Factors influencing productivity and production system optimization for deep coalbed methane in the Daning-Jixian block, Ordos Basin

Meitian dizhi yu kantan
ObjectiveDeep coalbed methane (CBM) reservoirs are characterized by ultra-low porosity, ultra-low permeability, and super saturation, rendering it impractical to copy the productivity models of shallow coalbed methane and shale gas.

Moho Depth Variations From Receiver Function Imaging in the Northeastern North China Craton and Its Tectonic Implications [PDF]

, 2019
A detailed knowledge of the crustal thickness in the northeastern North China Craton (NCC) is important for understanding the unusual Phanerozoic destruction of the craton. We achieve this goal by employing a 2‐D wave equation‐based migration method to P
