摘要

摘要:
断陷盆地新近系的成藏规模与深层油气汇聚及立体输导体系息息相关，断陷盆地新近系源外目标圈闭油气充注的差异性是新近系目标研究中需要重点关注的问题。以渤海海域庙西北凸起东侧陡坡带为例，分析了陡坡带油气汇聚体系组成要素，通过断层输导能力评价划分了优势充注段，进而在断层充注段控制下开展了油气运移模拟。研究表明：(1)陡坡带汇聚体系由深层聚烃砂体、边界大断层、浅层晚期断层3个部分组成。(2)汇聚体系中3个部分的各自优势汇烃要素相互作用组成主要运移路径，最终体现在与目标圈闭搭接的断层充注段上；庙西北凸起东侧主干运移断层中段为强充注区，北段为中等充注区；次级运移断层中4，6，8号断层发育强充注段，1，2，11号断层发育中等充注段。(3)构造层运移模拟发现庙西北凸起东侧陡坡带中段发育油气聚集区，东侧发育2条主要运移路线，同时南侧发育1条主要运移路线；3号典型砂体发育4个汇聚区，其中汇聚区C为汇聚能力最强区域。研究成果可为目标区井位部署提供参考，技术方法可为油气汇聚成藏分析提供技术支持。

Abstract: Objective
The size of Neogene reservoir formation in rifted basins is closely linked to deep oil and gas accumulation and three-dimensional transport systems.
Methods
This study examines the differential oil and gas charging issues associated with target traps in Neogene fault basins. Using the eastern steep slope of the Miaoxibei Uplift in the Bohai Sea as an example, we analyze the components of the oil and gas accumulation system in steep slope zones by evaluating fault conduction capability and dividing the dominant injection segments. Subsequently, oil and gas migration simulations are conducted under the control of the fault injection section.
Results
The research findings are as follows: ① The accumulation system in the steep slope zone consists of deep hydrocarbon accumulative sand bodies, large boundary faults, and late shallow faults. ② The dominant hydrocarbon sinks in the three parts of the accumulation system interact with each other, forming a dominant migration path that is reflected in the overlapping fault charging section with the target trap. The middle section of the main migration fault on the east side of the Miaoxibei Uplift is a strong charging area, while the northern section is a medium charging area. Among the secondary migration faults, faults 4, 6, and 8 have developed strong charging sections, while faults 1, 2, and 11 have developed medium charging sections. ③ Structural migration simulations reveal that the oil and gas accumulation area develops in the middle of the steep slope zone in the east of the Miaoxibei Uplift, with two main migration routes in the east and one in the south. The typical sand traps in fault No. 3 have developed four accumulation zones, with accumulation zone C being the most significant.
Conclusion
In conclusion, these research findings can serve as a reference for well deployment in target areas, and the technical methods employed can provide support for hydrocarbon accumulation analysis.
