In order to achieve efficient and reasonable development in the situation of horizontal well's widely application in oil and gas reservoirs, further research of horizontal well should be conducted. Researches about horizontal well mainly aimed at productivity while fewer on the development dynamic. The linear horizontal-vertical well pattern model is built, combined with two-phase flow theory the...
This paper mainly proposes a neural networks model with hybrid algorithm, named HAENN (Hybrid Algorithm Elman Neural Network). This model is based on Elman neural network, using an improved algorithm instead the standard BP training algorithm. This improved algorithm is combined Particle Swarm Optimization algorithm with Simulated Annealing's idea, which has faster convergence speed and better solution...
Asphalt concrete is a porous and no uniform material; air void always plays an important role in asphalt concrete quality control. This study describes a new analytical method to quantify the air voids on section surface of asphalt mixes based on image analysis. This study establish a credible relationship of natural logarithmic between the micro index from this new measurement and traditional macro...
