【摘要】 本文以沉积学、岩石学、测井地质学、油气地球化学等学科的基本理论和观点为指导，综合运用地震、测井、录井、岩心和油气地球化学资料，对准噶尔盆地西北缘进行构造、沉积和地球化学等多学科地质综合研究。着重分析了西北缘的沉积岩相分布特征和规律，研究了西北缘沉积相展布的控制因素以及沉积相和油气分布的关系。分析了西北缘不同地区的油藏地球化学特征，研究了西北缘的油源对比和油气成藏演化特征。在综合研究沉积相和油藏地球化学的基础上，得出西北缘的油气储量主要受扇体(扇三角洲、水下扇和冲积扇)控制，并且具有多期成藏特征的认识。在此基础上评价和预测了本区的勘探领域。更多还原

【Abstract】 Guided by new theories and viewpoints of sedimentology, petrology, log-geology, oil and gas geochemistry, the paper used extensive data including seimic, log, cores, oil samples and oil-gas geochemistry in order to make an integrated research on the northwest margin of Zhunger Basin .It emphasized on the distribution and laws of sedimentary facies,the controlling factors of facial distribution and relations between oil and sedimentary facies. It also made detailed analyses of geochemical character of oil pools in various district. The paper also studied the relationship between oil-resources correlation and evolutionary traits of oil pools. After integrated studies on sedimentary facies and geochemical character in this area,it is concluded that the oil and gas reserves in this district are mainly controlled by fans such as fan-detal ,denthic fans and alluvial fans.and that pool foration in the area under study is of multi-phase character. So the exploration domains are evaluated and anticipated.更多还原
