          摘要:
          針對塔里木盆地克深地區強烈構造封閉擠壓作用導致異常高壓在聲波時差測井曲線上無明顯異常增大特征的問題,討論ED法、ET法、FP法和BS法計算地層孔隙壓力的適用性,將這些方法優化編程,重點計算有實測壓力數據井段的地層孔隙壓力。通過計算分析和驗證,給出BS法中A、B、U等3個關鍵參數的取值范圍,認為基于有效應力卸載機理的BS法更適合于計算當聲波時差曲線變化不明顯時的異常高地層壓力。該法較好地解決了塔里木盆地克深地區利用聲波時差測井曲線準確計算異常高壓的難題。
          Abstract:
          Abstract: To address the problem that the abnormal high pressure in the Keshen area of the Tarim Basin caused by strong tectonic confinement extrusion has no obvious abnormal increase on the acoustic travel time logging curve, the applicability of the ED method, ET method, FP method and BS method are discussed. The methods are optimized and programed to calculate the formation pore pressures of the well sections with measured pressure data. Through calculation analysis and verification, the range of values of three key parameters A, B and U in BS method is determined. It is considered that the BS method based on the effective stress unloading mechanism is more suitable for calculating the abnormal pressure when the variation of the acoustic travel time curve is not obvious. The proposed method could better address the problem of accurate calculation of abnormal high pressure using acoustic travel time logging in the Keshen area of the Tarim Basin.
