随着社会经济的发展,常规的油气资源在不断枯竭,常规油气资源已经满足不了经济快速发展,因此石油勘探开发的方向逐渐转向非常规油气资源。文章通过文献调研和理论分析,研究分析了煤层气、页岩气、油砂、油页岩等非常规油气资源在我国分布和勘探开发现状,重点分析了新疆准噶尔盆地非常规油气资源类型和开发现状,提出了提高准噶尔盆地非常规油气资源勘探开发政策和建议。非常规油气资源是对我国常规油气资源的补充,对于我国的能源的可持续发展具有重要的意义。 相似文献

非常规油气资源是指在成藏机理、赋存状态、分布规律以及勘探开发方式等方面有别于常规油气藏的油气资源。现在非常规油气资源的开发利用日益受到世界各国的重视,且已成为常规油气资源的战略性补充,但是非常规油气资源评价与常规油气资源评价方法有较大的差异,不能直接套用。基于非常规油气聚集的成藏机制和分布特征,本文详细介绍了国内外几种非常规油气资源的评价方法,并结合我国非常规油气资源的特点,对非常规油气资源评价提供了方法建议。 相似文献

非常规油气理论是在常规油气理论上的一次质的飞跃,非常规油气在中国经过了10年的发展,已经有自己基本的框架和结构理论了。所谓的非常规就是不能用常规技术开采的石油与天然气。非常规油气地质学目前整个体系还不够成熟,我们要积极的建立和完善这门有巨大潜力的学科,非常规油气其发展潜力十分巨大,但目前为止非常规油气地质学科在油气资源综合利用、能源结构科学预测、复杂问题创新解决等方面仍有发展空间。本文就非常规地质学的背景、非常规油气地质学的概念、非常规油气成藏地质学以及非常规油气地质学在实际生产中的应用做了论述,希望对今后的非常规油气地质学的发展提供一定的帮助。 相似文献

Synthesis and characterization of homopolymers and copolymers of various acrylates and acrylonitrile
Various homopolymers and copolymers of methyl acrylate, ethyl acrylate, butyl acrylate, and acrylonitrile in different feed ratios were synthesized. These were characterized by IR, 13C-NMR, DSC, DTA, and TGA. Spectroscopic characterization helped in differentiating copolymers of different mol ratios. Thermal analysis revealed different degradation patterns for homopolymers and copolymers. The temperature and energy changes associated with various phase transitions were dependent on the chemical composition of homo- and copolymers, as expected. © 1993 John Wiley & Sons, Inc. 相似文献

The variation of the Au 4f binding energy of Au clusters with the cluster size has been established by measuring the binding energies of clusters whose size distributions were independently determined by HREM and STM. The binding energy increases significantly when the cluster size is less than 2 nm. Au-Cu bimetallic clusters of the composition Cu3Au have been deposited for the first time on carbon substrates. The shifts in the core level binding energies of the bimetallic clusters show the effect of alloying in the case of large clusters, but show effects of both alloying and cluster size in the case of the small clusters. The interaction of CO with Cu3Au clusters is stronger than with a bulk Cu metal. The interaction of CO with small Cu clusters also seems to be stronger than with bulk Cu or with large Cu clusters. 相似文献

Abstract Kinetics and mechanisms of oxidation of 6 acetals by molecular oxygen and ozone in liquid phase have been studied. Reaction with molecular oxygen (70°C, 15–16 hr) leads to the formation monoethers of the corresponding glycols with 68–90% selectivity. Salts of metals and complexes with crown-ethers have increased the reaction rate significally. Ozone have reacted with acetals with formation similar products. The mechanisms of intermediate stages have been proposed. 相似文献

A substantially greater detachment energy is required to strip a polyethylene tereph-thalate (Mylar) film from a styrene-butadiene-styrene (SBS) triblock copolymer compared to that for peeling from a random styrene-butadiene (SBR) copolymer. This is true even though the intrinsic interaction between the Mylar and each elastomer is expected to be similar because of their virtually identical chemical composition. It is proposed that this difference in peel strength (between the SBS and SBR) is a consequence of the much higher dissipative capacity of the former elastomer. Another manifestation of this is the higher cohesive tear strength of the SBS compared to the SBR. Extents of energy dissipation within each elastomer during detachment of the Mylar adherend are consistent with the hypothesis that the average maximum stress experience before detachment is some similar fraction of each elastomer's tensile strength. 相似文献

责任是人应主动承担的角色义务和对其因过失所造成后果应承担的责罚.有两层涵义:一是义务;二是后果.责任心是个体自觉做好分内事务和履行道德义务的心理倾向,是个性心理品质成分中自我特征维度上的重要内容.责任心具有两个方面的涵义:一是角色分内职责;二是角色道德义务.责任心是一种通过责任认知、责任个性和责任适应的动态形式表现出来的静态品质,责任心是责任心过程结构与责任心关系结构相互制约、相互影响的统一体. 相似文献

Polypentafluorostyrene (PPFS), polymethylacrylate (PMA), and poly(pentafluorostyrene-co-methylacrylate), poly(PFS-co-MA) were prepared and the wetting characteristics of polymer blends of PPFS and PMA were compared with that of poly(PFS-co-MA) via contact angle measurements. The critical surface tension of polypentafluorostyrene was found to be 22.6 dyne/cm, which is comparable to the value reported for polytrifluoroethylene (22 dyne/cm). The critical surface tension of poly(PFS-co-MA) is not linearly related to its composition. The polymer blends of PPFS and PMA exhibit significant surface enrichment of the fluoropolymer. The harmonic-mean method1 was employed to determine surface tensions of these polymers and many known polymers. It is found that the method produces useful surface tension data provided the contact angle values are derived from testing liquids of dissimilar polarity. 相似文献
