摘　　要：准噶尔盆地西缘春风油田石炭系储层以火成岩为主,影响火成岩储层储集性能的主要因素有火成岩的岩石类型、断裂发育程度以及风化淋滤作用。利用岩心观察、岩石薄片分析,结合测井、录井、核磁等资料明确了该区火成岩的岩石类型,主要发育凝灰岩、玄武岩、安山岩、火山角砾岩等,储集空间类型以孔洞及裂缝为主;通过对地震剖面进行目标处理,利用地震相、地震属性等优化断裂组合体系,寻找断裂发育区;利用孔、渗、油气显示及试油等资料确定风化淋滤作用在纵向上对火成岩的影响,初步明确火成岩勘探的垂向深度;结合重磁等非震资料优选储层发育区。综合分析各因素对火成岩储层发育的影响,对该区火成岩勘探区域进行了评价,优选该区东北部靠近红车断裂带附近P66井区为有利火成岩储层发育区。The Carboniferous reservoirs in Chunfeng Oilfield which was located in the western margin of Junggar Basin were mainly igneous rocks.The major factors affected the performance of igneous reservoirs were rock types,faults development degree and weathering and leaching.According to the core observation and thin section analysis,combined with logging,borehole log and nuclear magnetic resonance(NMR),the main igneous rock types in the studied area were clarified,where tuff,basalt,andesite,volcanic breccia and so on were mainly grown,the type of reservoir space was mainly vugs and fractures.Through the special processing of seismic targets,seismic facies and seismic attributes were used to optimize faults combination system and search for the fault development area,the data of porosity,permeability and oil &gas shows and so on were deployed to determine the impact of weathering and leaching on the igneous rocks longitudinally,the vertical depth of igneous exploration was initially clarified and combined with gravity,magnetic data and other non-seismic data,reservoir development zones were chosen.The effect of various factors on the development of igneous rocks is comprehensively analyzed and the areas of igneous rock exploration are evaluated,it is determined that Wellblock Pai 66which is located in the northeast area near Hongche Fault is the most favorable igneous exploration zone.
