| 摘 要： | 油气在地下深处以侧向运移为主,当集中到油气储层之后,油气储层变成高温、强压地质梯度体。在梯度体内,油气运移方向和形式发生重大改变,油气运移由水平侧向运动变成为以微渗漏和扩散为主的垂向运动。油气在渗漏过程中与上覆地层、岩石发生以化学为主的作用。由于油气微渗漏及发生的化学作用,在油气田上方形成了一个还原环境的柱状体,并形成大量的新生矿物,致使地物电磁波谱特征和自然景观发生变化,因而在遥感图像中呈现出独特的油气微渗漏影像异常。

| Abstract: | Oil and gas move mainly in lateral way in the deep subsurface. Having accumulated in reservoir bed, the reservoir is turned into a geological gradient body with high temperature and pressure. The direction and mode of the oil and gas movement vary significantly in the gradient body, and the movement becomes in vertical way with the micro-Seepage and the diffusion in domination. Oil and gas have Chemical reation with the overburden rock. Under the condition of the chemical reaction, a pillar body with reduced geological environment can be formed above the oil and gas area, and this brings a lot of new materials and minerals, which directly influence the electromagnetic spectrum of the materials on the ground. This is the reason that the special image ano- malies on remote Sensing pictures for oil and gas micro-Seopage are showed. |
