| 2 | 塔里木盆地天然气中氮地球化学特征与成因显示文摘通过统计分析塔里木盆地103个天然气样品,发现塔里木盆地天然气主要存在两种成因类型,即油型气和煤成气,且氮气含量在油型气中明显高于煤成气。在台盆区产自古生界地层的塔中、东河塘、哈得和中生界的轮南地区为异常高氮气天然气,氮气含量大于20%;新生界地层与塔西南和库车坳陷的中生界地层产出的天然气氮气含量最低(<5%),主要为煤成气;塔北地区,天然气氮气含量变化较大,低含量氮气主要为煤成气,而高氮气含量天然气为油型气,在高氮气含量的油型气中,不同热演化阶段氮气来源不同,其含量也不相同。雅克拉天然气高氮气含量可能是来源于高演化形成的氮气与少量深部气体的混合。 | 刘全有 戴金星 刘文汇 秦胜飞 张殿伟 | 2007 | 石油与天然气地质2007，28，1： | 17 |
| 3 | Quantitative studies of hydrocarbon loss of the Silurian bitumen sandstone in the Tarim Basin显示文摘The evolution of Tarim Basin experienced several tectonic movements,of which Caledonian movement caused a serious damage to reservoirs of Silurian. The earlier reservoirs size and the later hydrocarbon loss are two key factors to exploration prospect of Silurian. On the basis of net thickness of bituminous sandstone and recovery coefficient of crude oil converting to bitumen,the scale of the hydrocarbon loss of palaeo-accumulation in bitumen sandstone of Silurian was calculated (86.30×108t). The deter-mination of net thickness of bitumen sandstone was completed mainly by several methods,such as physical property demarcation,observing lithology,grains with oil inclusion (GOI) technology,and quantitative grains fluorescence (QGF) technology. The samples of black sandstone and white sand-stone were collected and compared by means of the methods mentioned above. The results showed that there was little hydrocarbon,or none,in the white sandstone. The recovery coefficient was ob-tained by the analyses of plentiful physical parameters of crude oil and bitumen sandstone,based on the hypothesis that nonhydrocarbon compounds and bitumen were invariable in the process of bitu-men forming. The calculated result,which is more scientific and actual,indicates the exploration pros-pect is more promising in Silurian of the Tarim Basin. | JIANG ZhenXue1,2,PANG XiongQi1,2,LIU LuoFu1,2,WANG XianDong3,ZHANG Jun4 & LI HongYi1,2 1 Basin and Reservoir Research Center,China University of Petroleum,Beijing 102249,China 2 State Key Laboratory of Petroleum Resource and Prospecting,China University of Petroleum,Beijing 102249,China 3 Research Institute of Exploration and Development,Daqing Oilfield Company Ltd,Daqing 163712,China 4 Petroleum Exploration and Production Institute of SINOPEC,Beijing 100083,China | 2008 | Science China Earth Sciences2008，51，S2： | 3 |
