摘要

 黄骅坳陷滨海斜坡区由于受到多物源影响,存在沉积亚相类型多、储层横向变化快、砂体预测困难等特点。通过对该区开展地震地质精细预测研究,明确了古物源、水下低隆起和沉积相带对海域地区砂体发育程度的影响。以沉积古背景为研究基础,依据地震响应特征并结合地震多属性分析,建立了研究区沉积地质模型,预测了砂体的发育模式。钻探结果表明,预测与实际吻合较好,证实该模式对预测研究区岩性油气藏分布具有一定指导意义。

Abstract

Concerned about the multi-sourced input, the littoral slope zone of Huanghua depression is characterized as types of depositional subfacies, fast change of reservoir physical property in lateral, and hard forecast of sand body. According to fine contrast of seismic and geology, the sand body formation in the maritime space is constrained by source input, low uplift underwater, and depositional facies. Based on sedimentary paleo\|background, seismic response features and seismic multi-attributes, we set up the geologic model and forecasted the distributed pattern of sand body. The drilled holes demonstrate that the forecast result is consistent with the real geology, suggesting this model would be significant to forecast the distribution of lithologic hydrocarbon reservoir.
