致密油藏开发已成为全球非常规石油勘探开发的热点,我国致密油藏资源丰富,在松辽、鄂尔多斯、四川盆地等广泛分布,与传统石油能源相比,其开采难度大,成本高。随着油田勘探程度加深,其储量动用成都越来越高,开发技术的要求也越来越高。基于国内现状和美欧的技术发展趋势,加强对致密油藏岩石物理学基础研究,完善开发配套技术,促进非常规油藏最大限度地开发。 相似文献

油页岩地面干馏技术研究 总被引:2,自引:0,他引:2
近年来,随着国际石油供求矛盾的不断突出和石油价格的居高不下,油页岩资源逐渐引起了众多科研人员的青睐.油页岩是一种重要的非常规油气资源.世界油页岩分布范围广,储量十分丰富,其探明可采储量如果折算成页岩油,数倍于世界原油的探明储量.页岩油作为石油的一种理想替代品,进行油页岩制油技术的研究不仅蕴含巨大的商业利益和经济价值,对国家安全和能源战略也具有十分重要的意义.油页岩制取页岩油的技术可分为地面干馏技术和原位开采技术.地面干馏技术的工艺和设备发展比较成熟,也是目前制取页岩油最主要的途径.根据颗粒粒度的大小又可分为块状干馏技术和小颗粒干馏技术.着重介绍的块状油页岩干馏技术有抚顺炉技术、Kiviter技术和Petrosix技术,小颗粒干馏技术有Tosco-Ⅱ技术、ATP 工艺和Enefit-280工艺等.最后指出了油页岩地面干馏技术的发展趋势. 相似文献

油砂作为一种储量丰富的非常规石油资源,越来越受到世界各国的广泛关注。对于油砂的加工利用,其前提就是油砂沥青的分离,因此对其技术的研究十分必要。本文首先介绍了油砂的组成及分类,然后着重对几种主要油砂分离技术(热水洗法、有机溶剂萃取法、超临界流体萃取法、超声波辅助萃取法、离子液体萃取法和热解干馏法)的优缺点进行了汇总,并详细分析了它们各自的分离流程。其中,热水洗法、有机溶剂萃取法和热解干馏法是目前研究相对成熟的3种方法,而其他方法虽然分离效果相对高,但是对工艺条件和设备的要求较高,导致较高的投资和运行成本,因此还需要对这些油砂沥青分离工艺进行更加深入的研究,以满足工业化应用的要求。最后,对油砂沥青分离技术的发展前景进行了展望。 相似文献

This review provides a general overview of microwave applications in oil sands bitumen or shale oil production in petroleum upgrading. The vast oil reserves in the oil sands of Alberta will become a major source of petroleum products in the near future and a number of alternative technologies have been explored for the production and upgrading of oil sands and heavy oil. This study is based primarily on the unique selective heating capacity associated with exposure of materials to microwaves. Of particular interest are applications of microwaves for bitumen extraction, upgrading heavy oils, removing heteroatoms, and the underground heating of oil sands to reduce bitumen viscosity and allow it to be pumped to the surface. The fundamentally different method of transferring energy from the source to the sample is the main advantage of utilizing microwave energy. By directly delivering energy to microwave-absorbing materials, conventional issues such as long heating periods and energy loses can be minimized. Microwave energy was shown to be effective in some applications; however, it is not used commercially at the present time. 相似文献

Processibility curves have shown that strong inorganic bases or anionic surfactants are effective as process aids in the hot water extraction of bitumen from oil sand, but maximum bitumen recovery for each oil sand type is the same for both types of aid. Nonionic surfactants were not useful and there was no general relationship between recovery and surface tension or pH. Bitumen recovery could be correlated with the fine solids component of oil sand. The amount of NaOH required to reach maximum recovery and the rate of aging of oil sand were also functions of the fine solids content. Shear during slurrying was also found to be important, and it was shown that, without a certain amount of mechanical energy, good bitumen recovery could not be achieved, regardless of how much process aid was used. A theory of processibility is proposed to explain the interactions among process aids, mechanical energy, oil sand fines, and age of oil sand after mining. 相似文献
