Drilling Complex Strata In Jiangxi In Wushan Copper Mine Plugging Study

The complex formation plugging Wall has been drilling engineering problem. This article is the problem of complex formation Wall plugging the basis of in-depth understanding and analysis, summed up the domestic and foreign scholars in the field of research and development and classification of complex conditions, Based on complex formation plugging in the temporal region of jiangxi province。 Put forward some new technical requirements of Wall plug drain work.In this paper, through the investigation and Study on the formation of complex mining area, thus leakage of drilling a detailed analysis, to infer ZK1as large fissures, ZK2as the fissure and karst cave,ZK3as water sensitive formation and development. Then from the theory of the hole wall instability and mechanical factors, physical and chemical factors and technical measures for engineering reasons, the formation mechanism of leakage path, leakage formation and complex stratigraphic classification, which provided the necessary theoretical basis for treatment of complex formation. On the basis of the above research in mining area complex formation treatment scheme design and discussion, firstly for leakage orientation layer through observation and geophysical prospecting method, test method and then using the experimental formula, successfully realized the application of drilling foam cement wall plugging method, liquid wall plugging method, chemical slurry wall leakage method in the project, and achieved good economic benefit. Finally, a summary of the results obtained in this study and application of supported plugging the work of. All of these provide the basic and applied research paradigm for similar work in the future.Wall plugging There are many ways, but according to the actual situation, to analyze specific issues to resolve, according to the theory, focusing on practical experience, can be a good solution to the problem of Wall plugging...
