Typical methods for oil flow simulation in dual-continuum porous media cannot be used straightforward to this kind of simulation due to the artificial mass loss caused by the compressibility and the non-robustness caused by the non-linear source term. To avoid these two problems, corrected numerical methods are proposed using mass balance equations and local linearization of the non-linear source term. The improved numerical methods are successful for the computation of gas flow in the double-porosity double-permeability porous media. After this improvement, temporal advancement for each time step includes three fractional steps: (i) advance matrix pressure and fracture pressure using the typical computation; (ii) solve the mass balance equation system for mean pressures; (iii) correct pressures in (i) by mean pressures in (ii). Numerical results show that mass conservation of gas for the whole domain is guaranteed while the numerical computation is robust. dc.description.sponsorship The work presented in this paper has been supported by National Natural Science Foundation of China (NSFC) (No. 51576210, No. 51676208), Science Foundation of China University of Petroleum-Beijing (No. 2462015BJB03), and also supported in part by funding from King Abdullah University of Science and Technology (KAUST) through the grant BAS/1/1351-01-01. dc.publisher Springer Nature dc.relation.url https://link.springer.com/chapter/10.1007%2F978-3-319-93713-7_10 dc.rights Archived with thanks to Computational Science – ICCS 2018 dc.subject Double-porosity double-permeability dc.subject Fractured porous media dc.subject Gas flow dc.subject Mass conservation dc.subject Numerical method dc.title Study on Numerical Methods for Gas Flow Simulation Using Double-Porosity Double-Permeability Model dc.type Conference Paper dc.contributor.department Computational Transport Phenomena Lab dc.contributor.department Earth Science and Engineering Program dc.contributor.department Physical Science and Engineering (PSE) Division dc.identifier.journal Computational Science – ICCS 2018 dc.conference.date 2018-06-11 to 2018-06-13 dc.conference.name 18th International Conference on Computational Science, ICCS 2018 dc.conference.location Wuxi, CHN dc.eprint.version Post-print dc.contributor.institution National Engineering Laboratory for Pipeline Safety, MOE Key Laboratory of Petroleum Engineering, Beijing Key Laboratory of Urban Oil and Gas Distribution Technology, China University of Petroleum (Beijing), Beijing, 102249, , China dc.contributor.institution Department of Thermal Energy and Power Engineering, College of Pipeline and Civil Engineering, China University of Petroleum (Qingdao), Qingdao, Shandong, 266580, , China kaust.person Sun, Shuyu kaust.grant.number BAS/1/1351-01-01 refterms.dateFOA 2018-08-29T08:09:45Z dc.date.published-online 2018-06-12 dc.date.published-print 2018
