琼东南盆地2号断层构造转换带及其对砂体分布的控制
|
摘要
断陷盆地内构造转换带的有效识别对确定物源方向和扇体的发育位置具有重要意义。本文基于典型地震资料追踪、解释、闭合和钻井岩芯资料分析,通过应用断层活动性定量分析、以及古地貌恢复等技术,揭示了琼东南盆地2号断裂陵水-松南段发育一接近式构造转换带。转换带位置在剖面上表现为一系列堑垒结构低凸起;断层定量分析位移-距离曲线上表现为断层活动性微弱;古地貌上表现为一个分隔陵水凹陷和松南凹陷的NW向脊状凸起等特征。构造-地层分析表明,该转换带对陵水组陆相碎屑砂体具有非常显著的控制作用,砂体是沿着转换脊部位向两侧运移的,其下部毗邻的始新统、崖城组是重要的烃源岩层,垂向发育的断裂又组成了良好的油气垂向运移的运输通道,因此是寻找有利油气藏的关键部位。
In rifted basin,tectonic transfer zones play very important roles in controlling both provenance and sedimentary system distribution.Based on integrated analysis of seismic data,core and logging,quantitative analysis of fault activity and reconstruction of palaeogeomorphology,we discussed the features of the transfer zone of the No.2 fault between Lingshui and Songnan section in the Qiongdongnan Basin(QDNB) and its controls on the deposition.The transfer zone consists of a series of grabens and horsts in the profiles;fault displacement-distance curve of the segments shows low values reflecting feeble fault activity;its palaeogeomorphology displays a high relief that separates Lingshui and Songnan sag.Transfer zone constrains the sediments transporting along its hinge and dispersing sidewards as shown by tectonic-stratigraphic analysis.Consequently the favorable sandbodies distribute on the both sides,adjacent to the source rocks of the Eocene and Yacheng formation of Oligocene in Lingshui and Songnan sag,besides,the faults provided the pathways for hydrocarbon migration.Therefore,such transfer zone is the key for locating suitable hydrocarbon reservoir.
