A Method for Determining Sedimentary Micro-Facies Belts Automatically     

Linfu Xue  Qitai Mei  Quan Sun 《世界地质(英文版)》2003,6(1)

It is important to understand the distribution of sedimentary facies, especially the distribution of sand body that is the key for oil production and exploration. The secondary oil recovery requires analyzing a great deal of data accumulated within decades of oil field development. At many cases sedimentary micro-facies maps need to be reconstructed and redrawn frequently, which is time-consuming and heavy. This paper presents an integrated approach for determining the distribution of sedimentary micro-facies, tracing the micro-facies boundary, and drawing the map of sedimentary micro-facies belts automatically by computer technique. The approach is based on the division and correlation of strata of multiple wells as well as analysis of sedimentary facies. The approach includes transform, gridding, interpolation, superposing, searching boundary and drawing the map of sedimentary facies belts, and employs the spatial interpolation method and "worm" interpolation method to determine the distribution of sedimentary micro-facies including sand ribbon and/or sand blanket. The computer software developed on the basis of the above principle provides a tool for quick visualization and understanding the distribution of sedimentary micro-facies and reservoir. Satisfied results have been achieveed by applying the technique to the Putaohua Oil Field in Songliao Basin, China.  相似文献   

陕北油气田开发中水资源综合利用   总被引：4，自引：0，他引：4  

高云文  曹海东  常铮  张荣甫  高文冰 《地球科学与环境学报》2005,27(4):75-78

通过对陕北工业用水短缺、大量污水无序排放的调查。研究了造成陕北严重缺水的原因，发现化工废水难以净化后供人们生活使用。但通过去重金属离子后可用于油田注水开发。炼油厂废水与油田产出水按不同比例混合处理后，根据不同油田储层物性进行回注采油。结果表明，处理后的污水适应于不同地质特征的产层。这即解决陕北特低渗油层注水的水敏性问题，同时也使大量污水得到充分利用，具有明显的经济效益和社会效益。  相似文献

煤矿排水对枣庄市清凉泉水源地污染作用分析          下载免费PDF全文

近年来,随着枣庄市陶枣矿区煤矿资源的大规模开发,矿坑排水对矿区地下水资源及生态环境产生的负面影响愈发突出,尤其是矿坑水沿地表河流排放途中,通过灰岩“天窗”大量灌入岩溶地下水中,造成地处煤田下游的清凉泉水源地水质遭受明显污染,供水水质难以保证。根据矿坑排水量、水源地水质、开采现状等分析认为,对串层污染进行封堵和控制矿坑水排放渠道是防治水源地污染的有效措施。  相似文献

1985年9月22日,我们用空间硬X射线望远镜HAPI-2,在我国的高空气球上,对天鹅座X-1进行了观测,望远镜几何面积为140cm~2,观测能区20—200keV,空间定向精度±0.2°。获得的硬X射线能谱陡,总辐射能流LX～1.0×1~(37)erg/sec,低于常规态。本文将介绍望远镜的性能和观测过程,能谱分析的结果,并对当时天鹅座X-1可能的“态”进行讨论。  相似文献   

Gravity-induced stresses near axisymmetric topography of small slope     

D. F. McTigue  C. C. Mei 《国际地质力学数值与分析法杂志》1987,11(3):257-268

An approximate, analytical solution is found for the gravity-induced stresses in the neighbourhood of an axisymmetric topographic feature on an elastic half-space. The solution is in the form of a perturbation expansion in powers of the characteristic slope, ?. The leading order problem, at O(1), is for a distributed normal load on a plane half-space. The O(?) correction is due to a distributed shear traction. The vertical variation of the near-surface stress perturbation and the rotation of the principal stress directions are O(?) effects, and thus include contribution s of like order from both the normal and shear loads. The method requires general solutions for axisymmetric, normal and shear tractions of arbitrary radial distribution, and these are found in terms of Hankel transforms.  相似文献
