Introduction Milankovitch theory has extensive application in sequence stratigraphy and the establishment of time scales. However, it is rarely applied to shallow strata rich hydrates. Cyclostratigraphic analysis Quaternary unconsolidated sediments can help identify climate sea level changes that correspond orbital cycles improve our understanding dynamic evolution Methods Using natural gamma-ray log data from deepwater area well W01 Qiongdongnan Basin, cycle was conducted primary...
The clinothem is the fundamental element of basin infill and plays an important role in source-to-sink system deep-water basins. In this study, which based on 2D 3D seismic data, spatiotemporal evolution clinothems depositional systems from Miocene to Pleistocene Qiongdongnan Basin, northern South China Sea, investigated. following conclusions are drawn: (1) three variations Basin were recognized respective O-, S- F-type clinothems; (2) fluctuations relative base level, combination with...
Abstract The Earth has witnessed the emergence of continental-sized ice sheets, starting with Antarctica and gradually extending to both hemispheres over past 40 million years. These accumulations have had a dramatic impact on paleoclimate sea level, substantially influencing sediment deposition in continental margins. However, understanding accumulation an orbital scale margins remains limited because scarcity high-resolution, chronologically constrained sedimentary records. Here, we...
Investigating the impacts of rock composition on pore structure is great significance to understand shale gas occurrence and accumulation mechanism. Shale samples from over-mature Niutitang formation Lower Cambrian in south China were measured by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), low pressure N2 CO2 adsorption elucidate controls distinct mineral development. Two lithofacies, namely siliceous argillaceous shale, ascertained based their composition....
Unconformities are of significant interest to petroleum geologists because their crucial roles in influencing reservoir quality and controlling oil gas migration. This study investigates the impact unconformities on a within prolific oil–gas-bearing zone between Middle Permian Lower Triassic strata northwestern Junggar Basin, utilizing thin sections, well logging data, seismic profiles, geochemical analyses. The results reveal well-developed three-layer unconformity structure characterized...
Abstract The lower Cambrian Niutitang shales, as one of target intervals with the greatest potential for shale gas exploration and development, have attracted much attention. Nevertheless, organic matter enrichment mechanisms shales need further study, especially in hydrothermal active zone. In this samples from ND1 well western Hubei Province, middle Yangtze region, South China, were investigated controlling factors accumulation Lower by detailed petrographic, mineralogic, geochemical...
