          摘要:
          在等效深度法和Eaton法適用條件及壓力預測各環節誤差分析的基礎上,探討了預測參數的優選方法以及預測方法選擇的依據。超壓成因機制是壓力預測方法優選的最主要依據,等效深度法主要適用于欠壓實成因超壓預測,Eaton法適用于多種成因超壓的預測。對于超壓凹陷,通過分構造帶優選正常壓實趨勢線、三段式擬合上覆巖層密度—深度關系曲線以及迭代法確定伊頓指數c值,可以最大限度地減小預測壓力的誤差。以渤南洼陷地層孔隙壓力預測為例,在以生烴超壓為主的構造帶,采用Eaton法預測誤差較低,而在以欠壓實超壓為主的構造帶,等效深度法預測效果較好。
          Abstract:
          Abstract: Based on the analysis of the applicable condition sand the error of each pressure prediction link of the equivalent depth method and the Eaton method, the optimal methods of prediction parameters and the basis for the selection of prediction methods are discussed. The overpressure mechanism is the most important basis for the selection of pressure prediction method. The equivalent depth method is mainly applied to over pressure prediction caused by under-compact. The Eaton method is applicable to the overpressure prediction by multiple causes. For the overpressure depression, the error of the predicted pressure can be minimized by selecting the normal compaction trend line according to the tectonic zone, three-stage fitting overburden rock density-depth relationship curve and using iterative method to determine the Eaton index c. Taking the prediction of formation pore pressure in the Bonan depression as case study, in the tectonic zone dominated by hydrocarbon generation overpressure, the prediction error is lower by the Eaton method, while the prediction performance of the equivalent depth method is better in the tectonic zone dominated by under-compacting overpressure.
