摘　　要：JL2井西三维二叠系上乌尔禾组是中拐凸起主要产油层段之一,但对其储层分布规律、砂体展布范围认识不清。本文应用GeoEast地震储层综合预测技术,开展了储层预测、多属性模式识别、油气检测以及沉积相研究,落实了高效、规模储量区块。研究结果表明,JL2井西三维二叠系上乌尔禾组两个沟槽带是有利储层发育带,其内部断层发育,沟通油气运移通道的同时有效改善了储层物性。将GeoEast地震储层综合预测技术无监督模式识别方法应用于地震相划分、储层识别和油气检测,对储层进行定性分析,有效解决了地质综合研究中一些复杂的地质问题。The upper Wuerhe Formation of Permian in the west of well JL2 3-D is one of the main oil-producing zones in Zhongguai Uplift,but its reservoir distribution and sandbody distribution are not well understood.In this paper,GeoEast seismic reservoir comprehensive prediction technology is used to carry out reservoir prediction,multi-attribute pattern recognition,oil and gas detection and sedimentary facies research in order to implement blocks having efficient and large-scale reserves.The results show that the two trench zones of the upper Permian Wuerhe Formation in the west of JL2 well are favorable reservoir development zones,and the internal faults are well developed,which can communicate the hydrocarbon migration channel and improve the reservoir physical properties effectively.GeoEgast seismic reservoir comprehensive prediction technology is used in unsupervised pattern recognition method for seismic facies division,reservoir identification and oil-gas detection,to qualitatively analyze the reservoir.Some complex geological problems in the comprehensive geological research have been effectively solved.
