It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.
矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果,包括地壳运动,火山爆发,沉积作用,冰河作用和风化等等,在这些作用下,生成了火成岩,火山杂岩,水成岩和沉积岩等,一些矿石是由于这些作用共同形成的,这就是自然界中没有纯净矿石的原因。由于这些原因的存在,需要用分离技术和器械,也就是矿石加工设备对矿石进行的分割,迄今为止这些矿石加工设备已经不能够满足冶金工业的需要,科学家们力图用激光把冶金工业提高到一个新的水平。

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1~N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.
