论山东东营、惠民盆地油田水与油气聚集关系

山东东营、惠民盆地的油源断裂,即沟通生油岩与非生油岩的同生断裂发育区,出现了油田水的高含盐度分布带。它不仅与已知油气藏的分布相一致,而且水的含盐度异常值与石油储量之间呈正相关。笔者以东辛、现河庄和临商油田为例,分析了油田水与油气藏形成的成因和伴生关系,还用相关曲线定量预测了盆地新区石油地质储量,并经钻探证实其可靠性。     

Definition of subfossil meandering palaeochannels

The determination of the bottom of a subfossil meandering palaeochannel is important for investigations of the palaeohydrology of valley bottoms, and crucial for the quantitative estimation of past river discharges. The authors present a procedure on the basis of which the bottom of a palaeochannel can be precisely determined. It is based on an analysis of the stratigraphic variability of such features of deposits as: mean diameter, standard deviation of the grain-size composition, the percentage of sand, and ignition loss.     

Development of Artificial Intelligence Technology in Weather Forecast

Numerical weather prediction, which is the major basis of current weather forecast, has some shortcomings, such as the understanding of the law of atmospheric motion, the assimilation and application of observation data, the expression of model physics, etc., leading to the forecast error of weather. The rapid development of artificial intelligence technology in recent years provides a new possibility for the advancement and innovation of weather forecast. In this paper, the background of the development of artificial intelligence, the current situation of the application of artificial intelligence technology to weather forecast and the future development trend are mainly described to account for this possibility. After that, the idea for development of weather forecast technology based on the integration of artificial intelligence and numerical forecast is put forward. Particularly, this study stresses that, in order to advance the AI algorithm of weather forecast in the future, it is requested to focus on the nonlinear and chaotic characteristics of atmospheric motion leading to the uncertainty of forecast. Starting from the essence of mathematics and physics, we need to realize the hybrid modeling of mathematics and physics, not only to establish the framework of input-output mapping, but also to provide solutions to the bottleneck problems of weather forecast.     

塔里木盆地北部油气田水文地质及水文地球化学特征

以实测的流体资料为基础，初步揭示了塔北地区油田水文地质和水文地球化学特征。塔北地区存在两股地下水流，南部生油区为压实水流，由南向北流动，北部为重力水流，由北向南流动，这两股水流交汇于雅克拉和轮南地区，向上封闭式内泄。无论重力水流或压实水流，皆为非海相成因、非浓缩成因溶滤水。表明：油气藏的形成绝大部分是寒武－奥陶纪生油层二次成油的结果。     

安太堡露天煤矿排土场基底黄土的微结构演化与弱层的形成机理

本文根据安太堡露天煤矿排土场基底黄土的粘土矿物组成的微结构及其在分级荷载下微结构变化的研究，论述了排土场基底黄土内弱层的形成机理，提出弱层是在上覆排土压力下由于黄土的微结构变化而形成的演化弱层。并指出弱层的形成是导致排土场失稳滑坡的主要控制因素，这种弱层在新排土场设计时期并不存在，极具隐蔽性，但在设计时必须考虑在排土增至一定高度后，弱层的形成对排土场稳定性的影响，否则必将会存在重大滑坡隐患。     

邢台地震房屋破坏率的正态性X￣2检验

对１９６６年３月８日和３月２２日台地震中的房屋破坏情况进行统计，计算了地震区主要房屋土坯墙房在Ⅳ～Ⅸ度中的毁坏率、严重破坏率和中等破坏率。通过Ｘ￣２检验得出，Ⅵ度和Ⅸ度区房屋毁坏率、严重破坏率和中等破坏率的分布均服从正态分布
