基于广义Kопытов模型及乙型水驱曲线的综合预测法

将广义Kопытов预测模型和乙型水驱曲线方法有机的结合起来，得到了油田开发中后期——递减时期的一种预测水驱开发油田的含水率、产油量、产水量及其相应的累积产量随开发时间变化的方法，此方法克服了在水驱油田预测开发指标中二者所存在的局限性。     

北衙金矿成矿地质条件浅析

北衙金矿与构造、岩浆活动、沉积建造、围岩蚀变等关系密切。构造具多期次活动特点，近NS向断裂控制主矿体展布。岩浆活动具多个喷发旋回。金矿体赋存于褐铁矿体(层)中，产出空间和时间上与正长斑岩有密切的成生关系。磁异常值较高地段，预示着有褐铁矿体(层)存在。化探异常的浓集区，均指示金矿的存在。

四川盆地碳酸盐岩油气勘探实践与认识

四川盆地烃源十分丰富。但油气演化程度高,大多已进入高成熟和过成熟阶段,至今只在侏罗系发现有油藏,三叠系及其更老地层皆为气藏。储层主要为碳酸盐岩,其特点是低孔低渗,平均孔隙度仅1.7%,平均渗透率小于1×10~(-3)μm~2,但其中的“孔洞发育层段”平均孔隙度可达3%～6%。根据四十年的勘探经验,加强预探并争取新发现是四川盆地油气勘探发展的关键。预探中,按构造带规划大中型气田勘探目标,将成藏条件相似、地域上相邻的局部圈闭群作为一个整体勘探对象,实行稀井广探,少井高效。“八五”以来,在高陡构造带勘探技术、储层横向预探技术等方面有长足的进步,勘探成效不断提高,实现了资源序列的良性循环。

云南楚雄盆地上三叠统沉积及地球化学的海相特征

楚雄盆地为中生代形成的典型前陆盆地。三叠纪是其形成的主体阶段和盆山转换的重要时期,也是由海相向陆相沉积环境的转折期,同时上三叠统是楚雄盆地最重要的油气资源层系。通过对楚雄盆地上三叠统进行系统的沉积学、层序地层学和波动地质学分析,在上三叠统识别出3个三级层序,建立了层序地层格架和高频波动曲线。对层序地层格架内的碳、氧同位素和微量元素的特征进行分析,发现楚雄盆地晚三叠世诺利晚期—瑞替期沉积具有海相沉积环境的地球化学特征,同时综合多学科的研究成果,指出楚雄盆地该时期为一与海域相接的近海湖盆,并受到间歇性海侵的影响。而海相烃源岩与陆相烃源岩在生烃能力、分布规律等方面均具有较大的差异。因此,这一认识对于重新评价楚雄盆地晚三叠世烃源岩具有重要意义。     

植物中单体烷烃碳同位素组成与其生长环境的关系

用色谱一同位素质谱议对青藏高原东北部高寒草甸生态系统中的两种高等模特一火绒草（Ｌｅｏｎｔｏｐｏｄｉｕｍ ｌｅｏｎｔｏｐｏｄｉｏｉｄｉｅｓ）和蒲公英（Ｔａｒａｘａｃｕｍ ｍｏｎｇｏｌｉｕｍ）的烷烃进行分析,讨论环境因素对植物单体烷烃碳同位素组成（δ＾１３Ｃｉａ）的影响。研究发现,两种植物奇碳数正构烷烃的δ＾１３Ｃｉａ值都比较小,且有随海拔高度的增加而增大的趋势,而偶碳数正构烷烃的δ＾１３Ｃｉａ值可能     

Qinling Faunal Region-The Third Ordovician Faunal Region: International Correlation

The Ordovician conodont faunal provinces were previously divided into the Midcontinent and Atlantic Faunal Regions situated respectively in low and high latitudes, where warm- and cold-water type conodont faunas flourished respectively. According to the international correlation this paper proposes the third Ordovician conodont faunal region-Qinling Faunal Region, in which cold-water conodont faunas were well developed in the Early to middle Middle Ordovician and warm-water conodont faunas were well developed in the late Middle and Late Ordovician, indicating that the Qinling Region was situated in high latitudes earlier and in low latitudes later. The origin was only due to plate movement In the Qinling Region the time interval of the change of the conodont fauna from the cold- to warm-water type was 4 Ma (from 474 to 470 Ma), during which the fauna geographically spanned 40° of latitudes, with a movement velocity of nearly 1.12 m/a, indicating that the high-latitude plates were divorced and reduced i

Limits to comprehensive planning

This paper postulates that larger more complicated organisms cannot be comprehended completely. Some of their important internal characteristics and dynamics are indeterminate. Certain external conditions and occurrences vitally affecting them cannot be predicted or treated as random events. The internal functioning of complex organisms and their interaction with the external environment cannot therefore be formulated analytically with the completeness, precision, and reliability required for truly comprehensive planning and decision-making. Limitations of rational and collective action by people are also involved in what comprehensive planning can and cannot accomplish, and how it is best conducted.
