Fluid inclusions were studied in rocks from different wells from the Barnówko–Mostno–Buszewo (BMB), the largest oil field in Poland and from the Lubiatów field. Sampling was performed at depths between about 3120–3220 m and 3221–3256 m, respectively. Different minerals (dolomite, calcite, anhydrite, quartz) reveal the presence of aqueous (AQFI) and hydrocarbon (HCFI) inclusions, the differentiation of which was checked by UV fluorescence and microthermometry. Inclusions occur in different abundances and are of variable character. The microthermometric studies of fluid inclusions resulted in the determination of temperatures of eutectic melting, ice melting, and homogenization. Based on the results obtained, three types of inclusions have been found. Two-phase non-fluorescent inclusions (AQFI) contain brines of differentiated salinity (from about 6 to 10 and from about 17 to 22 wt% NaCl equivalent). Two-phase fluorescent inclusions (HCFI 1) contain light mature oil of paraffin character. The oil is characterized by API gravity of about 41–42 degrees. Small one-phase non-fluorescent inclusions (HCFI 2) that homogenize in deep freezing contain methane with admixtures. The abundance of inclusions varies, depending on the mineral or well. They have been discussed in the context of hydrocarbon migration and accumulation.

流体包裹体在石油盆地识别中的应用-以波兰为例

在波兰最大的油田Barnówko-Mostno-Buszewo（BMB）和Lubiatów油田不同井的岩石中研究了流体包裹体。分别在大约3120–3220 m和3221–3256 m的深度进行采样。不同的矿物（白云石，方解石，硬石膏，石英）显示出水相（AQFI）和碳氢化合物（HCFI）夹杂物的存在，并通过紫外荧光和微量热分析法对其进行了区分。夹杂物以不同的丰度出现并且具有可变的特征。流体包裹体的显微热学研究导致确定了共晶熔化，冰融化和均质化的温度。基于获得的结果，发现了三种类型的夹杂物。两相非荧光夹杂物（AQFI）包含不同盐度的盐水（约6至10重量％和约17至22重量％NaCl当量）。两相荧光夹杂物（HCFI 1）含有石蜡性质的轻质成熟油。该油的特征在于API重力约为41–42度。在深度冷冻中均质的小单相非荧光夹杂物（HCFI 2）含有甲烷和混合气体。夹杂物的丰度根据矿物质或井的不同而不同。已经在烃运移和聚集的背景下讨论了它们。在深度冷冻中均质的小单相非荧光夹杂物（HCFI 2）含有甲烷和混合气体。夹杂物的丰度根据矿物质或井的不同而不同。已经在烃运移和聚集的背景下讨论了它们。在深度冷冻中均质的小单相非荧光夹杂物（HCFI 2）含有甲烷和混合气体。夹杂物的丰度根据矿物质或井的不同而不同。已经在烃运移和聚集的背景下讨论了它们。
