Materials and Methods Investigation time and site.
The results of comprehensive quality index evaluation method of Water quality showed that four reef site index is greater than 1, in the slight pollution levels. so it indicated that this sea water, especially reef site still exists the risk of contamination, Except considering the external environmental factors, It is important to examine whether the reef itself have lasting impact on the environment or not, so as to gradually improve and optimize the design of the reefs and materials.

So their homologies were very well likely because the soil samples had the same parent material, rock or similar soil chemical process, and they were more likely to take on combined pollution.

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

Diagram of the model Kinetic energy of the beam with attached solid body may be described in the following form: (2.1) where is the density of beam material and is the mass of solid body.
As a result, the similarity conditions were obtained, that have to be fulfilled by the introduced similarity scales factors, the geometrical parameters, and the material properties of full-size object and its model.

Introduction
In the continuous casting process, the internal defects which can be formed in cast material are due to inappropriate casting operation and improper secondary cooling water distribution, especially the defects of cracks represented by the midway crack and centreline crack which cover over 50% of total quality problems[1,2].
