YB地区长兴组礁滩地震相精细刻画
|
摘要
为了准确划分YB地区长兴组的沉积相带,进一步开展长兴组礁滩储层精细预测,对YB地区长兴组进行了系统的地震相分析。主要采用人工神经网络地震相检测技术,对地震波形进行分类,区分了不同沉积体。首先对YB地区长兴组进行了系统的相模式分析;然后利用地震相切片技术,分析了YB地区长兴组各沉积时期相带发育及迁移情况;最后进行地震相平面分析,并对各种参数进行试验分析。较好地划分出了YB地区长兴组各沉积相带,认为YB地区长兴组主要划分为开阔台地相、礁后浅滩相、台地边缘礁滩相以及斜坡陆棚相四大相带,清楚地展现了生物礁滩的平面展布特征。
To accurately classify the sedimentary facies belts and carry out detailed reservoir prediction of reef-beach reservoir,the seismic facies of Changxing formation in YB area was systematically analyzed.Based on artificial neural network detection technology for the detection of seismic facies,the waveform was classified and sedimentary bodies were distinguished.Firstly,overall facies pattern was analyzed.Then,by using seismic facies slice technique,the development and migration of every sedimentary period in Changxing formation were studied.Finally,the areal distribution of seismic facies was analyzed and various parameters were tested.After the above steps,four sedimentary facies belts of Changxing formation were classified,including open platform facies,back reef beach facies,platform edge reef-beach facies,carbonate slope-shelf facies,which clearly displayed the areal distribution of reef-beach faices.
