孔西潜山奥陶系原生油藏成藏时期探讨

黄骅坳陷孔西潜山发现奥陶系（孔古3井、孔古7井）低产原生油藏和石炭-二叠系原生油气藏（孔古4井），油源对比结果证明，前者原油主要源于中奥陶统马家沟组灰岩，后者油气主要源于石炭系太原组及二叠系山西组煤系泥岩。根据孔古3井油藏的两期流体包裹体及储集层自生伊利石K-Ar年龄测定结果，油藏属两期成藏，第一期为晚三叠世（距今222.51～240.34Ma），第二期为第三纪，以晚第三纪为主。

砂砾岩储集层含油性解释方法

LJ地区砂砾岩地层具有岩石结构复杂，储集层非均质性强，稠油和稀油并存的特点，利用测井资料解释含油性难度很大，以地层测试资料为依据，综合利用多种测井信息，提取反映含油性变化的测井特征参数；应用测井参数交会法和测井相分析法建立有效，快速识别稠油，油层和水层的标准，测井相分析法消除了用测井单参数和两参数交会解释含油性存在的多解性，提高子解释结果的成功率，用编制的解释软件处理了LJ地区58口井的资料，解释结果与试油资料对比吻合程度较高，为砂岩储层含油性解释提供了一种有效，快速的方法，为该区先导性试验提供了可靠的依据。

Quality of Crude Fish Oil Extracted from Herring Byproducts of Varying States of Freshness

ABSTRACT: Herring byproducts were stored at 2 and 15 °C for up to 72 h. Over time, significant increases of total volatile bases (TVB), histamine, putrescine, cadaverine, and tyramine were detected. However, only tyramine and TVB levels were temperature-dependent. The level of total polyunsaturated fatty acids (PUFAs) was constant. Longer byproducts storage gave rise to an oil with higher levels of free fatty acids, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and total PUFAs, while fluorescent compounds were lower. A higher storage temperature led to oil higher in α-tocopherol and EPA levels and lower in anisidine value. Surprisingly, the oil with the highest content of PUFAs was not produced from the freshest byproducts, and oil with low oxidation products can be extracted from stored byproducts.

Retaining maximum antioxidative potency of wheat germ oil refined by molecular distillation

A process of physical refining wheat germ oil using the technique of molecular distillation (MD) is presented in this work. Wheat germ oil was obtained from the germ by solvent extraction using hexane and also by cold pressing. The oil extracted with hexane was degummed and bleached before deacidification in order to modify the parameters of phosphorus and color. The goal in carrying out the stage of physical refining by MD was to preserve the maximum amount of original antioxidative potential obtained from extraction of the crude oil. The effect of evaporation temperature of one‐stage MD on the efficiency of free fatty acid elimination was studied. The antioxidant portion was followed by means of analytic determination of tocopherols by high‐performance liquid chromatography. Tocopherol retention up to 98% was achieved in the oil extracted by pressing, and yields of up to 96% were achieved in the oil extracted with hexane.
