To develop the in situ underground pyrolysis process of tar-rich coal more scientifically, effect temperature and pressure on distribution products should be clarified. This paper selected typical components five distillates light tar, phenol naphthalene washing anthracene tar as main reaction products. 32 secondary reactions were constructed. Based thermodynamic analysis strategy, variation Gibbs free energy equilibrium constant was investigated. The results showed that mainly affected...
Downhole electric heater studied in this paper is used for tar-rich coal in-situ conversion, and the closed double-shell structure proposed to improve performance economy of heater. In paper, four downhole heaters were experimentally studied, single-shell was as control. According experimental results, it can be seen that mass flow rate has a great impact on total cost, parallel highest cost. addition, larger helical pitch or shell diameter, lower surface temperature, thermal radiant main...
The Lower Paleozoic reservoir in the Micangshan tectonic zone is a new shale gas exploration area with excellent potential. However, hydrocarbon migration and accumulation histories of this have not been thoroughly elucidated urgently require further research. Fluid inclusions offer unique useful method to test for migration, accumulation, composition timing. This study integrated charge history using fluid Cambrian Neoproterozoic from zone. work involves delineation analysis petrography,...
Currently, depth sequences generated by automatic estimation suffer from the temporal inconsistency problem. Estimated values of some objects vary in adjacent frames, whereas actually remain on same planes. These errors significantly impair visual quality synthesized virtual view as well coding efficiency sequences. Since correspond to texture sequences, erroneous variations can be detected analyzing Utilizing this property, we propose a novel solution enhance consistency applying adaptive...
Abstract The gas generation features of coals at different maturities were studied by the anhydrous pyrolysis Jurassic coal from Minhe Basin in sealed gold tubes 50 MPa. component yields (C 1 , C 2 3 i -C 4 n 5 and CO ); δ 13 ; mass liquid hydrocarbons 6+ ) measured. On basis these data, stage changes calculated. diagrams – vs ln /C used to evaluate maturity stages. At high evolution ( T > 527.6 °C °C/h), change CH yield are much higher than that suggesting could still generate methane....
There are vast resources of oil shale in the Chang-7 section Upper Triasic Yanchang Formation, Ordos Basin, China. They would provide secure access to transportation fuels, if utilized an effective, economic and environmental manner. A sample containing pyrite has been pyrolysed a thermogravimetric analyzer at constant heating rates 5, 10, 20℃/min up 1150℃ with nitrogen as purge gas. Meanwhile, pyrolysis-gas chromatograph-mass spectrometry experiments were performed on parallel samples four...
The correct understanding of shale pore characteristics is the foundation gas exploration and development. Comminution an essential sample pretreatment in many measurements characteristics, but little known about influence comminution on characteristics. This study utilizes low-pressure nitrogen adsorption helium porosity to investigate evolution during comminution. results show that reducing proportion inaccessible pores improving diffusion efficiency are main effects resulting increase...
The Micangshan-Dabashan tectonic belt, located in the southern Qinling-Dabie Orogen near northeastern Tibetan Plateau, is a crucial area for understanding processes and mechanisms of orogenesis. Previous studies have been focused on cooling process via thermochronology mechanism basement uplift investigated. However, coupling exhumation sedimentary cap unclear. tectono-thermal history constrained by detrital apatite fission track (AFT) results could provide valuable information crustal...
The characteristic of biomarker, stable carbon isotope, and rare earth elements in solid bitumen from the Puguang gas field organic fraction source rocks same area were investigated. Results show that was derived a mixed with greater contributions marine materials deposited under reducing environments. enrichment light seemed related to matter input. According results principal component analysis, main paleo-oil reservoir Upper Permian rocks.
The Lower Paleozoic reservoir in the Micangshan tectonic belt is a new shale gas exploration area with excellent potential. However, black shale’s sedimentary environment and setting their effects on pore-scale fluid flow have not been thoroughly elucidated urgently require further research. A large amount of trace rare earth element data this was tested to analyze sediment’s provenance, setting, coupling process, nuclear magnetic resonance applied for ability determination. characteristics...
In order to investigate the effects of water pressure on hydrocarbon yields and potential in source rocks, carbonaceous mudstone from drilling Liaohe Basin was pyrolyzed simulation with constant high-water-pressure experiments. Results demonstrate that times expelling remarkably promote rocks yielding liquid hydrocarbons. Increasing may increase reaction generating bitumen oil, enhance hydrocarbons generation. TOC, Rock-Eval, elemental analysis this study suggest dominated by type-III...
Abstract Residual bitumen in organic‐rich shale of oil windows exists widely, and its effect on the gas storage capacity could be two‐fold. Bitumen occupy block nanopores shale, thereby reducing capacity. On other hand, dissolved reservoirs, leading to enhanced To quantify gas‐in‐place (GIP) estimation lacustrine micropore characteristics methane sorption original bitumen‐free from Triassic Yangchang Formation Ordos Basin, combined with dissolution for isolated bitumen, were analyzed...
