In compiling areal isopach of a basin from seismic horizon structure map, we can use the residual thickness at both sides of fault plane to show the horizontal distribution of a fault. Whether the equivalents at the both sides of the fault plane of a normal fault contact each other or not, the residual thickness values are lower in middle part and higher in both sides. The boundary fault and pinch-out should be located according to the major limit structure map. Besides, the structure maps compiled by different...

In compiling areal isopach of a basin from seismic horizon structure map, we can use the residual thickness at both sides of fault plane to show the horizontal distribution of a fault. Whether the equivalents at the both sides of the fault plane of a normal fault contact each other or not, the residual thickness values are lower in middle part and higher in both sides. The boundary fault and pinch-out should be located according to the major limit structure map. Besides, the structure maps compiled by different people or in different time should be checked and modified so as to guarantee their accuracy and completeness.

在利用地震层位构造图编制盆地区域性等厚图时,可以用断层面的残留厚度来描绘断层在平面上的分布。接触断面与不接触断面的残留厚度值为中间小两边大,边界断层与尖灭线要按照构造图上范围较大者来确定。此外,还要对不同时期做的或不同人做的构造图作适当的审查和修改,以保持资料的正确性与完整性。

Jiuxi basin is small, however, the seismic velocity varies drasticly in both horizontal and vertical directions because the physical and chemical characteristics of rocks vary severely and the formations are complicatedly fractured.Fortunately, both the horizontal and vertical variations in velocity are regular in this basin, thus the velocity curve of each seismic horizon can be obtained using known logging velocity curves or velocity curves from velocity spectra.

Jiuxi basin is small, however, the seismic velocity varies drasticly in both horizontal and vertical directions because the physical and chemical characteristics of rocks vary severely and the formations are complicatedly fractured.Fortunately, both the horizontal and vertical variations in velocity are regular in this basin, thus the velocity curve of each seismic horizon can be obtained using known logging velocity curves or velocity curves from velocity spectra. The corresponding horizon velocity curves are used to make time-depth conversion of T_5 and T_s seismic horizons. The error analysis of 36 Wells in this basin shows that relative errors between the converted depth and actual depth are less than 5% respectively (except few), fulfiling the accuracy requirement in this prospect. If the time-depth conversion is made using the general velocity in this area, the relative errors of T_s horizon are above 10%, which does not fulfiling the accuracy requirement. Obviously, mapping seismic data by horizon velocity curve is valid, because it can bring a good timedepth conversion of seismic data in this basin.

酒西盆地面积很小,地层分割性强,岩石介质的理化参数变化范围很大,使盆地内的地震波速度在横向和纵向上变化剧烈。但是,速度的变化在横向和纵向上具有规律性。根据速度变化的这一特点,我们利用测区内已知钻井的速度曲线或速度谱点的速度曲线,求出各个地震层位的分层变速曲线。然后用分层变速速度对地震反射层T_5和T_s作时-深转换成图,与测区内36口井进行投井深度误差分析,结果投井深度相对误差均在5%以内(个别井除外),符合本区成图精度要求。而采用本区的综合速度进行时-深转换成图,T_s层投井深度相对误差均在10%以上,超出了本区的成图精度要求。由此说明,在酒西盆地应用分层变速速度成图是正确的,较好地解决了该区地震资料进行时-深转换的速度问题。
