随着世界各国"碳中和"目标的提出,传统炼油企业同时面临着巨大的碳减排环保压力和成品油市场结构调整压力,生产高端润滑油产品成为炼油企业提高利润空间的重要方向之一.传统"老三套"润滑油生产工艺因难以满足APIⅡ类、III类基础油的生产要求而逐渐被全加氢工艺所取代.在此背景下,文中以某炼油厂20×104 t/a润滑油基础油全...     

Catalytic oxidation of sulfides in lube oil cuts with organic hydroperoxides

The catalytic properties of acids and metal compounds in oxidation of sulfides in lube oil cuts of medium-sulfur crude oil by organic hydroperoxides are examined. Comparative data are reported on the effectiveness of these catalysts in the process. The activity of the catalysts was compared with respect to the depth and selectivity of conversion of sulfides into sulfoxides. __________ Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 1, pp. 38–40, January–February, 2006.     

油、水井分层动用状况研究新方法

针对注水开发的多层砂岩油田油、水井分层监测资料少、油藏分层动态分析难度大等问题,提出了一种买用的油水井分层动用状况研究新方法：以井组内注采平衡为依据,综合考虑注水井和受其影响的采油井的油层条件(油层厚度,渗透率,原油黏度)和开发条件(注采井距．生产压差,改造措施)等因素,通过平面分配系数和垂向劈分系数,合理劈分注水井的分层注水量．从而得到油井各小层的分层产液量。该方法把油、水井作为一个统一的整体,采取动静结台方式,克服了过去简单地根据油层的产能系数(有效渗透率与有效厚度的乘积)劈分油、水井的分层注水量和产液量的缺陷。大厌葡北油田37口井的现场实际资料验证,用该方法计算的水井分层吸水量和油井的分层产液量与实测吸水量和实测产液量符合率较高。表1参10

The mechanism of thermal oxidation of a hydrotreated naphthenic lube base oil at high temperature

Using KN4010 as a base stock, we monitored changes in peroxide value and oxygen-containing compounds were monitored against time at high temperature, using iodometry and infrared spectroscopy (IR), in order to investigate the mechanism of oxidation of a hydrotreated lube base oil. The results of the tests indicate that the thermal oxidative mechanism conforms to the radical reaction theory, which is in the medium oxidative stage. The indirect analytical method of infrared spectroscopy is an effective method to study oxidative mechanisms. The content of carbonyl compounds and hydroxyl compounds decreased, and the content of hydroxyl compounds showed a slight increase at high temperature. No organic acids or esters were generated during the oxidative process.     

一种新的测井曲线环境校正方法——在平湖油气田中的应用

波阻抗反演是寻找隐蔽油气藏常采用的技术,但由于一些地区的钻井存在扩径现象,导致声波时差和密度曲线不能反映地层的真实情况,难于区分储层和围岩。为此,在进行反演之前必须对测井曲线进行环境校正,消除扩径对测井曲线带来的影响。以平湖油气田古近系渐新统花港组为例,在分析了该区扩径对测井曲线影响情况的基础上,提出了一套有效校正密度和声波时差曲线的方法:对测井资料进行标准化;应用未扩径处的标准化测井资料,建立自然伽马与密度的相关关系,并应用该关系结合压实校正对扩径处的密度曲线进行校正;应用Gardner公式,通过密度求取声波时差;在钙质发育处对上述校正的密度和声波时差进行钙质校正。应用效果表明,该方法是有效的。这给测井曲线环境校正提出了一个新的思路。     

A two-tower scheme for selective treatment of lube oil feedstock

The high efficiency of the two-tower scheme for treatment of I-20 and I-40 lube distillates with phenol and furfural and deasphalting product from mixed Baku waxy crude oils is demonstrated. In treatment with this scheme, it is possible to reduce consumption of furfural: by 2.4 times for I-20 lube oil distillate and by 2 times for I-40 lube oil and deasphalting product. A small increase in the yield of raffinates and dewaxed lube oils is also observed. During dewaxing, the rate of filtration of a cooled solution of raffinates obtained with the two-tower scheme is 1.53–1.7 times higher than for the one-tower scheme. For this reason, the number of vacuum filters in the unit can be decreased.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 1, pp. 22 – 24, January – February, 2005.
