绥滨坳陷滨参1井地震地质层位标定及其地质意义
|
摘要
为有效解决地震解释中层位追踪的闭合,经岩芯、测井数据、速度资料、属性剖面、合成记录制作等分析,对滨参1井重新进行了地震地质层位的标定。与前人标定的结果比较,基底顶面T5反射时间由2 100 ms调整为1 843 ms;城子河组顶面T4-2的反射下调一个相位。依据本次标定结果新的解释方案,绥滨组+东荣组由原解释方案的全区分布改为局部分布,且向北有增厚趋势;对城子河组顶面埋深由1 692 m调整为2 246 m,城子河组厚度的计算也相应发生变化。
In order to solve efficiently the problem of tracking and closing horizons,the authors calibrated the seismic geological horizon in Bincan well 1 again by analyzing drilling core,logging data,velocity data,attributive profile,synthetic record,etc.Compared with the results calibrated previously,the reflection T_5 of the basement top is changed from 2 100 ms to 1 843 ms;reflection T_(4-2) of Chengzihe Formation top is declined for one seismic phase.According to the new calibration results,the distributions of Suibin Formation and Dongrong Formation are reconsidered as local in nature,but regional;and their thickness probably increased northward.The buried depth of the Chengzihe Formation top is changed in account from 1 692 m to 2 246 m,and correspondingly,the thickness of Chengzihe Formation is also changed in account.
