塔里木盆地原油裂解气资源估算

在前人研究成果的基础上, 采用正、反演相结合的方法, 对台盆区原油裂解气资源与分布进行了研究。对台盆区原油裂解气资源反演估算。结果表明, 其约占台盆区天然气总资源量的40%~52%; 根据油气生成运聚理论及油气系统理论, 首次采用盆地模拟正演方法对台盆区原油裂解气资源进行了估算, 结果表明, 其约占台盆区天然气总资源量的49%.正反演综合结果表明, 塔里木盆地台盆区原油裂解气资源约占其天然气总资源量的40%~52%, 具有丰富的资源前景; 原油裂解气主要分布在塔东地区和麦盖提斜坡, 其次为塔北和塔中地区。

Estimation of Oil Cracked Gas Resources in Tarim Basin

On the basis of previous studies, this paper presents the inverse estimation of oil cracked gas resourcesaccounting for 40%～ 52% of the total natural gas resources in ancient cratonic area in Tarim basin, and the forward estimation of it accounting for 49% of the total, according to theories of petroleum generation, migration and accumulation as well as petroleum system. The results show that Tarim basin is rich in oil cracked gas resources, mostly distributing in Tadong (eastern Tarim)area and Maigaiti slope, partly in Tabei (northern Tarim)and Tazhong (centre Tarim)areas.
