| 摘 要： | 在层序地层格架的基础上,结合区域地质概况和前人研究成果,充分运用重矿物的组合特征、岩心观察描述的岩性序列特征、岩性及电性的横向变化特征、地震反射特征,结合砂岩厚度、砂地比的平面展布规律,对南襄盆地泌阳凹陷东南部古近系渐新统核桃园组的物源方向进行了研究。结果表明,泌阳凹陷东南部主要发育5个物源,其中主要物源有1个,为泌150—泌285井区的平氏物源,该物源对研究目的层各个层序的西南部沉积砂体均有控制;次要物源有4个,即泌102—泌239井区的杨桥物源、正南方向的泌151—泌251井区的魏庄物源、东南方向泌129井区的栗园物源、以及东北方向的泌319井区的栗园东北物源,这些次要物源仅对部分层序的沉积砂体有控制作用。

| Abstract: | Based on the sequence stratigraphic framework,combined with regional geology and results of former researchers,through analysis of data of heavy mineral combinations,lithology sequence of core,lateral change of lithology and logging curve‘s characteristics,seismic reflectors,sandstone thickness and content,the provenances of the Paleogene Oligocene Hetaoyuan Formationin in southeastern Biyang Sag of Nanxiang Basin were analyzed.The result showed that: There existed five provenances in Biyang Sag;The main provenance,Pingshi Provenance(Well B150-Well B285 area),controlled the southwestern sandbodies;The other four provenances are Yangqiao Provenance(Well B102-Well B239 area),Weizhuang Provenance(Well B151-Well B251 area)from the south,Liyuan Provenance(Well B129 area)from the southeast and the Lishuwa Provenance(Well B319 area)from the northeast. These minor provenances just influenced sedimentation of some sequences. |
