砂岩油藏油-气-水不混溶包裹体特征及成因
发布时间：2019-04-11 07:20
【摘要】：对多个砂岩油藏中流体包裹体进行研究后发现,石英颗粒中普遍发育一类油-气-水不混溶包裹体。这类包裹体非均一捕获了油-水两相,表现出油-气-水三相共存、均一温度异常高、同一组合内包裹体气/液比和均一温度分布离散且无规律、气泡紧靠包裹体内壁、降温后不共结等特征。因镜下特征与盐水包裹体相近,其异常高的均一温度易对测试结果造成严重影响,仔细观察包裹体的荧光特征和降温后的共结现象能够准确地进行识别。包裹体内油相组分以沥青质为主且吸附在包裹体内壁上,反映这类包裹体的普遍发育与矿物颗粒对原油沥青质中极性组分的选择性吸附作用有密切关系。
[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.
