Introduction
During the last decades, recycling of a wide array of materials, ranging from food product waste to advanced products such as cars and computers has become part of everyday life [1].
The key technology definition given by the White House office of science and technology policy is: the technologies essential to America's economic prosperity and national security.
China Academic Journal is selected for this purpose in this study.
Although the production of recycled aluminum looks very simple, in fact, it is a system of engineering with numerous processes, including raw materials procurement, sorting, melting, ingot casting, as well as equipment and technology management and other important links.

Abstract.
Rock types and mineralization characteristics.From the analysis of well logging , core , slice data of Lun 1 , Lun 2 , Lun 3 , Lun 4 , Lun 5, the main rock types include:Multi-composition sandy conglomerate; gravel–bearing sandstone ;conglomerate limestone,lithic sandstone, gray quartz–siltstone grip sparry limestone and so on.The content of quartz in mineral detritus is high , the average contents of it in fine,slit quartz-stone is 70% and low feldspar content.The contents of detritus is high ,it is about 60% in sandy conglomerate ,and types complex .Volcanic debris and limy dolomite are main contents, fine–siltstones are followly,these feature reflect rapid subsidence and near–shore sedimentary environment.Cement and argillaceous matrix are the mainly form of interstitial material .The mainly cement is calcite and few kaolinite.
Sandly conglomerate is the main components in target bed of Niubao Formation and Dinqing lake formation .Particle size coarse,well mechanical compaction resistance and the compaction is showde by the rupture of clastic grain along the weakness structure plane of its surface, microfissure and filled with other interstitial material . 2, Pressure solution While in Sandstone ,the content of feldspar , debris and other fragile components is high .Besides it , the poor ability of resist—compaction caused by low structure maturity, compaction often associated with pressolution and it showed in Fig.1,Point—line contact and concave convex contact are the main contact between grains ,besides it some pores are inserted or pierced by coarse grains .It makes great impact on the reservoir decrease when the plastic materials deformation or intersection Fig.1 The core of Well A in plane polarized light 3.Cementation The temperature and pressure is rise whith the increase buried depth of reservoirs

Hot pressing of powders prepared by mechanical alloying is widely used in powder metallurgy as a kind of very good method to obtain nanocrystalline bulk materials with very good densification [1-11].
Nanocrystalline materials can cause surface effect, quantum size effect, small-size effect and macroscopic quantum tunnel effect.
Thus, they have many unique properties different from those of tradition materials and become a hot subject in research of material sciences [17].
