In this paper, Qaidam Basin and Liaodong Bay in China were selected as the study areas. Based on the hydrocarbon microseepage theory, the analysis of crude oil in soil in Qaidam Basin and spectral experiment of crude oil in sea water in Liaodong Bay, Hyperion hyperspectral remote sensing images were used to develop the method of oil-gas exploration. The results indicated that the area of oil-gas reservoir in Qaidam Basin could be delimited in two ways: the oil-gas reservoir can be obtained directly by the absorption bands near 1730nm in Hyperion image; and Linear Spectral Unmixing (LSU) and Spectral Angle Matching (SAM) of alteration mineral (e.g. kaolinite, illite) could be used to indirectly detect the target area in Qaidam Basin. In addition, combined with the optimal bands in the region of visible/near-infrared, SAM was used to extract the thin oil slick of microseepage in Liaodong Bay. Then the target area of oil-gas reservoir in Liaodong Bay can be delineated. 1. INTRODUCTION Oil and gas reservoirs hydrocarbon micro-leakage phenomenon is prevalently exist in theory. It is a comprehensive performance of multiple mechanisms transferring along various approaches, about 85% of oil and gas fields have the phenomenon of micro- leakage. For the existence of micro-leakage phenomenon, there are abnormal signs of hydrocarbon component and content of soil and sea surface which above the hydrocarbon reservoirs. By using remote sensed dataset, we can detect the unusual phenomenons of hydrocarbon components in the surface soil and water, and then explore the hydrocarbon content of the land and sea. “Hydrocarbon altered column” and “hydrocarbon alteration halo” which always formed in the land surface that above the hydrocarbon reservoirs become one symbol of land oil and gas exploration. The hydrocarbons that come from the micro-leakage or diffuse to the air above the land surface, or exist in the gaps between soils, or exist in the underground water, or absorbed by the mineral grain of soil, or interact with other materials and then form alternation bodies, they make the spectral characteristics of surface natural landscape abnormal which always display as soil adsorption hydrocarbon halo, haze shaped halo, res layer faded halo, low-value iron enrichment halo, clay halo, carbonate mineralization halo, and so on(Philp et al.,1982). Researches on the elaborate spectral characteristics performed by the hydrocarbons and micro-leakage halo of hydrocarbons in the land surface are the basis of theory and method of finding hydrocarbon by using the hyperspectal technology of remote sensing. Submarine hydrocarbon leakage is one of the phenomena of marine oil and gas reservoirs, and the thin film formed by the hydrocarbons is an important symbol of oil and gas reservoirs at the bottom of the sea. When abnormal range of hydrocarbons reach the status of relative saturation, hydrocarbons in the bottom of the sea continue vertical upward migration by the action of buoyancy, part of * Qingjiu Tian: Professor in Nanjing University, China. The main research direction is Hyperspectral remote sensing. hydrocarbons form hydrocarbon-rich sea water column under the role of seawater solvation, a part continue to float to the surface to form thin film, different thickness of the thin film can produce a different color, it will become silver and invisible floating oil film after a few seconds, this special floating film, in theory, is not visible(Almond et al., 2000). The oil layer formed by the stable distribution of the sea floating film above the oil and gas reservoirs leakage source affect the electromagnetic radiation characteristics of sea surface, and thus can be detected by hyper spectral remote sensing technology. In order to make use of the information of hydrocarbon micro- leakage of the land surface and sea surface to retrieve the spatial distribution of oil and gas using hyper spectral remote sensing. First we should have a better understanding about the land surface hydrocarbon information of the micro-leakage and its alteration mineral as well as spectral characteristics of sea surface oil film. Early due to the limitations of spectral resolution of multispectral sensors, it is difficult to achieve the direct detection of the hydrocarbon information of land surface and sea surface film type; it becomes possible from the air to detect land surface and sea surface oil and gas hydrocarbon information because of the development of hyper spectral imaging spectrometer. Thus probing terrestrial and submarine tectonic region or local trap oil and gas, which can directly or indirectly, exploratory oil and gas reservoirs and delineate the oil and gas drilling target to achieve rapid, large area to find oil purpose, The domestic and foreign scholars have a more unified understanding of hydrocarbons of the land surface oil and gas. The absorption characteristics of oil and gas reservoirs micro leakage to land surface oil and gas hydrocarbons was mainly in the 1720-1750nm, 2310-2350nm wavelength (Cloutis et al., 1989). The absorption feature are stronger at 2310-2350nm, but there is overlap with other mineral absorption features (such as
