The influences of perforating phase and bedding planes on the fracture deflection in laminated shale

Petroleum Science 2024年第2期21卷 1221-1230页

The perforating phase leads to complex and diverse hydraulic fracture propagation behaviors in laminated shale formations. In this paper, a 2D high-speed imaging scheme which can capture the interaction between perforating phase and natural shale bedding planes was proposed. The phase field method was used to simulate the same conditions as in the experiment for verification and hydraulic fracture propagation mechanism under the competition of perforating phase and bedding planes was *** results indicate that the bedding planes appear to be no influence on fracture propagation while the perforating phase is perpendicular to the bedding planes, and the fracture propagates along the perforating phase without deflection. When the perforating phase algins with the bedding planes, the fracture initiation pressure reserves the lowest value, and no deflection occurs during fracture propagation. When the perforating phase is the angle 45°, 60°and 75°of bedding planes, the bedding planes begin to play a key role on the fracture deflection. The maximum deflection degree is reached at the perforating phase of75°. Numerical simulation provides evidence that the existence of shale bedding planes is not exactly equivalent to anisotropy for fracture propagation and the difference of mechanical properties between different shale layers is the fundamental reason for fracture deflection. The findings help to understand the intrinsic characteristics of shale and provide a theoretical basis for the optimization design of field perforation parameters.

Pseudo-dynamic testing of a fabricated composite frame with steel plate shear walls

Journal of zhejiang University-Science A(Applied Physics & Engineering) 2017年第6期18卷 454-466页

作者： zheng-gang CAO Peng DU Feng FAN zhe-ming chen Key Lab of Structures Dynamic Behavior and Control of the Ministry of Education Harbin Institute of Technology Harbin 150090 China School of Civil Engineering Harbin Institute of Technology Harbin 150090 China Shanghai Municipal Engineering Design Institute (Group) Co. Ltd Shanghai 200092 China

A pseudo-dynamic testing program was generated on a fabricated composite frame with steel plate shear walls （SPSWs） to study its seismic perlbrmance. The specimen was a three-storey single-bay frame, which was composed of H- section steel columns and composite beams, and was assembled by bolted height-adjustable steel beam-to-column connections （BHA connections）. Beam-only-connected SPSWs were selected as lateral load resisting members. The specimen was subjected to four ground motions of progressively increasing intensity. The results showed that：（1） beam-only-connected S PSWs provided sufficient lateral load resistance, lateral stiffness, and energy dissipation capacity to the fabricated frame via the tension ficld action developed in their infill panels; （2） the fabricated frame, assembled by BHA connections, exhibited substantial redundancy and good ductility; （3） an undesirable failure mode of the fabricated frame, in huge earthquakes, included severe cracking in composite beams and block shear failure in SPSWs＇ connections; （4） the inter-storey shear force distribution determined by ASCE/SE1 7-10 was verified with experimental data.
