Future gas field development and prospect assessment depend on accurate reservoir parameter characterization. The understanding of the tight sand distribution Shanxi Taiyuan Formations within Hangjinqi area is ambiguous due to presence coal mudstone lithofacies, high heterogeneity, poor resolution seismic data. Thus, it difficult determine reservoir’s thickness. To cope with this challenge, we ...

In this paper we present three modified parallel multisplitting iterative methods for solving non-Hermitian positive definite systems Ax = b . The first is a direct generalization of the standard parallel multisplitting iterative method for solving this class of systems. The other two are the iterative methods obtained by optimizing the weighting matrices based on the sparsity of the coefficien...

In this study, CO2 seepage of sandstone samples from the Taiyuan-Shanxi Formation coal seam roof in Ordos Basin, China, under temperature-stress coupling was studied with aid TAWD-2000 rock mechanics-seepage test system. Furthermore, evolution law and influencing factors on permeability for temperature axial pressure were systematically analyzed. The results disclose that decreases increase str...

The genetic types and source of the Lower Paleozoic natural gas in Ordos Basin China are controversial, geochemical characteristics light hydrocarbons fifth member Ordovician Majiagou Formation (O 1 m 5 ) studied by taking Daniudi field as an example, order to reveal origin source. C 5−7 dominated iso-alkanes rather than n-alkanes, methyl cyclohexane (MCH) content is mostly higher nC 7 hydrocar...
