| 摘 要： | 塔里木盆地塔中地区志留系油气显示丰富,成藏条件复杂,研究其油气成藏模式对推动塔中油气勘探有重大现实意义.本文主要对志留系沥青砂和可动油气的分布特征及成因机制进行分析,总结其成藏模式.研究结果表明:塔中地区志留系可动油气主要来自寒武系和奥陶系的混源,可动油气主要存在晚海西期和喜山期两期成藏,运移以垂向运移为主,侧向有限运移;塔中地区志留系沥青砂岩主要来源于寒武—下奥陶统烃源岩,沥青砂岩为油气边运移边破坏的产物;塔中志留系油气为两期成藏、两期改造的多点垂向输导,有限侧向输导成藏演化模式.

| Abstract: | There are a lot of asphaltic sandstones that is widely distributed in Tazhong Area,Tarim Basin; however the condition of hydrocarbon accumulation is complex. It is of great practical significance to study the hydrocarbon accumulation model of Silurian strata in order to accelerate the process of oil and gas exploration in the Tazhong Area. The distribution and genesis mechanism of asphaltic sandstones and movable oil of Silurian have been analyzed,and the hydrocarbon accumulation model have further been sum... |
