Research on in-situ condition preserved coring and testing systems

Petroleum Science, Journal Year: 2021, Volume and Issue: 18(6), P. 1840 - 1859

Published: Nov. 10, 2021

As shallow resources are increasingly depleted, the mechanics' theory and testing technology of deep in-situ rock has become urgent. Traditional coring technologies obtain samples without retaining environmental conditions, leading to distortion measured parameters. Herein, a systems geological conditions is presented: system that obtains samples, transfer stores analyzes rocks under reconstructed environment. The ICP-Coring mainly consists pressure controller, active insulated core reactor insulation layer sealing film. ultimate bearing strength 100 MPa for pressure-preservation, temperature control accuracy 0.97% temperature-retained realized. CH4 CO permeability optimized film as low 3.85 0.33 ppm/min. average tensile elongation 152.4% light transmittance reduced 0%. Additionally, steady-state reconstructing environment storage up 1% ±0.2 achieved. error recorded noncontact sensor ring made low-density polymer less than 6% contact test. can provide technical support mechanics research, improving resource acquisition capabilities further clarifying deep-earth processes.

Experimental study on seepage characteristics and stress sensitivity of desulfurization gypsum based concrete under triaxial stress

Journal of Materials Research and Technology, Journal Year: 2023, Volume and Issue: 24, P. 6425 - 6437

Published: April 29, 2023

Converting industrial by-products into green building materials is critical to achieve a low-carbon circular economy. Permeability an important characteristic of material that can affect its various engineering applications. Therefore, this study investigated seepage characteristics and stress sensitivity material, i.e., modified desulfurization gypsum based concrete. Different initial load damage dry-wet-freeze-thaw alternating cycle test groups were established by simulating the service environment. evolution specimens under different states during loading unloading confining pressure was obtained. The phase divided high sensitive, medium low sensitive areas according coefficient, where corresponding permeability decreased rapidly, moderately, slowly. recovery degree increased gradually with decrease in stage. However, value generally lower than stage due plastic deformation pores specimens. higher more number cycles, greater loss rate Combined nuclear magnetic resonance results, it found environmental factors development pore structure each size specimens, resulting recovery. T2 relaxation time curve shifted left pressure, indicating became smaller, channel narrower, decreased.
