【摘要】：對多個砂巖油藏中流體包裹體進行研究后發(fā)現,石英顆粒中普遍發(fā)育一類油-氣-水不混溶包裹體。這類包裹體非均一捕獲了油-水兩相,表現出油-氣-水三相共存、均一溫度異常高、同一組合內包裹體氣/液比和均一溫度分布離散且無規(guī)律、氣泡緊靠包裹體內壁、降溫后不共結等特征。因鏡下特征與鹽水包裹體相近,其異常高的均一溫度易對測試結果造成嚴重影響,仔細觀察包裹體的熒光特征和降溫后的共結現象能夠準確地進行識別。包裹體內油相組分以瀝青質為主且吸附在包裹體內壁上,反映這類包裹體的普遍發(fā)育與礦物顆粒對原油瀝青質中極性組分的選擇性吸附作用有密切關系。
[Abstract]:After studying fluid inclusions in several sandstone reservoirs, it is found that a kind of oil-gas-water immiscible inclusions are generally developed in quartz grains. The heterogeneous inclusions capture the oil-water phase, showing that the oil-gas-water phase co-exists, and the homogeneous temperature is unusually high. The gas / liquid ratio and the homogeneous temperature distribution of the inclusion in the same combination are discrete and irregular, and the bubbles are close to the wall of the inclusion body. The characteristics of non-cojunction after cooling. Because the microscopic features are close to that of saline inclusions, its unusually high homogeneous temperature is easy to cause serious influence on the test results. Careful observation of the fluorescence characteristics of inclusions and the co-junction phenomenon after cooling can be accurately identified. Asphaltene is the main oil phase component and adsorbed on the wall of the inclusion body, which indicates that the general development of these inclusions is closely related to the selective adsorption of polar components in crude asphaltene by mineral particles.
