Study on Compound Percussive Drilling: Rock‐Breaking Mechanism of High Confining Pressure Formation in the East China Sea

Energy Science &Engineering, EarlyView.
ABSTRACT The effect of improving the depth of penetration (ROP) in deep, high‐confining pressure formation is closely related to the rock‐breaking method, which has become a bottleneck restricting the efficient development of oil and gas. Based on the current engineering practice of the Xihu block in the East China Sea Basin, experimental research on ...

Distinguishing Rock Fracture and Pore's T2 Signals From NMR Experiments With Assisted X‐Ray CT Imaging

Energy Science &Engineering, EarlyView.
ABSTRACT Nuclear magnetic resonance (NMR) is widely used to characterize fluids in rock pore spaces, but traditional methods have difficulty distinguishing fractures from matrix pores in complex carbonate formations. To address this, we developed a calibration method that integrates X‐ray computed tomography (CT) imaging with NMR to identify fracture ...

Study on Energy Evolution Law of Rocks With Different Lithologies and Sizes

Energy Science &Engineering, EarlyView.
ABSTRACT Investigating the actual patterns of energy accumulation and release in roof rock, particularly with varying stiffnesses in mining environments, is crucial. By conducting cyclic loading and unloading tests on rock samples of different lithologies, different sizes, and consistent stiffness, how lithology, size, and stiffness affect the ...
