摘要:

在地震勘探中,由于传播介质的吸收衰减,接收到的地震信号频率降低,严重影响了地震资料的品质,因此必须对其衰减进行补偿。 VSP 数据接收的是直达波,旅行时短,信噪比高,应用谱比法计算的 Q值比较可靠。 然而工区内的 VSP 数据毕竟有限,仅几口井的 Q 值代表不了整个区域。 基于常规 Q 值经验公式及拟合 Q 值计算方法,依托拾取的精确速度谱,通过 VSP 数据计算的 Q 值进行标定,进而建立区域内的拟合 Q 体。 通过实际应用及对比,该技术可使地震资料的能量和频率均有所提高,计算的 Q值可靠,是值得借鉴的一种新方法。

关键词: 拟合 Q 体, 吸收衰减, 分辨率, 振幅谱, 谱比法, 频谱

Abstract:

 Due to the absorption and attenuation in seismic exploration, the received frequency is reduced, which seriously affects the quality of the seismic data. Therefore, the data must be compensated for its decay. VSP data receives the direct wave, and the traveling time is short, so it has high S/N, and Q value calculated by spectral ratio method is more reliable. However, the number of VSP wells within the region is limited, so the calculated Q value can not represent the entire region. This paper presented a combined method to calculate the fitting Q value, which is based on the Li Qingzhong formula. It relies on the exact velocity spectrum picked. This Q value is calculated after VSP calibration data, and creates a variable stereoscopic Q model. By comparing the application of actual data, this fitting Q modeling technology can improve the overall energy and frequency. This calculated Q value is reliable, and this new method is worth of learning.

Key words:  fitting stereoscopic Q, attenuation, resolution, amplitude spectrum, spectral ratio method, frequency spectrum
