| 摘 要： | 为了提高盆地定量分析的精度,必须在模拟过程中尽量采用动态参数,但如何准确获取各种动态参数是当前盆地分析模拟研究中的难点之一.在对“动态参数”的概念及其3种获取方法进行详细论述的基础上,提出了能更加准确地校正时间因素对各种模拟参数影响的“时间校正系数”概念,并以孔隙度为例,对其确定方法作了详细的阐述.“动态参数”和“时间校正系数”概念的提出和确定对盆地定量分析,特别是含油气盆地内各种演化史的深入研究会起到一定的作用.

| Abstract: | In order to improve the accuracy of quantitative research of basins,dynamic parameters must be used. But how to get all kinds of dynamic parameters exactly is one of the weak points of basin modelling at present. Based on a further discussion on the concept of dynamic parameters and three kinds of methods to obtain them,the author presents an important concept with theoritical and actual value,correction coefficient of time,which can correct the effect of time on those parameters, and has discussed its determination,taking porosity for instance. These two concepts may be useful to the study of basin numerical analysis,especially to the further study of many kinds of geological evolution. |
