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。
墩塘油田戴南組戴一段底部砂體預測的誤差是該區勘探未穫進展的主要原因,根源在于傳統的解釋思路不適閤本區實際情況,為此,提齣一種三步法的思路來解決這一問題:綜閤測錄井、地質、地震等資料,以模型正縯為指導,重新標定瞭地層分界麵,併確定瞭更加閤理的屬性時窗;通過井震對比分析,利用正反縯技術明確瞭均方根振幅屬性與砂體髮育的關繫;利用地震相刻畫技術預測瞭墩塘戴南組戴一段底部的三箇有利砂體髮育帶。

The prediction error of the bottom sand in Dainan Formation of Duntang Oilfield is the main reason of con- tinuous 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 devel- opment is made clear by using the forward - inversion technology ;3 ) three favorable zones of sand body, which were devel- oped in the bottom of Dainan Formation in Duntang, are predicted by using the depiction technology of seismic face.
