Abstract Alkali–surfactant–polymer (ASP) flooding is a chemical enhanced oil recovery method; its working mechanisms include mobility control, wettability alteration, and in‐situ emulsification. However, conventional alkalis used in the ASP could cause some serious issues, including scaling, formation damage, pipe corrosion. In this study, we investigated feasibility of incorporating organic as additives hot water to enhance heavy recovery. The focus was on studying interfacial properties,...
Summary The effects of chemical additives on mitigating water blocking and improving oil recovery were experimentally examined for gas-water oil-water systems in spontaneous imbibition cells. In these attempts, two factors are critically important: (1) understanding the physics interaction, whether it is co- or countercurrent, (2) characteristics to suitably orient interaction specific purposes (accelerate/decelerate matrix-fracture interactions). Co- countercurrent experiments conducted...
We evaluated the influence of boundary conditions on matrix-fracture interaction dynamics and compared effectiveness various chemical agents under different reservoir environments. Chemical selection was investigated for applications, i.e., hydraulic fracturing in gas oil reservoirs enhanced recovery (EOR) latter. Results showed significant differences performance chemicals when they were applied carbonate sandstone cores. Notably, cationic surfactant CTAB, which unsuitable EOR cores,...
Abstract Matrix-fracture fluid interactions occur during both the fracturing and recovery stages in naturally hydraulically fractured oil gas reservoirs. Understanding physics mechanisms of these (co- or counter-current manners) is vital for selecting proper chemicals as EOR additives. While traditional core experiments often treat a black box, microscopic visualization offers direct observations key phenomena such interfacial instability, wettability alteration, emulsification, particularly...
To carry out a nationwide epidemiologic survey on the neonates in urban hospitals with an attempt to understand disease spectrum and treatment outcomes of hospitalized China.The clinical data 43,289 from 86 47 Chinese cities (22 provinces) between January 1, 2005 December 31, were retrospectively analyzed.The male:female ratio was 1.73:1. Premature infants accounted for 26.2% neonates, which higher than that reported 2002 (19.7%). The top three diseases during neonatal period jaundice,...
Objective Low-cost diagnostic and prognostic biomarkers could help guide clinical management of neonates with myocardial injury after asphyxia. This study aimed to assess the utility creatine kinase (CK)-MB, high-sensitivity cardiac troponin I (hs-cTnI), brain natriuretic peptide (BNP), myoglobin in early diagnosis following neonatal Methods Eighteen asphyxia injury, 22 no 19 without (controls) were enrolled consecutively at Neonatology Department, First Hospital Lanzhou University (August...
Heparin-modified graphene oxide was prepared as the carrier of anti-cancer drugs and growth factor with long-term release property, reduced cytotoxicity improved heat stability.
Abstract Solvent-based enhanced heavy oil recovery techniques are promising alternatives to thermal-based methods. A better understanding of the solvent-diluted gravity drainage is important practical field-scale applications solvent-based processes. In particular, transmissibility, which defined as product absolute permeability k and pay-zone thickness h an reservoir, parameter affect drainage. this paper, a series experimental tests were conducted in visual high-pressure physical model...

Binocular tone mapping aims to improve the overall quality of image erceived by human eye, and has been continuously optimized since it was proposed. Based on visual perception experiment, a series experiments are designed for binocular ability eyes. On this basis, based non‐reference algorithm is The more streamlined closer framework, adaptive in practice.
Objective To analyse the pathway of infection,risk factors,clinical characteristics and pathogenic bacteria distribution neonatal sepsis.Methods Eighty-eight with sepsis were enrooled from January 2006 to December 2011 in First Affiliated Hospital Lanzhou University.According disease stage,they divided into early-onset group late-onset groups.Results Respiratory infections two groups was majority (44.7％ vs.46.0％),and there no significant difference (P =0.906).That premature birth,low birth...
Abstract Due to the confinement and strong adsorption pore wall in meso- nano- pores, fluid phase behavior confined media, such as tight shale reservoirs, can be significantly different from that bulk phase. A large amount of work has been done on theoretical modeling hydrocarbons media. However, there are still inconsistencies models developed validations those against experimental data inadequate. In this study, we conducted a comprehensive review under analyzed various phase-behavior...
