stratigraphic division

In this way, division of substrata bases on the time surface as interface which is a time-stratigraphic unit. It can avoid considering the different deposition time stratums as the same ones. 2.

利用此种方法在进行小层划分时，以等时面为界面，因此避免了将不同沉积时代的地层划分同时代地层的错误。

In this paper, the chemical data from formation water of the Y-1 well in W-depression have been systematized in order to study the hydrogeochemical characteristics and genetic types. Furthermore, the stratigraphic division and oil-gas prediction are proposed on the basis of hydrogeochemical analysis.
