复杂断块圈闭识别与应用研究——以南阳凹陷魏岗鼻状构造带为例

Identification and Application Research of Complex Fault-Block Trap—Take Weigang Nose Structure Zone in Nanyang Depression as an Example

为在南阳凹陷魏岗鼻状构造带上寻找新的出油点和储量增长点,根据其构造破碎、断块复杂、储层物性纵横向变化大、含油高度小、含油条带窄等特点,借助人机联作一体化解释软件,应用储层标定、小断层识别、三维可视化、变速成图、储层精细描述与定向井等技术,围绕油田勘探开发面临的问题进行有针对性的研究。其研究方法在南阳凹陷魏岗鼻状构造带取得良好的地质效果。

In order to find new oil point and increasing reservoir volume on Wei Gang nose structure,we spread out the research project about exploration and development of oil field according to the characteristics of cracking structure,complex fault block,low oil column,variable reservoir and limited oil band.At the same time,we used a series of techniques as interactive interpretation software,reservoir calibration,small fault bed identification,3D visualization,variable velocity map,reservoir description and directional well.Good geological effect has been abtained on this nose structure.
