西宁盆地含坡缕石粘土赋存于第三系中,它由粘土矿物(伊利石、坡缕石、绿泥石等)、碳酸盐矿物(白云石、方解石)和陆源碎屑矿物(石英、长石、云母)组成。通过岩石化学统计相关系数和二次平差曲线对变化指数、相依系数、均方差研究,总结了坡缕石含量从东到西、从南到北增高的变化规律;碳氧同位素组成显示了湖相沉积特点,微量元素含量偏高,pH值8.75—9.23,反映了坡缕石形成环境为富镁弱碱—碱性的淡—咸水湖。研究了坡缕石的成矿地球化学作用,指出了寻找坡缕石的方向。 相似文献

The Maoshan area is an area with well-developed igneous rocks and complex structures. The thickness of the reservoirs is generally small. The study of the reservoirs is based on seismic data, logging data and geological data. Using techniques and software such as Voxelgeo, BCI, RM, DFM and AP, the authors have made a comprehensive analysis of the lateral variation of reservoir parameters in the Upper Shazu bed of the third member of the Palaeogene Funing Formation, and compiled the thickness map of the Shazu bed. Also, with the data from ANN, BCI and the abstracting method for seismic characteristic parameters in combination with the structural factors, the authors have tried the multi-parameter and multi-method prediction of petroleum, delineated the potential oil and gas areas and proposed two well sites. The prediction of oil and gas for Well JB2 turns out to be quite successful. 相似文献

This paper concerns the dynamic plastic response of a circular plate resting on fluid subjectedto a uniformly distributed rectangular load pulse with finite deformation.It is assumed that the fluid isincompressible and inviscous,and the plate is made of rigid-plastic material and simply supported along itsedge.By using the method of the Hankel integral transformation,the nonuniform fluid resistance is de-rived as the plate and the fluid is coupled.Finally,an analytic solution for a circular plate under a mediumload is obtained according to the equations of motion of the plate with finite deformation. 相似文献
