Shengli well logging company has developed a new instrument called Victory Multicomponent Reflected Shear wave Imager(VMSI). For VMSI, a low-frequency dipole source, a sound isolator design especially for low frequency and a fast high fidelity transmission technology for big data ensure the gathering of information with high signal to noise ratio and the imaging of geologic abnormal body far away from the borehole with different strike. Besides, a special processing software is developed to solve the problem of strong stoneley wave reflection and weak effective reflected shear wave signal for remote geological abnormity body imaging. With VMSI, the geological anomalous bodies in the range of 320 m outside the borehole can be imaged theoretically, while the distance reaches up to 80m when testing in the calibration well and the imaging results in the scope of 100m outside the borehole is got in the field well logging. |
