摘要

摘要: 在区域油气成藏条件、运聚特征研究的基础上,总结亚诺斯盆地LB区块成藏主控因素及成藏模式,探讨局部油气富集的影响因素,预测有利勘探方向.LB区块是油气运聚的优势指向区,主力储层卡沃内拉组内部发育多套储盖组合,圈闭类型主要为与正断层伴生的低幅断背斜、断鼻构造;区块油气成藏的主控因素是构造与储层,它源油气沿C7层块状砂岩侧向运移,首先在层内构造圈闭中聚集成藏,部分油气被后期断层作用垂向输导到C5层,并在该层底部紧邻断层的构造、岩性圈闭内再次聚集成藏,局部油气富集受构造背景、圈闭幅度及储层质量等因素共同控制;区内预测发育有C7层远离断层的低幅背斜型油藏、C5层断层下降盘岩性上倾尖灭型油藏.

Abstract: Based on the analysis of hydrocarbon generation, migration and accumulation, the controlling elements and pattern of reservoirs in the LB block of the Llanos Basin were summarized. The influencing factors for local hydrocarbon enrichment were identified, and favorable exploration targets were predicted. The LB block had a good potential for hydrocarbon migration and accumulation. In the major reservoir (the Carbonera Formation), multiple sets of reservoir-cap assemblages developed. Traps included faulted noses and faulted anticlines associa-ted with normal faults. Structure and reservoir were the main controlling factors of hydrocarbon accumulation. Hydrocarbon migrated laterally along massive sandstones in the C7 section of the Carbonera Formation. Firstly, they accumulated in structural traps in the C7 section, and then partially migrated upwards into the C5 section through faults and accumulated in structural and lithologic traps adjacent to the faults at the bottom of C5. Local hydrocarbon enrichment was affected by various factors, such as tectonic background, trap amplitude and reservoir quality.Low-amplitude faulted anticline reservoirs developed far away from faults in the C7 section and lithologic updip pinch-out reservoirs in the downthrown side of faults in the C5 section were predicted.
