【摘要】：古龙凹陷位于松辽盆地中央坳陷区西部,齐家——古龙凹陷的南段,是盆地的二级构造单元,是一个长期发育的继承性凹陷。本次研究的X工区即位于松辽盆地北部古龙凹陷。本文主要以古龙凹陷X工区三维资料做为地震数据基础,充分利用区内地震、地质、钻井等资料来进行课题研究,通过研究提高小断层、微幅度构造,对工区内的成藏要素进行分析。本次解释工作,对古龙凹陷三维地震资料进行了高精度构造解释,克服了工区数量多,地震资料缺乏统一性,构造解释精度不够,储层预测精度不够等诸多问题。一方面对主要构造层进行构造的精细解释,另一方面对中浅层油层组的岩性进行分层预测及单砂体的空间识别与刻画。本次岩性解释,通过去区域内生储盖等条件的综合分析,对古龙地区黑帝庙油层组的沉积规律及储层特征进行了研究,总结了研究区黑帝庙油层的成藏机制及成藏模式,并对研究区内的有利区进行了预测。完成了古龙地区T06、T05、T04、H22顶、H23顶5个反射层顶面高精度构造图(1:2.5万、线距2m);形成了提高微幅度构造和小断层解释能力的技术和流程,能够识别垂直断距≥3m、构造幅度≥4m的断层和构造;提交古龙地区黑帝庙油层构造样式分类图断裂生长指数剖面、断裂系统划分图、油源断层分布图;提交古龙地区黑帝庙油层砂体尖灭带分布图;对古龙地区黑帝庙油层油气富集区带进行了预测。
[Abstract]:Gulong sag is located in the west of the central depression of Songliao Basin and the southern section of Qijia-Gulong depression. It is a secondary tectonic unit of the basin and is a long-term inherited depression. The X-work area of this study is located in the Gulong Sag in the north of Songliao Basin. In this paper, the 3D data of X working area in Gulong sag are taken as the basis of seismic data, and the seismic, geological and drilling data in the area are fully utilized to carry out the research. Through the study of improving the small fault and micro-amplitude structure, The factors of reservoir formation in the working area are analyzed. In this paper, the high precision structural interpretation of 3D seismic data in Gulong sag is carried out, which overcomes many problems, such as large number of working areas, lack of uniformity of seismic data, insufficient precision of structural interpretation, insufficient accuracy of reservoir prediction, etc. On the one hand, the fine interpretation of the main structural layers is carried out; on the other hand, the lithology of the middle and shallow reservoirs is predicted by stratification and the spatial identification and characterization of the single sand body are carried out. In this lithology interpretation, the sedimentary law and reservoir characteristics of Heidimiao reservoir formation in Gulong area are studied through the comprehensive analysis of the conditions such as the generation, reservoir and caprock in the region, and the reservoir forming mechanism and the reservoir forming mode of the Heidimiao reservoir in the study area are summarized. The favorable areas in the study area are forecasted. The high precision structural map of the top of 5 reflectors of T06T05T04H22 and H23 in Gulong area has been completed, with a high accuracy map of 1: 25 000 and a line distance of 2 m, which has formed a technique and process to improve the interpretation ability of micro amplitude structures and small faults. The faults and structures with vertical fault spacing 鈮，
