For upgrading the liquid distribution in a trickle‐bed reactor, the distributor is always the primary consideration. The vapour‐lift tube device, most widely used in industry, still has disadvantages like mal‐distribution to overcome. Therefore in this paper, two major modifications, that is increasing of slot numbers and opening side pores, were proposed to improve its liquid distribution performance...
Full 3D interpretation must be based on really full 3D horizons interpretation. In this paper, we used mathematical model of the similarity principle which express the characterization of the waveform similarity of seismic data, and we analyzed the effect of model parameters on the waveform similarity recognition, then we applied this method to auto-track the reflected wave of coalseam in the 3D seismic...
