| 摘 要： | 塔里木盆地满西地区石炭系东河砂岩主要发育于滨岸沉积体系和强制海退体系域,沉积砂体表现为逐级下降的楔状体。东河砂岩沉积期间,其滨岸环境以高能砂质滨岸和高能砾质滨岸居多,泥质滨岸极少见。东河砂岩有利储集层的主控因素是岸线迁移与相带展布。油气运移条件和优质储集层的分布决定了有利勘探区带。油气储集体分布预测应该依据强制海退体系域楔状体随岸线迁移的分布规律展开。在沉积层序分析和储集体评价的基础上,结合油气勘探现状和构造圈闭分析,初步确定塔里木盆地满西地区有3个石油勘探有利区带。经钻探实践证实,依据这一思路可以获得油气大发现。

| Abstract: | The Donghe Sandstone of Carboniferous in the Tarim Basin were mainly developed in the shoreline sedimentary system and the forced regressive systems tract.The sedimentary sandbodies show a set of downstepping prograding wedges.During the deposition of Donghe Sandstone,the shoreline environment was dominated by high-energy sandy and pebbly shore deposits and few muddy shore sediments.The main controlling factors of potential reservoirs in the Donghe Sandstone are shifting of shoreline and facies distribution.Oil and gas migration conditions and distribution of high-quality reservoirs determine the potential belts for oil exploration.The prediction of oil reservoir distribution is based on the distribution pattern of the forced regressive systems tract wedges with the shifting of the shoreline.On the basis of sedimentary sequence analysis and reservoir evaluation combined with the current petroleum exploration status and structural traps analysis,the authors suggested three potential belts for oil exploration in the Manxi area of the Tarim Basin.The subsequent drilling confirmed that significant discoveries could be made according to this idea. |
