Dolomite reservoirs formed by dissolution are significant for hydrocarbon exploration, but their origins poorly understood because of complexity. This study investigated the lower Permian Qixia Formation Sichuan Basin (northern Longmenshan Mountains), southwestern China, which has recently been location giant natural gas discoveries. Petrological and geochemical analyses were undertaken, including trace elements C, O, Sr isotopes. The results indicate that differential eogenetic...
Rhizoctonia solani causes the disease peanut sheath blight, involving symptoms of maceration and necrosis infected tissue, mainly caused by cell-wall-degrading enzymes (CWDEs). This study investigated production CWDEs including polygalacturonase (PG), polymethyl-galacturonase (PMG), cellulase (Cx) β-glucosidase R. in vitro (in liquid culture) vivo plants). Significant PG, PMG, Cx activities were detected tissues stalk leaves Baisha Silihong cultivars. Extracts healthy tissue showed little or...
Based on the outcrops, drilling cores, thin sections observation and geochemical analysis, studies were done genesis of dolomite in Middle Permian central Sichuan Basin. Mosaic fine-crystalline subhedral-euhedral siliceous can be identified microscopically, which have different characteristics. Genetic analysis indicates insufficient mantle-derived fluids marine-derived entered karst system through basement faults, then mixed with previously-preserved crust-derived varied degrees during...
Due to the present tectonic and stratigraphic distribution characteristics in northwest margin of Sichuan Basin are complex, which restricts understanding sequence lithofacies paleogeography Middle Permian Maokou Formation. To investigate process tectonic–sedimentary evolution, basin-margin outcrop intra-basin well seismic data were used. The results show two structural sequences, namely, SSQ1 SSQ2, five third-order SQ1–SQ5, SSQ1, with stable formation thickness, shows a slow...
The potential for oil and gas exploration within inter-salt reservoirs is substantial, primarily due to their significant heterogeneity, which complicates accurate predictions. This study focuses on the of sixth sub-member fifth member Majiagou Formation (hereafter referred as O2m56) in Ordos Basin, North China. Utilizing core samples, thin sections, petrophysical data, we investigated differential evolution primary controlling factors carbonate reservoirs. key findings are follows: (1)...
The characteristics, formation time, and origin of the sucrosic dolomite reservoirs in Permian Qixia Formation northwestern Sichuan Basin are analyzed. Core outcrop description microscopic analysis samples carried out. It is found that has typical features different from other kinds dolomites: (1) This generally medium-coarse crystal size, often associated with very finely to crystalline cave-filling dolomite. (2) Typical identification marks eogenetic karstification developed at top...
Abstract The Emeishan large igneous province (ELIP) was a major geological event that took place around the Middle–Late Permian boundary. episode of ELIP is generally considered to have occurred at 260–259 Ma, although an increasing number data suggested multiple episodes magmatic activity might occurred. Here we report study Lower dolomite whose formation influenced by in Sichuan Basin southwestern China. Results show two new pulsed activities 273.2 ± 9.7 Ma 269.1 12.0 (ELIP-I) and 263.2...
Through the analysis of logging, field outcrops, cores and geochemical data, based on study relationships between sea level changes, sequence filling, paleo-geomorphy lithofacies, lithofacies paleo-geography evolution process Lower Permian Liangshan-Qixia Formation (Qixia Stage for short) in Sichuan Basin its surrounding areas are restored. The Qixia can be divided into three third-order sequences, which SQ0, SQ1 SQ2 developed depression area, only other areas. reflected by thickness each...
The dolomites of the Middle Permian Qixia Formation have been important targets natural gas exploration in Sichuan Basin for decades. However, more and research indicate that formation reservoir might be related to karstification. To testify this hypothesis, we conduct comprehensive outcrop, core, logging analyses based on a case study representative northwestern Basin, which has obtained breakthroughs recently. Results show dolomite reservoirs are mainly developed within fine-crystalline...
Penecontemporaneous dissolution has been considered as the dominant origin of reservoir formation, whereas epigenetic also played certain roles in improvement capacity Upper Cretaceous Mishrif Formation Middle East. Here, we report a possible new based on case study Halfaya oilfield Iraq, that is, facies‐controlled eogenetic karstification. The most representative evidence is early selective not only present relative high‐energy categories rocks but low‐energy ones cored intervals....
Acinetobacter baumannii is one of the main causes nosocomial infections. Increasing numbers multidrug-resistant cases have been reported in recent years, but its antibiotic resistance mechanism remains unclear. We studied 9 (MDR) and 10 drug-susceptible clinical isolates using Label free, TMT labeling approach glycoproteomics analysis to identify proteins related drug resistance. Our results showed that 164 exhibited different expressions between MDR isolates. These differential can be...
Based on the analysis of deposition and tectonism, "residual thickness method" is used to restore paleokarst landform Middle Permian Maokou Formation in northwestern Sichuan Basin. With feature plain with karst hilllock, this area can be classified into three secondary geomorphic units: platform, slope groove, which hillocks monadnocks platform are favorable zones for development reservoirs, exploration next step. Furthermore, grooves, often denuded Members Mao 3 or 2, seismic profiles show...
Based on analysis of outcrop, drilling, logging and seismic data, geotectonic background, the lithofacies paleogeography paleokarst geomorphology Middle Permian Maokou Formation in northwestern Sichuan Basin were reconstructed, petroleum geological significance discussed. The is divided into 3 long-term cycles, namely LSC1, LSC2 LSC3, which correspond to Member 1, 2 Formation, respectively. Controlled by extensional structure caused opening Mianlue Ocean north margin upper Yangtze blocks...
