Compressive graphene aerogels were obtained by the one-step reduction and self-assembly of oxide with ethylenediamine then freeze-drying. The hold good compressibility, variable electrical resistance fire-resistance. high porosity a hydrophobic nature, allows to absorb different organic liquids, absorption–squeezing process has been demonstrated for oil collection.
The fracture network generated by hydraulic fracturing in unconventional shale reservoirs contains numerous microfractures that are connected to macroscopic fractures. These serve as crucial pathways for gas flow out from micro- and nano-scale pores, playing a critical role enhancing recovery. Currently, more attention is being given academia industry the evolution of networks, while understanding microfracture mechanisms relatively limited. A significant number during process shale....
For predicting the distribution of favorable reservoir facies belts super-large ancient Anyue carbonate gas field in Sichuan Basin, through an analysis structure and lithofacies paleogeography, paleogeography sedimentary model Sinian Dengying Fm was reconstructed based on outcrop, drilling seismic data. As a result, achievements are made four aspects. First, basin its periphery resided extensional tectonic setting Sinian. Intense extension led to formation Deyang–Anyue intra-platform rift....
Abstract The Jaz Murian Basin in Southeast Iran is a forearc basin that sits on top of the western Makran subduction zone. A recent seismic deployment inside documents extremely strong reverberations between free surface and basement. These multiples, which hamper studies deeper structures, carry precious information structure basin. Here we combine three independent measurements, including teleseismic P/S‐wave coda autocorrelations, P‐wave polarization analysis receiver functions, to image...
Mesozoic marine shale oil was found in the Qiangtang Basin by a large number of hydrocarbon geological surveys and shallow drilling sampling. Based on systematic observation experimental analysis outcrop core samples, deposition development conditions characteristics are revealed, geochemical reservoir evaluated, layers determined. The following understandings obtained. First, there two sets organic-rich shales, Lower Jurassic Quse Formation Upper Triassic Bagong Formation, Basin. They...
Trying to reveal the mechanism of gas seepage in coal is significance both safe mining and methane exploitation. A series FEM numerical models were built up studied so as explore mesoscale fractures. The proposed model a cube with micron fractures along three orthogonal directions. distribution velocity pressure under fluid-solid coupling was obtained, furthermore, flow flux an equivalent permeability whole calculated. influences fracture width, outlet velocity, situ stress level on...
In order to ensure the safety of Beijing–Shanghai high-speed railway during construction and operation shield tunnel on Line R1 Jinan Metro, a numerical simulation geological disturbance underpass small-radius stacked was carried out. We analyzed mechanism deformation factors affecting settlement found that bridge far exceeded standards without taking control measures. this regard, technologies such as setting isolation pile sleeve valve pipes, controlling tunneling parameters, grouting...
In this paper, the robust non-fragile stabilisation and H ∞ control problem is investigated for a class of uncertain discrete-time stochastic systems with Markovian jumping parameters time-varying delay. The parameter uncertainties are supposed to be as well norm-bounded. aim design state feedback controller which guarantees stability closed-loop system all admissible uncertainties. At same time, in addition requirement, prescribed performance level required achieved problem. By Lyapunov...
A breakthrough was made in tight marlstone reservoirs from an evaporative lagoon the second sub-member of third member Leikoupo Formation (Lei3-2) Central Sichuan Basin. The source rock characteristics, reservoir characteristics and geochemical parameters oil natural gas were investigated to evaluate unconventional hydrocarbon exploration potential lagoon. results revealed that rocks deposited environments, average total organic carbon (TOC) content value for samples 0.75 wt%. thermal...
In recent years, new breakthroughs have been made in the field of shale oil and gas exploration Lower Jurassic Lianggaoshan Formation Sichuan Basin. At present, there is a lack systematic studies on reservoir properties sedimentary facies shale. Therefore, this study, taking Basin as an example, types reservoirs their control over are systematically studied, based large number outcrops, experimental testing, logging, seismic interpretation methods. The results show that five microfacies...
Abstract The relationship between the North and South China blocks, particularly their spatial-temporal framework evolutionary history, has been widely debated. We conducted a comprehensive study of structural geometry kinematics thrust belts in intersection zone Dabashan eastern Sichuan Basin based on seismic data, drilling field investigation zircon apatite (U-Th)/He thermochronology data. These data sets provide important insights into blocks during post-orogenic process. Due to...
The Brazil disk test is carried out for thin layered rock with different thickness by numerical simulation method, the load and AE data of samples analyzed.The following are some findings: (1) When a single layer increases, its tensile strength does not simply increase. Instead, they roughly show U-shaped relationship. (2) Layered rock's load-displacement curve multimodal. (3) Shear rupture occurs at upper lower ends disk, tensil mixed more frequently in middle disk. (4) There three stages...
Producing a sufficient volume of multiscale crack networks is key to enhancing recovery shale gas. The formation network largely depends on initiation and propagation microcracks. To reveal the influence different loading methods mineral‐scale microcracks, this study used Voronoi tessellation technique establish cohesive zone model mineral distribution applied six boundary conditions represent methods. Crack path characteristics, rupture continuous turning, en echelon intermittent under were...
