Lithofacies-based study of the structure of the aquifer system of the Cretaceous Ordos basin, China;

Relation between water level and water temperature in the aquifer system of Changli well and seismicity;

According to the hydrology geology condition,this paper discusses the principle of the division that is the absolute aquifer system and integrated water circulation.

In this paper, it is combined with the practical problems in the hydraulic system under the marine environment and our research achievement on the hydraulic system containing seawater, the key technologies are analysized of the hydraulic system containing seawater which need to solve and the system is designed, so it si of popularization and practical value.
