Abstract The Upper Paleozoic (Carboniferous to Permian) succession in the east margin of Ordos Basin North China Craton has a potential contain significant hydrocarbon resources, though attention have been mainly attracted for its successful development coalbed methane (CBM). To improve previous resource estimates and evaluate play possibilities, this study incorporated new discoveries units their stratigraphic relation with source rocks, migration trapping configurations. Continuous...
Abstract Coal-water interactions have profound influences on gas extraction from coal and utilization. Experimental measurements three coals using X-ray photoelectron spectroscopy (XPS), low-temperature nitrogen adsorption dynamic water vapor sorption (DVS) were conducted. A mechanism-based isotherm model was proposed to estimate the uptake at various relative humidities, which is well validated with DVS data. The of further used derive isosteric heat sorption. specific surface area pores...
The coal strength and deformation properties are key factors affecting safe mining high-efficiency coalbed methane (CBM) development. In this paper, reconstituted samples chosen to investigate the weakening behavior of gas on strength, meanwhile, its effects quantitatively evaluated. results indicate that degree is closely related confining stress pressure. Compared with non-gas-saturated coals, maximum ratios adsorbed 10.58%, 18.12%, 8.55% 14.65% under conditions CS = 3 MPa pressure GP 1...
Abstract Hydraulic fracturing and permeability enhancement are effective methods to improve low-permeability coal seams. However, few studies focused on increase permeability, there no suitable prediction for engineering applications. In this work, PFC2D software was used simulate seam hydraulic fracturing. The results were in a coupled mathematical model of the interaction between deformation gas flow. show that displacement velocity particles direction minimum principal stress, cracks...
CO2/N2-enhanced coalbed methane recovery is an important means of increasing production, and understanding the competitive adsorption CO2, CH4 N2 in coalbeds its impact on coal properties important. A structural model for anthracite from Daning-Jixian was constructed based elemental analyses, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy carbon nuclear magnetic resonance data. The grand canonical Monte Carlo method used to research multiple gases changes porosity...
