摘要

墩塘油田戴南组戴一段底部砂体预测的误差是该区勘探未获进展的主要原因,根源在于传统的解释思路不适合本区实际情况,为此,提出一种三步法的思路来解决这一问题:综合测录井、地质、地震等资料,以模型正演为指导,重新标定了地层分界面,并确定了更加合理的属性时窗;通过井震对比分析,利用正反演技术明确了均方根振幅属性与砂体发育的关系;利用地震相刻画技术预测了墩塘戴南组戴一段底部的三个有利砂体发育带。
The prediction error of the bottom sand in Dainan Formation of Duntang Oilfield is the main reason of continuous exploration failure of the area,because the traditional interpretation ideal is unfit to the real circumstances.Aiming at the problem,a kind of three-step method is put forward:1) on basis of logging,geological,and seismic data etc.,and taking the forward model as a guide,the stratigraphic interface is recalibrated,and more reasonable attribution window is determinated;2) according to well-seismic comparative analysis,the relation between RMS attitude and sand body development is made clear by using the forward-inversion technology;3) three favorable zones of sand body,which were developed in the bottom of Dainan Formation in Duntang,are predicted by using the depiction technology of seismic face.
