Wetting agent investigation for controlling dust of lead-zinc ores

The purpose of this project is to control the pollution of dust,which occurred in a typical lead-zinc mine.Two kinds of surfactants and water glass were chosen as the wetting agents to study the behaviours of suppressing the dust.The performances of the wetting agents of various sizes and water content of dust and their compositions among different weting agents were investigated. Firstly,the chemical compounds,dispersity,water content,bulk density and other relevant physico-chemical properties of the choiced dust of lead-zinc ore were mensurated.A great number of down-ward penetrating tests were conducted to different partical sizes of dust and to analyze the dust wetting behaviour respectively.The optimal compositions of wetting agents were obtained in accordance with different water contents and partical sizes of the dust after analyzing and statisting the achieved experimental data. The data show that the efficiency of chemical dust suppression of weting agents is much better than that of water.The results of the research work prove that the partical size and the water content of the dust are very important factors to the dust suppression.The results are also proved validly by the dropping experiment,which takes the penetrating diameter and penetrating time as the major factors.The superfine dust is much more difficult to be wetted.Since increasing the water content of dust is the best approach to control it,the choice of wetting agents for improving dispensation is significant.     

渗流计算中的一维压缩存储及PCG程序设计

在大型渗流计算中,由于总导水矩阵的对称性、大型性、稀疏性,导水矩阵数据的存储算法对总导水矩阵的存储量起关键作用。结合PCG方法探讨了矩阵的一维压缩存储算法,提出了本算法的计算理论和方法。实例计算结果表明,一维压缩存储PCG求解能够显著减少计算时间、降低计算成本。     

七个泉油田储层认识及测井多井解释

由于七个泉油田沉积环境复杂,多变,造成岩性复杂,多变,给测井资料的解释带来困难,储层难以识别,储层类型复杂。通过测井与岩芯的结合,对七个泉油田不同地层岩电关系进行了研究,确定了七个泉地区的储层电性特征,解决了长期困挠的储层识别的问题,为高效合理开发油田提供了科学依据。     

改性脲醛胶的研制

利用加入三聚氰胺，聚乙烯醇等改性剂来改善脲醛胶的耐水性和耐老化性，同时降低游离醛的含量，在使用时加以改性填料，可提高脲醛胶的剪切强度，并降低脲胶醛胶的成本。
