At the Changning block and at Luzhou block, genetic mechanism of low-resistivity shale its impact on reservoir quality are currently a hot topic world-wide scale. Shale with resistivity lower than 20 Ω·m is widely developed Wufeng-Longmaxi Formation in Southern Sichuan Basin, bringing considerable challenge for prediction using electromagnetic method. This paper discusses mechanisms qualities t...

Abstract The production of thin-wall ductile iron (TWDI) by high-pressure die-casting (HPDC) is complex because several metallurgical and microstructural challenges. present work aims to evaluate the austemperability components (4 mm thickness) produced HPDC process. graphitization kinetics, pearlite formation during continuous cooling, effect austempering on evolution ausferritic microstructur...
