原油

To the concrete two-phase flow -crude oil, its temperature, speed and capacitance value are measured by flat capacitance sensors, FLUKE RLC instrument and other auxiliary appliance. Assessing the characters of crude oil and predicting the solidifying point is the result of using fuzzy information arithmetic.

Then,different kinds of wellhead sealing sets and sealing materials are designed and worked out.

原油中的胶质是影响原油粘度的主要物质，胶质含量越高原油粘度越大。

摘 要：辽河曙光油田杜84块超稠油油藏的储集层胶结非常疏松，原油中沥青质、胶质含量高达45.7%，原油黏度对温度敏感性强，油藏温度45℃时原油黏度高达22×104mP 。

Two kinds of high alcohol acrylates were prepared by octadecyl alcohol and hexadecyl branched alcohol,respectively.The polymers of depressants were prepared by maleic anhydride-styrene-higher alcohol acrylates.By using these depressants,the pour points of the Liaohe crude oils were lowered form 30℃ to 20℃.

分别采用碳十八直链醇、碳十六支链醇与丙烯酸合成烷基酯，将烷基酯再与顺丁烯二酸酐、苯乙烯聚合制备的三元共聚物，对辽河油田的高凝原油的降凝效果进行了评价，实验发现这两种聚合物对凝固点为30℃原油都具有较好的效果，降幅可达10℃左右，但对凝固点为41℃的原油较差分别为3℃和6℃。

The test result showed that the pour point of Jianghan crude oil might depress from 28 ℃ to 13 ℃ when styrene∶maleic anhydride∶octadecyl acrylater was 1∶3∶3, preheated temperature of the crude oil was 60 ℃, and addition of the terpolymer was 300 mg/L.

研究表明，当苯乙烯、马来酸酐、丙烯酸十八烷基酯三种单体摩尔比为1∶3∶3，原油预热温度为60 ℃，三元共聚物在江汉原油中加量为300 mg/L时，此三元共聚物可使江汉原油的凝固点从28 ℃降到13 ℃。

In order to identify the disputed oil source in Suaiqo-Wen'an region, Baxian sag, Jizhong depression, on the basis of source rock evaluation and oil-to-source correlation in this region, we recognized the typical Palaeogene oil and Carboniferous-Permian oil viz. two-ends oil, and established effective identification index from detailed analysis of biological marker, separation of nitrogen containing compound, stable carbon isotope and also make reference to the foreign studies on coal derived oil.

针对长期以来冀中坳陷坝县凹陷苏桥-文安地区存在的原油来源争议的问题，在对本区烃源层评价认识和油源对比的基础上，运用生物标志物精细检定、含氮化合物的分离检定、稳定碳同位素分析等技术手段，并结合国内外煤成油的研究成果，划分出了坝县凹陷典型的下第三系原油和石炭-二叠系原油，即两类端元油，并提出了有效的判识指标。

By comparison among concentration of nitrogen compounds, relative contents of pryyolic N-H shielded carbazoles and parameters of C21-/C22+、Pr/nC17 , the results show that slight biodegradation has little effects on the relative contents and distribution of pyrrolic nitrogen compounds, but has certain effect on its concentration.

根据2类原油中含氮化合物浓度、屏蔽型含氮化合物的相对含量与反晕原油生物降解的地化参数C21-/C22+、Pr/nC17等指标的对比研究，发现生物降解作用对该区原油中含氮化合物的相对含量及其分布影响不显，运移作用仍然是造成含氮化合物分馏的主要因素。

The first type is E s 1 and E f 3 member oil, which is derived from E f 2 member source rock of deep sag. The second type is E f 1 member oil which is derived from E f 1 member source rock of deep sag. Integrated with the analysis of pyrrolic nitrogen compounds and its parameters, Beihanzhuang E f 3,/E f 1 and E s 1 member oil migrated from deep sag to Beihanzhuang structure belt apparently.

研究结果表明，北汉庄油田的原油可以划分为2类：第一类原油分布于垛一段与阜三段，主要来源于深凹带阜二段烃源岩；第二类原油分布在阜一段，主要来源于深凹带阜一段烃源岩。

Compared with the unblended Daqing crude,there was a big influence on the production and performance of lubricating base oil s.

与大庆原油相比，大庆原油混兑8%俄罗斯原油后，对润滑油基础油的生产和质量均产生了较大影响。

In this paper,by simulating different indoor and outdoor experiments of the crude oils in the different weathering environment of summer and winter,and using fluorescence spectrometry,Comparison and analysis of spectra from oils of unweathered and at different weathering times are experimentalized(crude oils from Kuwait and Saudi- Arabia,which are both light crude oils),which could identify the two similar oil species,without taking into account the biological degradation,wind speed,as well as factors such as the role of the waves,and the impact of factors,then how the fingerprints will be changed in the law have been found.

本文通过模拟不同原油在室内和室外的夏、冬两季的风化实验，运用荧光光谱法，对未风化油品和不同风化时间的油品(科威特原油和沙特阿拉伯轻质原油)进行谱图对比分析，鉴别两种相似油种，在不考虑生物降解、风速以及海浪等因素的影响，找出油指纹随风化影响因素的变化规律。
