Research and Application of Personalized PDC Bits for Longmaxi Formation in Changning, Sichuan Basin

Academic Journal of Science and Technology
The Longmaxi Formation in the Changning Block of the Sichuan Basin has a large reservoir thickness and is a high-quality shale for the main shale gas bearing target layer. However, problems such as high rock strength, high drillability level, and large horizontal drilling length in the Longmaxi Formation have led to rapid failure of the drill bit and ...

Tectonic Impact on Organic Matter Enrichment in Paleozoic Marine Shales from the Yangtze Block, SW China

Journal of Marine Science and Engineering
The enrichment of organic matter in marine shale is a complex process involving tectonic–sedimentary interactions. The tectonic setting exerts critical control over sediment provenance, marine biota, and subaqueous environmental conditions in shale ...

A comparative experimental study of shale indentation fragmentation mechanism at the macroscale and mesoscale

Advances in Mechanical Engineering, 2017
Low drilling rate is one of the key difficulties in shale formation, but the shale fracture mechanism during drilling operation is unclear. The shale dynamic fragmentation and crack from the multiscale perspective need to be studied.
