Mechanical response of kerogen at high strain rates

• A new kerogen aggregate with Gaussian molecular weight distribution was established. The dynamic response of obtained under different strain rates. microscopic mechanism the plastic stress oscillation and fracture clarified. compressible hyper-viscoelastic constitutive model built to describe mechanical behaviour aggregate. As main organic component shale, has a direct impact on shale reservoirs. is used study kerogen, which rational conforming distribution. rates by using dynamics simulations. results show that shows material hardening decrease rate. In range, we analyse causes at level, obtain relationship between hydrogen bond. established, describes Our research provides valuable insight in properties, helps understand reservoirs from micro-perspective.
