The Status Quo Research of Exploitation and Utilization of Underground Brine Resources in Yellow River Delta

Shallow-underground brine resources are abundant in Yellow River delta, which are mainly distributed in Wudi-Zhanhua and Dongying brine distribution area. At this stage brine resources have been maturely applied to chemical engineering industries such as salt extracting and soda manufacturing, and have acquired major economic efficiency in industry, which exerts important effects on development of Shandong economy. However, there are some problems existing in exploitation process such as single method and blindfold and out-of-order over-exploitation, therefore, shallow-underground brine cone of depression appeared. On the basis of deficient analysis status quo and drawing lessons from advanced and complex utilization pattern, we directed against the distribution and constitution characteristics of brine resources in these areas and explored model process of complex exploitation and utilization of underground brine in terms of present techniques and experience. We put forward the schemes and suggestions of geologic environment protection in exploitation process and provided new ways of thinking and scientific references for improving intra-regional environment and further exploitation and utilization of underground brine even deep layer brine all over the province.
