摘　　要：为了保证盆地水动力模拟计算结果与实际间的吻合程度 ,提高模拟的可靠性 ,强调了模型中所涉及各参数的正确选取。通过对大量测试、测井、实验分析数据的综合、归纳 ,建立了水动力模拟中关键参数的求取方法。这些参数主要包括 :声波时差 -孔隙度转换关系、各小区代表性孔隙度 -深度关系、油气地下密度、孔隙度 -渗透率关系、热史恢复参数、地层剥蚀量等。最后 ,根据石西 1井的古水动力模拟结果 ,说明了古水动力恢复结果的可靠性 ,并就古水动力的发育历史进行了分析。Basin modeling is a key technology on studying hydrodynamics. Emphasis on the reliability of special simulation parameters has been paid to the selection of parameters involved in the models, in order to guarantee the agreement of modeled results and really geological pattern. A series methods in the acquiring key parameters on hydrodynamics has been set up, mainly through comprehensively generalization of large quantity of tests, well logging and analysis results of experiment. The parameters are as follows: conversion relationship between interval transit time and porosity, links of representative porosity and depth in different areas, relation of porosity with permeability, the relationship between R o and depth, parameters of thermal history, the stratigraphic erosion and so on. Finally, the reliability of modeling and restoring result of paleo hydrodynamics is illustrated, and the evolution history of paleo hydrodynamics is analyzed according to modeling results of paleo hydrodynamics of well Shixi 1 in the hinterland.
