摘要:

松辽盆地长岭断陷深层具有丰富的天然气资源,应用含油气系统模拟方法重新进行了评价,深层天然气地质资源量为1.14×1012~1.71×1012 m3,中值为1.42×1012 m3。烃类气和CO2气具有分区分布的特点,其中断陷西部为CO2气富集区,断陷中部为CO2气和烃类气混合气区,断陷东部主要为烃类气富集区,局部为CO2气富集区。烃类气的分布主要受烃源岩分布的控制,高含CO2气的分布主要受火山岩和基底大断裂的控制。综合评价认为长岭断陷可划分5个勘探区带,Ⅰ类有利区带1个、Ⅱ类较有利区带3个、Ⅲ类非有利区带1个,其中Ⅰ类和Ⅱ类区带是下一步勘探部署的主要方向。

Abstract:

The deep beds of Changling fault depression is characterized by rich natural gas which can reach from 1.14×1012  to 1.71×1012 m3(the average value is 1.42×1012 m3) according to the results of petroleum system simulation. The hydrocarbon gases and CO2 are distributed in different areas: the east part of the depression is rich in hydrocarbon gases; the west part is rich in CO2; the middle part is rich in the both kinds of gases. The distribution of hydrocarbon gases are controlled by source rocks, while the CO2is closely related to the volcanic rocks and major basement faults. The comprehensive evaluations show five favorable regions, among which one is belong to typeⅠ, three belong to type Ⅱ, one belong to type Ⅲ. The typeⅠand type Ⅱ are the favorable regions to explore for the next step.

Key words: Changling fault depression, deep bed, volcanic rock, gas resource evaluation, Songliao Basin
