【摘要】 文中报道在实际储层温压条件下(150℃,40MPa,大约4km深度)成功合成了碳酸盐岩烃类包裹体。通过对合成烃类包裹体的显微观察、荧光分析和傅里叶变换红外光谱分析,证实合成了烃类包裹体,且与真实储层中的包裹体具有相似特征,探讨了油水不混溶条件下的流体包裹体捕获机制。实验研究给出4点重要启示:(1)油水不混溶是造成烃类包裹体和水溶液包裹体分带的主要原因;(2)油气快速成藏过程可以被流体包裹体记录;(3)实际储层温压条件下,合成烃类包裹体实验研究有望为储层包裹体分析提供依据和标准;(4)人工合成烃类包裹体为研究含油气条件下储层水-岩作用机理提供了一种有效手段。更多还原

【Abstract】 We have successfully synthesized hydrocarbon-bearing inclusions in carbonate at the temperature and pressure of 150 ℃ and 40 MPa, which are near the condition of natural reservoir underground 4 km.All synthetic hydrocarbon-bearing inclusions have been analyzed by microscope and micro-fluorescence and fourier transform infrared spectroscopy.The results show that the synthesized hydrocarbon-bearing inclusions are very similar to those in real reservoirs.Our experiments give us four important insights, including: (1) immiscibility of oil and water is the main reason for hydrocarbon-bearing inclusions and aqueous inclusions distributed in different fractures; (2) rapid accumulation of oil and gas can be recorded by fluid inclusions; (3) the study of synthetic hydrocarbon-bearing inclusions at the temperature and pressure of real reservoir will offer references and standards for the analysis of fluid inclusions in reservoirs; (4) experiment of synthetic hydrocarbon-bearing inclusions is a good method for understanding the mechanism of oil-water-rocks inter-reaction in reservoirs.更多还原
