Abstract For a superdeep imbricated thrust-fold belt in the Kuqa depression of Tarim Basin, NW China, structural fractures have great impact on tight gas reservoir productivity. In this research, were characterized from core data and imaging logging data. Numerically, finite element (FE) method was applied to simulate 3-D paleotectonic stress field key fracture-generating period as well present-day Keshen field. Based previously developed geomechanical models, we further derived models...
In this paper, a parameter self-learning multivariable active disturbance rejection control (ADRC) algorithm is proposed for the Diesel engine air system equipped with variable exhaust gas turbocharger (VGT), recirculation (EGR), and intake throttle valve (TVA). Firstly, based on principle of simplified operation, three-in-three-out linear prediction model established, deviation equivalent to total disturbance. A extended state observer employed observation enhance model's adaptability....
ABSTRACT: This study investigates the relationship between capital market opening and related party transactions (RPT) of listed companies, exploiting a quasi-natural experiment. The results show that effectively inhibited such by increasing information transparency companies improving their operating conditions. In with small boards directors large-scale transactions, inhibitive effects are more pronounced. paper enriches research on consequences factors affecting RPT. It also provides...
A new method is used to quantify the relationships between stress field and primary fracture characters (aperture, density) in low-permeability sandstone reservoirs based on laboratory experiments mathematical development, through which, quantitative modeling set up. Using this modeling, we can load it into analysis software (Ansys 10.0) acquire 3D palaeo current-stress after selecting appropriate mechanical parameters loading.
