Chang 8 section reservoir characteristics and four properties relationship of Longdong region in Ordos basin

Triassic Chang 8 reservoir in Longdong region of Ordos basin is one of the most important exploration target layer, reservoir physical property is poor, diagenesis is complex, resulting in reservoir with strong heterogeneity, so the reservoir characteristic research work has become one of the research focuses. According to the regional geological background of the study area, hundreds of well logging, logging, core and oil testing data have been collected, collated, corrected, analyzed. Combined with the casting thin sections and scanning electron microscopy and other experimental observation, relevant maps in the study area is interpreted and made, a more detailed analysis has been made on low permeability characteristics and four properties relations.
