油气储层流体包裹体包含着油气成藏时丰富的微观地质信息。采用LABHR2VIS LABRAM HR800 型显微激光拉曼光谱仪和LINKAM THMS 600型冷热台,对鄂尔多斯盆地苏里格大气田上古生界储层流体包裹体样品进行测试分析。结果表明,苏里格大气田上古生界储层流体包裹体分布有低饱和烃类包裹体、沥青质烃类包裹体、饱和烃包裹体、CH4包裹体、CO2包裹体和纯盐水包裹体6种类型,其中含CH4包裹体、CO2包裹体和含烃包裹体较为丰富,占到50%以上。通过对流体包裹体的激光拉曼分析和均一温度测试结果分析,反映苏里格大气田成藏时曾有丰富的不同成分组成的烃类流体充注,与烃类包裹体同期的盐水包裹体均一温度分布范围为100~180℃,主峰温度在140~150℃之间。依据包裹体均一温度的实测结果,结合沉积埋藏史和古地温史,推算出苏里格气田上古生界天然气主要充注成藏期为晚侏罗世—早白垩世(150~100Ma)。

Much microscopic geological information of oil and gas reservoirs can be obtained from the reservoir fluid inclusions.Fluid inclusion samples from the upper Paleozoic of the Sulige large gas field were tested and analyzed in this paper using the LABHR2VIS LABRAM HR800 laser Raman spectrometer and LINKAM THMS 600 cool-heating instrument.The results showed that the fluid inclusions of the upper Paleozoic Sulige large gas field included six types of the low saturated hydrocarbon inclusion,asphaltic hydrocarbon inclusion,highly saturated hydrocarbon inclusion,the CH4-rich inclusion,the CO2 inclusion and aqueous inclusion.The CH4-rich inclusion,the CO2inclusion and the hydrocarbon-bearing inclusion were the main types of these fluid inclusions,which were more than 50%.The data of the fluid inclusions measured by homogenization temperatures and analysed by laser Raman showed that rich hydrocarbon fluids of different components were charged in the Sulige large gas field at gas accumulation period.The homogenization temperatures of aqueous inclusions coexisted with hydrocarbon inclusions were ranged from 100℃ to 180℃,and the main peak temperature was 140-150℃.According to the measured homogenization temperatures of fluid inclusions and combined with the burial evolution and paleo-temperature history,the result suggested that the main gas accumulation period of the upper Paleozoic reservoirs in the Sulige large gas field was occurred at the late Jurassic and early Cretaceous (150-100Ma).
