摘要

玛湖凹陷在侏罗纪时期整体处于浅水沉积环境,湖盆宽缓、基底振荡,在凹陷西侧斜坡区沉积多套砂泥岩薄互层,易于形成岩性油气藏;该时期还沉积多套煤层,煤层的发育对下部地层的地震响应产生屏蔽作用,造成砂泥层的波阻抗无明显差异,无法进行常规的储层反演预测。通过测井曲线对岩性变化敏感性分析,采用密度和中子曲线共同构建拟声波曲线,使得该曲线削弱煤层影响,能够清晰地反映地层岩性的差异;并以此为约束条件进行拟声波地震反演,解决了该区薄储层预测的难题,取得较好的应用效果。

Abstract：

There are multiple combinations of sandstone and mudstone interbeds and also plenty of coal seams in the middle-shallow strata of Mahu sag's slope zone, due to the slow slope background and shallow lake environment of water oscillation since Jurassic. In addition, the lithologic reservoir can be found in the zone, but the shielding effect of coal seam makes it impossible to predict the reservoir, due to the unclear response of the thin interbed from seismic and acoustic logs. Therefore, the wave impedance inversion cannot distinguish sandstone from mudstone clearly. In view of such a situation, the technique of Pseudo-acoustic curve reconstruction was used in this study. By analyzing multiple well logs, the density and neutron curves, which can weaken the influence of coal seam and reflect the characteristics of sandstone and mudstone interbeds, were selected to rebuild pseudo-acoustic curves and then perform inversion with the rebuilt curves, thus improving greatly the accuracy of reservoir prediction.

Key words： Mahu sag's slope zone coal seam thin-interbed sandstone pseudo-acoustic inversion reservoir prediction
