Pore Structure and Heterogeneity Characteristics of Deep Coal Reservoirs: A Case Study of the Daning–Jixian Block on the Southeastern Margin of the Ordos Basin

Minerals (Basel, Switzerland)
To clarify the micropore structure and fractal characteristics of the Danning–Jixian block on the eastern margin of the Ordos Basin, this study focuses on the deep coal rock of the Benxi Formation in that area. On the basis of an analysis of coal quality and physical properties, qualitative and quantitative studies of pore structures with different ...

Characterisation of the Full Pore Size Distribution of and Factors Influencing Deep Coal Reservoirs: A Case Study of the Benxi Formation in the Daning–Jixian Block at the Southeastern Margin of the Ordos Basin

Processes
The complex geological environment in deep layers results in differences in the pore and fracture structures and states of coalbed methane (CBM) occurrences between deep and shallow coal reservoirs. The coexistence of multiphase gases endows deep CBM with both “conventional” and “unconventional” geological attributes.

Acid Fracturing-Induced Fracture Propagation in Deep Coalbed Methane Wells: A Case Study in Daning-Jixian Block

Petrophysics – The SPWLA Journal of Formation Evaluation and Reservoir Description
Acid fracturing technology in coal seams has been proven to be an efficient coalbed methane (CBM) mining method. With the development of research, acid fracturing technology has become a hot research topic. Here, the deep No. 8 coal seam in the Daning-Jixian of the Ordos Basin is taken as the object of study.
