The water adsorption by shale significantly affects gas content and its seepage capacity. However, the mechanism of is still unclear due to strong heterogeneity complicated pore structure. relationship between adsorbed at different relative humidities (RHs) compositions, as well structure spatial configuration organic matter (OM) clay minerals, was investigated clarify controlling factors mechanisms Longmaxi Formation from Southern Sichuan Basin in China. Consequently, process could be...
The annual output of shale gas from the Wufeng-Longmaxi formations in South China reached 15.4 × 109 m3 2019, which makes Sichuan basin second-largest producing area world. Based on data more than 1000 samples taken typical drilling and outcrop profiles Weiyuan, Changning, Fuling, Wuxi areas China, characteristics differential enrichment are analyzed main controlling factors discussed. study shows that has some both vertical lateral orientations. In orientation, sweet-spot intervals...
Strong overpressure conditions are widely distributed in the deep Longmaxi Formation (Fm) shale reservoirs Southern Sichuan Basin, with pressure coefficients ranging from 1.75 to 2.45. Overpressure plays a positive role high yield of gas, but detailed study its generation mechanism, evolution history, and potential impact on pore development is still lacking. This study’s evidence theoretical analysis logging response method indicates that hydrocarbon expansion main mechanism for strong...
The organic-rich shale of the Permian Taiyuan Formation (TYF) and Shanxi (SXF) in Southern North China Basin (SNCB) is considered a potential gas source. was formed marine-continental transitional sedimentary environment, which has rarely been studied, with enrichment mechanisms organic matter (OM) remaining unclear. This study investigated controlling factors OM by analyzing total carbon (TOC) content, paleoclimate, paleoproductivity, sedimentation rate, redox, paleosalinity. TOC TYF ranged...
Throughout the recent decade, drone delivery technology has been developed to address problems such as last-mile and recurrent traffic jams in metropolitan regions. To resolve relatively short travel range limited capacity issues of drones, researchers have proposed further enhance utility drones by deploying them with ground vehicles (e.g., trucks) tandem. This new concept leads a transportation planning problem, i.e., coordinated trucks (CDTD). In this paper, we conduct comparative study...
Abstract Granular activated carbon (GAC) has been used to remove organics and metals simultaneously from wastewaters (4). For a regeneration procedure be effective on GAC containing both organics, it must the organic compounds. In this study, saturated with Pb phenol was regenerated using an NaOH rinse in batch mode. Four variables were investigated: 1) regenerant concentration (0, 0.1, 1.0 N), 2) mass ratio (5:1 10:1), 3) temperature (22 80°C), 4) time (0.33, 1, 3, 7, 21 days). Maximum...
Carbon-covered alumina (CCA) has been reported to be a promising catalyst support or adsorbent. In the literatures, most of CCAs were prepared by pyrolysis gaseous hydrocarbon on surface, which was usually not uniformly covered carbon. this paper, simple and novel process developed for preparation uniform carbon-covered via sucrose highly dispersed surface alumina. addition, coverage number carbon layers in CCA can easily controlled changing content precursors impregnation times.
An algorithm for image analysis that based on variogram function was proposed in this paper. Variogram can take randomicity of the region variation and structure spatial distribution into account. Image data are not pure random variable, they obviously have features, so we put a regional variable. We use value single step to describe statistical characters adjacent points image, different texture should function, therefore paper it as main feature segmentation. The method has merit direction...
The pore structure characterization and its controlling factors in overmature shales are keys to understand the shale gas accumulation mechanism. Organic matter source rocks is a mixture of various macerals that have their own specific evolutionary pathways during thermal maturation. Pores within also evolve following path. This study focused on petrographic maceral controls porosity marine China United States. Shale from Ordos Basin was selected as an example transitional for comparison....
Various studies have shown that geo-catalytically mediated methanogenesis could happen in immature to early-mature source rocks at temperatures ranging from 60 140°C based on a series of long-term laboratory heating experimental evidences. The results those show methane yields the given temperature are 5–11 orders magnitude higher than theoretically predicted early thermogenic generation kinetic models. However, different types these simulation experiments generated varied CH 4 and CO 2...
In the deep Longmaxi Formation shale gas reservoirs of southern Sichuan Basin, strong overpressure is universally developed to varying degrees. However, there currently a lack in-depth research on formation mechanisms, evolutionary patterns, and controlling effects reservoir pore characteristics overpressure. This limitation significantly restricts evaluation reservoirs. study selected typical overpressured wells in Yongchuan, Luzhou, Dazu areas as subjects. Through comprehensive methods...
Early-warning signals of delicate design are always used to predict critical transitions in complex systems, which makes it possible render the systems far away from catastrophic state by introducing timely interventions. Traditional including dynamical network biomarker (DNB), based on statistical properties such as variance and autocorrelation nodal dynamics, overlook directional interactions thus have limitations capturing underlying mechanisms simultaneously sustaining robustness against...
The Boussinesq approximation, where the viscosity depends polynomially on shear rate, finds more and frequent use in geological practice. In this article, we consider periodic initial value problem for non-Newtonian equations describing behavior of flows an incompressable viscous fluid processes thermal effects play essential role. existence weak solution is proved p ≥2, its uniqueness regularity p>(1+2n/(n+2)).
