Abstract: In this paper, The use of the basic mechanics model, based on the use of fluid-structure coupling of thinking, the use of finite element software simulations, And Then quantitative study the effect of perforation parameters such as perforating depth, aperture,shooting density,shot phasing,drawdown on hole stability and well yield,make sure the weight size relationship of each perforation parameters about hole stability and well yield based on the orthogonal analysis. In the end based on the actual lithology information and original crustal stress distribution in longxi area of Daqing ,to design optimum perforating parameter of this block well.

Abstract: Mg, Ni and Cu nanoparticles were prepared by hydrogen plasma-metal reaction method. Nanostructured Mg2Ni and Mg2Ni0.75Cu0.25 compound were successfully obtained using the metal nanoparticles. The synthesis mechanism, the structure and lattice parameter difference, and the hydrogen absorption behaviors of the two compounds were discussed.
