Experimental study of the influencing factors and mechanisms of the pressure-reduction and augmented injection effect by nanoparticles in ultra-low permeability reservoirs

Petroleum Science 2024年第3期21卷 1915-1927页

Nanoparticles(NPs) have gained significant attention as a functional material due to their ability to effectively enhance pressure reduction in injection processes in ultra-low permeability reservoirs. NPs are typically studied in controlled laboratory conditions, and their behavior in real-world, complex environments such as ultra-low permeability reservoirs, is not well understood due to the limited scope of their applications. This study investigates the efficacy and underlying mechanisms of NPs in decreasing injection pressure under various injection conditions(25—85°C, 10—25 MPa). The results reveal that under optimal injection conditions, NPs effectively reduce injection pressure by a maximum of 22.77% in core experiment. The pressure reduction rate is found to be positively correlated with oil saturation and permeability, and negatively correlated with temperature and salinity. Furthermore, particle image velocimetry(PIV) experiments(25°C, atmospheric pressure) indicate that the pressure reduction is achieved by NPs through the reduction of wall shear resistance and wettability change. This work has important implications for the design of water injection strategies in ultra-low permeability reservoirs.

Realizing high-rate capability and high-efficiency utilization of polyanionic cathode materials is of great importance for practical sodium-ion batteries(SIBs) since they usually suffer from extremely low electronic conductivity and limited ionic diffusion kinetics. Herein, taking Na_(3.5)V_(1.5)Mn_(0.5)(PO_(4))_(3)(NVMP) as an example, a reinforced concrete-like hierarchical and porous hybrid(NVMP@C@3DPG) built from 3D graphene(“rebar”) frameworks and in situ generated carbon coated NVMP(“concrete”) has been developed by a facile polymer assisted self-assembly and subsequent solid-state method. Such hybrids deliver superior rate capability(73.9 m Ah/g up to 20 C) and excellent cycling stability in a wide temperature range with a high specific capacity of 88.4 m Ah/g after 5000 cycles at 15 C at room temperature, and a high capacity retention of 97.1% after 500 cycles at 1 C(-20 ℃), and maintaining a high reversible capacity of 110.3 m Ah/g in full cell. This work offers a facile and efficient strategy to develop advanced polyanionic cathodes with high-efficiency utilization and 3D electron/ion transport systems.

马克思伦理思想揭示道德的本质是社会经济关系表现的意识形态,正确理解的利益是道德的基本原则,自由、人类共同体和自我实现是道德实现的基础。从整体上看,马克思伦理思想形成了从抽象的自然人到现实的社会人、从道德批判到道德建构、从价值理性到科学理性、从个体主义到制度主义的发展逻辑,为我们提供了历史唯物主义的理论导向和思维方法,有助于跳出西方自由主义和共同主义的伦理纷争以及避免我国历史上平均主义伦理的非理性。夯实共同富裕的伦理基础,应明确人的全面发展的价值目标,坚定人民利益至上的价值立场;推动经济社会高质量发展,培育和营造积极健康的财富观;遵循市场经济发展规律,把握共同富裕不同阶段的动态伦理;以法治护航社会公平正义,完善分配制度和诚信制度。
