摘　　要：地质勘探初期，在尚未取得原始地层压力实测资料之前，可以通过绘制地层压实趋势线辅助预测孔隙压力。其中建立工区地层的正常压实趋势线（方程）的关键是选取能反映地层压力实际情况的测井数据。川西地区须家河地层埋藏较深，对于该区深井砂泥岩地层压力的预测可采用等效深度法和Eaton法。利用等效深度法与Eaton法分别预测该工区的地层孔隙压力，结果表明，在该区运用等效深度法要优于Eaton法。In the early stage of geological prospecting, pore pressure can be predicted through drawing a formation compaction trend line before getting the original formation pressure data.The key to establish the normal compaction trend line (equation ) of the work area is to choose the logging data which can reflect the practical situation of formation pressure.Xujiahe strata in west Sichuan are buried deep. Equifinal depth method and Eaton method can be used to predict sand-slime rock formation pressure in deep wells of this area.The result shows that equifinal depth method is better than Eaton method in prediction of the formation pore pressure.
