琼东南盆地东部构造坡折样式与层序地层发育特征
|
摘要
结合地震、测井和钻井等详细分析资料,利用工作站和地震解释软件,以琼东南盆地东部新生界地层为对象,开展了构造和层序地层的分析和研究。研究结果表明,在琼东南盆地东部发育有三种构造坡折带样式:断坡带,单一坡折带以及复合坡折带,并识别出由不同层序格架控制的多种低位域的沉积地质体,包括下切谷,盆底扇,斜坡扇和低位楔,其物源主要来源于研究区北部的陆架区;琼东南东部的低位体系域的特征和分布与三种层序格架样式相互对应,这些低位域砂体可成为有利的储层。结合前人的坡折带理论,揭示构造坡折带与该区内有效储集体分布的关系,预测潜在的勘探目标。
Based on the detailed seismic and well log data,utilizing work station and seismic interpretion software,taking Cenozoic strata in the east of Southeastern Hainan basin for an example,this paper studies the tectonic framework and sequence stratigraphy.Three types of tectonic slope-break zones were developed in the study area:the fault break-zone,the single slope-break zone and the combined slope-break zone.Considerable amount of geological bodies in lowstand system tracts(LST) controlled by different tectonic framework were distinguished,including incised channel,basin floor fans,slope fans,lowstand wedge,which implies that their soure rocks were mainly derived from the east of the continental shelf in the basin.The characteristics and distribution of LST in the area correspond to the patterns of sequence stratigraphy framework,and sandbodies in LST could be available reservoirs.Directed by the theory of slope-break zones,this paper indicates the relationship between tectonic slope-break zones and reservoir distribution,and predicts the potential prospecting targets.
