黄骅坳陷孔南地区孔店组一段物源区分析
摘要
黄骅坳陷孔南地区孔一段砂岩储集物性好,是研究区内重要的含油气层段。根据砂岩成分、重矿物特征、砂体分布体系和地震剖面等资料,对孔店南部孔一段物源方向及物源区母岩性质进行了系统研究。结果表明,孔南地区孔一段物源主要来自于盆地北部、东部、西部和南部,其中北部物源影响范围大,可进一步分出北西和北东两个方向。古物源与成因砂体的空间展布配置关系良好。砂岩组分的Dickinson三角图解显示,物源区构造背景为大陆块区、火山弧区和构造混合区。这些结果反映了黄骅坳陷孔店期盆地在中、新生代构造转型过程中陆内裂陷盆地内形成的具有多物源供给、三分性明显的沉积特点。
In the southern Kongdian region of Huanghua Depression,the first member of Kongdian Formation,with fine accumulation properties,is the important exploration intervals in the research area.The authors did a systematic research on the provenance and the characteristics of the parent rock by many methods such as the clastic composition analysis,heavy minerals analysis,seismic profile analysis etc.The results indicate that those are mainly controlled by four great sediment source regions,which are from north,east,south and west in the southern Kongdian region.The north provenance is the most important one and can be subdivided into two sub-sources,which are northwest and northeast.Provenance has favorable spatial combination with depositional system.By Dickinson triangular plot of clastic component,most of sands fall in the continental block and volcanic arc,and some in mixed provenance.These results reflect the Huanghua Depression basin is a developed intra-continental rift basin in the Cenozoic,and is featured by the sedimentary characteristics of one-third of obvious and multi-and-near sources in the Mesozoic and Cenozoic tectonic transition process.
