Conception of estabilishing the Sino-Russian border free economic region

So-called free economic region is a special region without jurisdiction of customs, delimited by one country. There are mainly four types of free economic region, that is, commercial type of free economic region —free port, industrial type of free economic region — export processing area, integrated commercial and trade type of free economic region — free trade zone, and scientific and technological type of free economic region — scientific industrial park. With the development of free economic region of different countries, besides free economic region within one country, there appear transnational border free economic region established by two or multiple countries. Analysing favorable factors and unfavorable factors to establish the free economic region for China and Russia, for example, China and Russia have land boundary line of 4282.7 km; China and Russia may strengthen overall cooperation in politics, military, economy, science and technology, culture, etc. making full use of geographical factors of the two countries, borders; there is a strong complementarity in resources, labour force etc. for China and Russia; strengthening the Sino-Russian economic trade cooperation is needed, the authors proposed a conception and selected four comparative ideal locations for establishing the Sino-Russian border free economic region: Manzhouli-Zabaikalye Free Economic Region, Heihe-Blagoveshchensk Free Economic Region, Suifenhe-Pogranichnyy Free Economic Region, Hunchun-Hasan Free Economic Region. Finally the principles and patterns for establishing free economic region are discussed.     

杭锦旗区块二叠系气层产能影响因素分析

杭锦旗区块上古生界二叠系发育了多套近源陆相碎屑岩沉积,自下而上存在着多套含气层砂体。储层具有中低孔低渗且纵横向非均质性较强等特征,致使气层需压裂改造后才具有一定产能。综合运用薄片、X衍射、压汞等实验资料及钻井测试成果,对气层的伤害、产能与探测半径和产能系数之间关系等进行分析研究,认为本区气层易受外来侵入流体污染,压裂规模和解堵有效程度将制约着气层产能。因此,若要有效改造气层和提高天然气产能,必须针对本区二叠系气层特有的特征,研究和采用合理的钻井技术、压裂工艺保护气层和加大压裂规模、扩大其渗流面等气层改造方法。     

南水北调西线区域多年冻土分布特征及其现象

南水北调西线区域处于高原连续片状冻土区向高山不连续岛状冻土区过渡的中间地带。区域内多年片状冻土、岛状冻土和季节性冻土三种类型并存,造成了冻土分布的复杂性与多变性。依据大量实际资料,系统论述了区域内冻土、地下冰、融区的分布与特征,冻胀与融沉的各种现象。     

崤山地区太古代变质花岗岩地质地球化学特征

崤山地区原“太华群”由１５％的变质表壳岩和８５％的变质花岗岩组成。变质花岗岩的主要岩石类型有：石英闪长岩、英云闪长岩、奥长花岗岩、花岗闪长岩。通过对变质花岗岩的地质、地球化学研究表明，崤山地区太古代变质花岗岩与国内外其他地区的ＴＴＧ岩系类似。根据野外接触关系和一组锆石Ｐｂ－Ｐｂ蒸发年龄（２４５１Ｍａ），确定其成岩时代为太古代。     

塔尔水源地水文地质特征及开采前景分析

本文在分析塔尔水源地水文地质特征的基础上,通过对地下水资源、开采现状、含水层贮存调节功能和动态等分析和论证,认为按现状开采,水源地未完全发挥其应有效益,尚有扩大开采的潜力,并提出了扩大开采的方案。     

南水北调西线区域地壳稳定性评价思路和地壳现代构造应力场及块断作用

区域地壳活动性受区域构造应力场控制。通过南水北调西线区域及邻区34个中强地震的震源机制解,对区域内现代构造应力场进行了分析。结合地球物理资料,对西线区域的边界断裂及其活动性进行了评估。将测区青康滇楔状地壳断块体,划分为鄂陵湖—龙门山和西金乌兰湖—贡嘎山两个次级断块,分析了它们的块断作用。
