this study aims to identify favorable oil–gas reservoir facies in the chishan group of the wubao fault zone (gaoyou sag, subei basin, china) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. the results suggest that the chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...

VLDLR gene was chosen as a candidate gene infl uencing abdominal fat trait and body weight due to previous studies in human and mouse. Herein, the objectives of this study were to identify genetic polymorphisms of duck VLDLR gene, and to analyze association between combined haplotypes and abdominal fat trait in Gaoyou domestic duck. A total of 207 individuals, including the elite reservation fa...

Water channel proteins, aquaporins, play fundamental roles in transmembrane water movements in plants. A new full-length cDNA encoding aquaporin was isolated from the seedlings of Jatropha curcas. The gene of the plasma membrane intrinsic protein (PIP) from J. curcas (JcPIP2) contained an 843 bp open reading frame encoding a protein of 280 amino acids. The amino acid sequence showed 94% identit...

The success of shale oil exploration and production is highly dependent on the heterogeneous nature reservoir pore structure. Despite this, there remains limited research heterogeneity characteristics pores at different scales in lacustrine reservoirs factors that impact them. This study aims to quantitatively characterize multi-scale differences found Funing Formation Gaoyou Sag. Additionally,...

In order to identify the degree of water flooding in a reservoir and discover any remaining oil-enriched areas, this paper, systematic study on cores obturated coring wells is carried out. With observations testing data cores, based notion sedimentary facies, water-flooding degrees 4–7 sand groups member one Paleogene Sanduo Formation (E2s14–7) Zhenwu area Gaoyou Sag are determined. Overall, re...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....

Serious power quality issues and huge economic loss can be caused by voltage sag. It’s helpful for grid corporation to estimate voltage sag loss. Voltage sag and influence of sensitive equipment are analyzed in the paper. An estimation method of voltage sag loss based on blind number theory is proposed, which takes the sag magnitude and duration as its main characteristic parameters. First Eucl...
