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.
