| 摘 要： | 石油和天然气是流体矿产,其最大特征具有运移性。构造应力与油气运移密切相关。引起地质环境、圈闭条件、应力状态改变的动力是构造应力场。盆地沉陷、隆起、断裂构造等都是不同特点的应力状态作用下的地质痕迹。高应力区围限下的低应力区,一般是有利的储油储气构造位置。本文在东海西湖凹陷中央背斜带及其邻区构造地质、石油地质研究的基础上,对平湖组、花港组、龙井组目的层在中新世晚期的应力状态进行了数值模拟,进而分析了应力场与油气运聚的关系,研究结果与构造地质、石油地质分析结论相一致,对油气勘探开发具有指导意义。

| Abstract: | Oil and gas is fluid ore with major feature of migration. Tectonic activity is closely related with hydrocarbon migration. Stress field is the power of structural deformation and movement, which causes the change of geologic environment, trap conditions and stress state. Basin subsidence, uplift, fracture are geologic trace formed by stress state with different characters. In general, the low stress area surrounded by high stress one is a favor reservoir for oil and gas migration and accumulation. The direction of maximum principal compressive stress is accordance with the direction of oil-gas migration. |

| Keywords: | stress field numerical simulation hydrocarbon migration and accumulation |
