摘要

断裂对油气的运移、聚集以及油气藏的进一步分配起着重要的控制作用。根据腰英台区块三维地震资料及钻井资料揭示,该区块断裂十分发育,共发育四大类型断裂,大部分断层走向为NNW向,少量为SN向,断层产状较陡,是油气运移的重要通道,同时控制着局部构造圈闭的形成,并为岩性圈闭提供侧向遮挡条件。研究区发育三种油气藏类型,分别为断层—岩性油藏,断鼻油藏、岩性油藏,其中以反向断层—岩性油藏为主。
Faults play an important role in HC migration,accumulation and reservoir distribution.The 3D seismic and well data show very well developed fault system in Yaoyingtai block.Four types of faults have been identified.Most of the faults trend in NNW,few of them in NS.The fault are very steep,being important HC migration pathways.At the same time,the faults control the development of local structure traps,and can provide lateral barrier for the lithology trap.Three types reservoirs are developed in the study area, including fault-lithology reservoir,faulted nose reservoir,lithology reservoir,of which reverse fault-lithology reservoir is dominated.
