Based on the exploration and development practice of marine shale gas in Fuling, Weiyuan, Changning, Luzhou Southeast Chongqing southern China, combined with experiments analysis, six factors controlling differential enrichment are summarized as follows: (1) The more appropriate thermal evolution higher abundance organic matter, adsorption total content will be. (2) Kerogen pyrolysis liquid hydrocarbon cracking provide most gas. (3) specific surface area pore volume matter rich increased...
Shale gas exploration and development is regarded as one of the vital areas in which breakthroughs are urgently needed. The Longmaxi Formation shale Weiyuan Block was considered a case study. Based on analysis physical evolution, burial history, thermal well hydrocarbon generation history shales, impact uplift amplitude reservoirs, transport pattern direction adjustment stage, enrichment discussed this results from study showed that (1) could reach maximum depth Late Middle Cretaceous, then...
Abstract Land snails exhibit the potential for capturing synoptic‐scale precipitation events through δ 18 O records of their shells (δ shell ), but application is hindered by absence a practical methodology tracking these events. Here, we developed statistical to track from daily resolved snail body fluid BF ) record. We further tested and verified our approach using modern Cathaica fasciola Chinese Loess Plateau (CLP). The reconstructed 3‐day‐timescale frequencies first derivations shows...
Shale gas has become one of the most important natural resources. The Sichuan Basin in China is main shale production areas and entered large-scale commercial development. mechanism accumulation an scientific problem exploration. This work systematically summarizes understanding terms generation mechanisms, pore evolution migration models. reviews formation process methane clarifies that causes vary according to evolutionary stage. organic pores mineral are analyzed using a thermal...
Abstract To reveal the effect of shale reservoir characteristics on movability oil and its action mechanism in lower third member Shahejie Formation (E s 3 l ), samples with different features were selected analyzed using N 2 adsorption, high‐pressure mercury injection capillary pressure (MICP), nuclear magnetic resonance (NMR), high‐speed centrifugation, displacement image techniques. The results show that pore structure control directly. Movable saturation has a positive relationship...
To figure out porosity evolution mechanisms of marine shales inside and at the margin Sichuan Basin, South China, we measured samples selected from Lower Cambrian Qiongzhusi Silurian Longmaxi by a combination X-ray diffraction, geochemistry measurement, focused ion beam milling scanning electron microscopy imaging, [Formula: see text] adsorption. It was suggested that upper Formation (a shallow continental-shelf setting) abyssal possessed larger pore volumes surface areas than those lower...
The entire process of shale gas generation, migration, and accumulation involves the diffusion gas, it is impossible to disregard harm that does reservoirs. research object for this paper Longmaxi Formation reservoir in Weiyuan area Sichuan Basin. Based on Fick’s law, an innovative mathematical model established, clarified amount mainly depends free content coefficient. theory fluid dynamics, calculation equation formation paleo-pressure innovatively deduced. fully considers temperature...

Aero-engine maintenance mode was transferred from the prescheduled to condition-based maintenance. The can help improve engine reliability and reduce costs. study of condition monitoring system key step According characteristics aero-engine high speed signal, this paper designs system. Firstly, foreign experience learned. structure, functional requirements selection events were proposed for a system, then principle prototype its simulation platform airborne implemented, which helpful study.
