calcite). It requires careful processing and analysis as diagnostic spectral feature of oil and gas hydrocarbons extracted, at diagnostic absorption features is weaker at 1720-1750nm. In order to effectively detect, we need high performance hyper spectral remote sensing instruments. Combing with the hydrocarbon alteration minerals (e.g.: kaolinite, illite, etc.) hyper spectral extraction models, we can also indirectly identify the target filed of land oil and gas reservoirs by using hyper spectral remote sensing technology. After hydrocarbons that naturally leaked from the undersea oil and gas reservoirs rise above the water, it will form a thin film in the sea surface, and then gradually spread to a thinner film layer. At present, the description of oil film is based on a series of changes of oil film in shape and hue, such as strip (Streamer), silver (Silver sheen) (Foudan et al., 2003) and so on, but it also need to distinguish oil films according to the variation of the spectrum of the film to facilitate the hyper spectral remote sensing exploration of oil slicks. U.S. West Virginia University successfully detected oil and gas microleakage of California, Santa Barbara coast, and found several oil and gas fields between 1998 and 1999 by delineating the distribution of the hydrocarbon leakage of mineral alteration on surface through the AVIRIS Airborne Hyperspectral Imager with 224 bands (Heather, 2003). U.S. Geosat Committee detected the process of hydrocarbon leakage and migration on Australia's Northwest Ocean basins in 2001 by utilizing Probe-1 Hyperspectral Imager with 128 bands, then found several sea thin films with the length about 5-30 meters long sea thin films, and interpreted the distribution and transport of the oil film(Ellis et al, 2001) The GEOSCIENCE Company in Australia detected the process of hydrocarbon leakage and migration on Australia's Northwest Ocean basins in 2001 by utilizing HYMAP airborne hyperspectral remote sensing technology with 128 bands, then found several very thin oil films distribution areas on sea which were formed by the hydrocarbon microleakage of oil and gas undersea, and interpreted the distribution and transport of the oil film (William et al., 2002). After that, they successfully detected the surface hydrocarbon leakage and three undersea hydrocarbon microleakage reservoirs at offshore waters of USA California, Santa Barbara In 2003 by utilizing HYMAP Airborne Hyperspectral Imager with 128 bands which was developed by Hyvist Company in Australian, and combining with the effective identification and semi-quantitative analysis of components of hydrocarbon leakage oil and gas (Horig et al., 2001). This article mainly researched the land and offshore oil and gas exploration of Qaidam Basin and the Liaodong Bay marine in China by combining with the spectrum of indoor and outdoor observation experiments and using of satellite HYPERION hyperspectral remote sensing technology. 2. REMOTE SENSING DETECTION METHOD OF QAIDAM BASIN RESERVOIS 2.1 Study Area and Hyperion Image Description SeBei gas filed in the eastern of Qaidam Basin, which located in northeastern of Tibetan Plateau, was chosen as study area. The Geological condition is Saline Lake, saline soil and salt rock. In addition, the district structure is quaternary. The mainly lithology is dark grey sandy shale, with a small part of clay siltstone and brown carbonaceous mudstone. Most of the International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XXXIX-B7, 2012 XXII ISPRS Congress, 25 August — 01 September 2012, Melbourne, Australia surface is covered with floury soil and salty sand soil. Groundwater is shallow, the content of salt easy to dissolve is high, much of that is ultra chlorine saline soil, and part salty soil (Palmer et al., 1999; Palmer et al., 1994). Accordingly, the vegetation in this area is sparse, and has less community composition, simple structure and low coverage. It is very suitable to explore oil and gas using hyperspectral remote sensing images for this area. A sight of Hyperion hyperspectral image acquired on August 11, 2005 was selected in the study, and its coverage was shown in Figure 1(O Hyperion Image Copyright 2005). The image coverage is within the scope in favour of developing gas, and the lower image covers most SeBei-2 gas field, lower of which is marsh, while the upper image is Hump mountain anticline structural belt. Hump Mountain and SeBei-1 gas field are respectively located in the upper and lower image. Meanwhile, we can identify clearly a small amount of cloud and cloud shadows. 2.2 Spectrum Experiment and Analysis of Petroleum Hydrocarbon in Soil We measure the reflectance spectrum of soil with different content of oil in the lab, and analyses the sensibility to spectral response and spectral feature of crude oil in soil. Spectrometric instrument is Field Spec ASD field spectrometer produced in American spectrum Device Company. Spectral range from 350 to 2500nm, with a spectral resolution of 3nm(350-1000nm)and 10nm(1000-2500nm).Putting dry Qaidam soil samples weight of 100g into plastic disc with diameter of 10cm and depth of 2cm, floating with glass bar, and measuring soil spectra without oil and water. Pouring the soil whose spectra had been measured into glass bottle, taking crude soil at a volume of 0.5ml into the bottle using injector, putting the cap on the bottle, shake hardly until crude oil and soil fully mixing, and then putting the soil back the disc and floating, and measure the spectra. Determine repeatedly spectra of soil whose volume dose are respectively 1ml, 1.5ml, 2ml, 2.5ml, 3ml, 3.5ml, 4ml, 4.5ml, 5ml, 5.5ml, 6ml, 6.5ml, 7ml, 7.5ml, 8ml, 8.5ml and 9ml . Measuring the spectrum of soil with different content of crude oil for five times, taking the average to mapping, and then comparative analyzing. As shown in Figure 1, with the increasing of the content of crude oil in soil, reflectance spectra curve present the following features: (1) the reflectance of whole spectrum curve is lower and lower; (2) the decrease of reflectance value of overall spectrum curve is more and more slowly; (3) gradually increased the double absorption peak feature occur around 1748nm, the primary peak around 1726nm, and the secondary around 1761nm, and their feature are more and more obvious; (4) gradually increased the double absorption peak feature occur around 2330nm, and their absorption depth increased gradually, primary and secondary peak feature is not obvious. Double absorption peak feature around 1748nm and 2330nm diagnosing that whether the soil contains oil hydrocarbons (Cloutis et al., 1989; Ellis et al., 2001). As shown in Figure 1, the peaks are located at 1670nm and 1748nm, around 1748nm. The primary absorption of the valley at 1726nm begins to occur when the content of crude oil in soil is up to 1.5ml/100g. As COs’ in soil at 2350nm generates the absorption feature that wide at left but narrow at night (Foudan et al., 2003), the absorption peak composing of three bands at 2330nm, 2348nm and 2348nm has already existed before adding crude oil. Moreover, with the increasing of the content of crude oil in soil, the reflectance values at 2308nm and 2349nm tend to be equal.
