油田水地球化学的φ（logMi，L）规律及其应用

Samples of oil-field waters taken frown ten major oil-gas-bearing basins and more than fifty oil fields in China were studied on the basis of various bond parameters.It was found that the concentrations of Na^ , Ca^ 2 and Mg^ 2 (ppm)show a logarithmic correlation with the bond parameters. This correlation was treated with the quantitative formula log Mi=α bL for φ(lvg Mi, L). Additionally, the relations between the variation of φ(leg Mi, L) and the origin of oil-field waters and between that and the nature of crude oils are explored. For the convenience of solution of the formula nomography is recommended in this paper.
