چکیده

Abstract A new temperature-resistant and salt-tolerant mixed surfactant system (referred to as the SS system) for enhancing oil recovery at Tahe Oilfield (Xinjiang, China) was evaluated. Based on analysis of crude oil, formation water rock components in Oilfield, long-term thermal stability, salt tolerance ability change wettability, interfacial activity washing efficiency were studied. The contains anionic SDB another cationic SDY. When total mass concentration solution is 0.15 wt%, m(SDB)/m(SDY) ratio 1 1, excellent efficiencies are achieved five kinds oils (more than 60%). In addition, after adding surfactant, adsorption capacity further reduced, reaching 0.261 mg/g. displacement experiments indicate that under a temperature 150 °C salinity 24.6 × 10 4 mg/L, enhances by over 10% flooding. anionic–cationic first presented open literature can be successfully applied obtain predictions carbonate reservoirs with high salinity.

Network-based transcriptome analysis in salt tolerant and salt sensitive maize (Zea mays L.) genotypes

Identification of genes involved in salinity stress tolerance provides deeper insight into molecular mechanisms underlying salinity tolerance in maize. The present study was conducted in the faculty of agriculture of Urmia university, Iran, in 2018, with the aim of identifying genetic differences between two maize genotypes in tolerance to salinity stress, and the results of gene expression wer...

Salt-related Genes Expression Pattern in Salt-Tolerant and Salt-Sensitive Cultivars of Cotton (Gossypium sp.) under NaCl Stress

Salinity is one of the most important limitation factors in development of agricultural products. Cotton has a relative tolerance to salinity; however, salinity reduces its growth during germination and seedling stages. In this research, split-factorial design of time based on randomized complete block design with 3 replications was used. The real-time PCR results for, root, stem, and leaves of...
