摘要:

为了弄清楚珠江口盆地惠州凹陷新生界地层泥岩压实与油气生成和聚集的关系,首先探讨了该地区泥岩压实的特征,并运用最高热解温度和生烃指数等对欠压实的成因进行了讨论。研究表明:从纵向上来看,惠州凹陷内发育浅部快速压实段、正常压实段和低幅度欠压实段等3种类型,浅部快速压实段主要发育在深度小于700m的万山组和第四系地层,正常压实段自万山组底部或者粤海组顶部到珠海组底部或者恩平组顶部(1800～3200m),低幅度欠压实段自恩平组顶部向深部延伸到文昌组(2400～4000m);从横向上来看,惠州凹陷划分为东北部和中西部两个具有不同欠压实特征的区域,东北部欠压实区地层发育珠江组—韩江组和文昌组—恩平组2个低幅度欠压实段,中西部欠压实区只发育文昌组—恩平组欠压实段;珠江组—韩江组欠压实段主要由泥质高含量和快速沉积沉降引起,文昌组—恩平组欠压实段主要由沉积作用、高地热值和生烃作用共同引起,后者为有效生油段;惠州凹陷新生界地层砂岩不存在超压。

Abstract:

In order to find out the relationship between the mudstone compaction in Cenozoic Strata and the generation and accumulation of hydrocarbon in Huizhou Depression, Pearl River Mouth Basin, characteristics of mudstone compaction were analyzed, genesis of undercompaction was discussed based on maximum pyrolysis temperature and hydrocarbon generation index. The results showed that three different types of compactions in longitudinal direction were rapid compaction in shallow layer, normal compaction and low amplitude undercompaction, rapid compaction in shallow layer was mainly developed in Wanshan Formation and Pleistocene Strata(less than 700 m), normal compaction was mainly developed from the bottom of Wanshan Formation or the top of Yuehai Formation to the bottom of Zhuhai Formation or the top of Enping Formation(1 800-3 200 m), and low amplitude undercompaction was mainly developed from the top of Enping Formation to Wenchang Formation(2 400-4 000 m); Huizhou Depression was divided into northeast and midwest undercompactions, northeast undercompaction developed two low amplitude undercompactions from Zhujiang Formation to Hanjing Formation and from Wenchang Formation to Enping Formation, midwest undercompaction developed one undercompaction from Wenchang Formation to Enping Formation; the undercompaction from Zhujiang Formation to Hanjing Formation caused by the high content of clay and rapid deposition, and the undercompaction from Wenchang Formation to Enping Formation was active source rock and caused by deposition, high geothermal heat and hydrocarbon generation; there was no overpressure in sandstone of Cenozoic Strata, Huizhou Depression.
