摘要
为研究伊拉克鲁迈拉油田阿尔比阶Nahr Umr组碎屑岩油藏油水界面倾斜成因,提高油气储量评估的准确性及开发方案部署和调整的合理性,在系统总结造成倾斜油水界面成因的基础上,综合利用测井资料、电缆地层压力测试资料以及区域地质资料,从地层水流量估算、油水界面倾斜幅度分析、油水压力梯度响应特征和区域压力变化规律4个方面进行了论证。认为水动力作用是造成阿尔比阶Nahr Umr组碎屑岩油藏油水界面倾斜的主要原因,水动力来源于东北部的特罗斯—扎格罗斯逆冲断裂褶皱带地表水的补充。
To understand the genesis of inclined water oil contact in Nahr Umr clastic reservoir of Albian stage in Rumaila oilfield and improve the accuracy of oil and gas reserves estimation and rationality of development plan and adjustment, four aspects are discussed including formation water discharge, inclination degree of water oil contact （WOC） , characteristics of oil and water pressure gradient response and regional pressure variation by analyzing the data of well logging, wireline formation pressure and regional geology, based on the summaries of the different causes of inclined WOC. It is considered that hydrodynamism is the main reason to result in the inclination of WOC in clastic reservoir of Albian Nahr Umr formation and the hydrodynamic force is sourced from the surface water supply in Teros-Zagros thrust-fault fold belt in the northeastern part of the oilfield .
