塔里木油田水碳酸盐平衡系数与有机酸的意义

根据统计学规律,对塔里木盆地油田水进行了研究,阐明了该盆地油田水的碳酸盐平衡系数(简称为R_C)与有机酸的基本特征。从油田水的无机组分与有机组分的统计分析中发现了油田水的碳酸盐平衡系数与有机酸存在明显的负相关性,进一步论证了碳酸盐平衡系数和有机酸与油气聚集及油气性质的关系。碳酸盐平衡系数越低及低碳有机酸的含量越高,它们与油藏,尤其是与 轻质油或气藏的关系越密切。从两者的关系中初步了解到有机酸的溶蚀作用对油气藏中储层次生孔隙的形成应有较重要的影响。

Design Methodology and Area Sensitivity Analysis of Horizontal Subsurface Flow Constructed Wetlands

An approach is presented to satisfy the demand for simple criteria, guidelines and models for the preliminary sizing of horizontal subsurface flow (SF) constructed wetland systems. This approach eliminates time-consuming calculations and iterations by providing graphical solutions for wetland system sizing. Therefore, it can be used for the preliminary assessment of new or performance evaluation of existing subsurface flow constructed wetland systems. The validity of this methodology is checked with data from existing systems and is found to be quite satisfactory. This methodology is combined with simple equations predicting the maximum wetland capacity in summer, so as to assist designers in sizing installations in tourist areas with increased summer populations. Furthermore, based on this methodology, a sensitivity analysis is performed of the area requirements for wastewaters of various strengths and various design conditions and performance criteria. The results provide a useful overview to engineers and further simplify the design methodology of new subsurface flow constructed wetland systems.     

N-油酰基肌氨酸钠对除盐水缓蚀性能的探讨

对N-油酰基肌氨酸钠单体的缓蚀性能以及与常用除盐水缓蚀剂的协同作用作了探讨,发现在一定浓度下,单体对经过加氨调节后的高温除盐水(氨后除盐水)有良好的缓蚀作用,且与大多数除盐水缓蚀剂有良好的协同效应。在此基础上研制了一种复合药剂,并对其缓蚀、阻蚀性能作了研究。动电位极化曲线扫描图谱表明,该复合药剂属于抑制阳极腐蚀的阳极型缓蚀剂,其适用的水质条件为[Cl~-+SO_4~(2-)]不超过50 mg／L,pH不低于8.0；与阻垢剂复配,可以适用于含Ca~(2+)不超过45 mg／L的水质条件。     

高压变频技术在油田注水系统中的应用与节能分析

油田注水系统的耗电量一般占整个油田生产耗电的40％-60％,因此降低注水系统的能耗可显著降低油田的生产成本。常规的通过调节阀门开启度来达到调节注水泵出口压力和流量的作法,会使很大一部分能量造成浪费,要解决这个问题,可以采取对注水泵进行调速的方法。文章论述了通过高压变频技术对注水泵进行调速,从而达到节能效果的基本原理;对一台恒速泵和一台变频调速泵并联运行时的效率进行了分析,并对应用实例进行了计算,注水站的效率比原来提高了9．04％,收到了显著的节能效果。     

Synthesis and photosensitivity of acryloylmorpholine copolymers with a pendant (meth)acryloyl group

We have developed new photopolymers that have superior waterproof properties and that can easily interact with polyfunctional acrylate compounds, thus serving as hydrophobic photocrosslinking reagents. Acryloylmorpholine monomers whose homopolymers were less moisture absorbing than the usual water‐soluble polymers but were still water soluble to a good degree, were copolymerized with other acryloyl monomers. We then introduced the photosensitive (meth)acryloyl group to side chains of the resulting polymers. Among six copolymers examined, the copolymers composed of acryloyl morpholine, hydroxyethyl acrylate, ethyl, or methyl methacrylate, and methacryloyl isocyanate were found to have nicely balanced hydrophilicity and waterproof properties, in addition to good compatibility with hydrophobic photocrosslinking reagents. The composite polymers thus obtained were confirmed to be promising photopolymers usable even in a highly humid environment. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 87: 684–692, 2003
