摘要:
偶極子聲波測井采用偶極子激發,在井筒中激發撓曲波沿井內流體傳播,偶極子波形具有明顯的頻散效應,低頻截止值處橫波速度為地層的橫波速度。有效的頻散校正方法是偶極子聲波測井有效應用的關鍵技術。對振幅相位估計法進行了研究,設計指定波數的濾波器建立目標函數,通過濾波器的權函數進行擬合函數的求取,得到偶極子波形的頻散曲線,可以獲得較高分辨率的頻散曲線。求得頻散曲線后,采用直方圖和擬合函數法進行了頻散校正方法的研究。通過對模擬數據的對比,得出擬合函數的頻散校正方法能獲得較高的頻散校正結果。實際數據處理驗證了該頻散校正方法的有效性。
Abstract:
Dipole acoustic logging uses dipole sources to shoot flexural wave which then propagates in the fluid in the borehole. The dipole waveform is obviously disperse. The velocity of the shear wave at low cut-off frequency is equal to that of the shear wave of formation. An effective dispersion correction method is important for the effective application of dipole acoustic logging. This paper studies the amplitude phase estimation algorithm and establishes the objective function by designing a filter with specific wave number. The dispersion curve with high resolution can be obtained by getting the fitting function from the weight function of the filter. Then histogram and fitting function methods are used to study dispersion correction. By comparing simulated data, it is concluded that the dispersion correction method based on the fitting function can provide dispersion correction results with higher precision. The validity of the dispersion correction method has been verified by actual data.
