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. 相似文献

我国陆相油田水形成的若干水文地球化学作用 总被引：3，自引：0，他引：3
Terrestrial oil-field water from the Upper Permian to Tertiary in China is charactorized by great variation in its chemical composition. According to the first three predominant ions oil-field water ean be classified into four categories, i.e., HCO2-Cl-Na, Cl-HCO3-Na, Cl-Na-Ca and Cl-SO4-Na, which are referred to as catogory A, B, C,and D for simplicity. From comparision of the features of oil-field water with those of terrestrial evaporation water, in conjunetion with available experimental results, five different hydrogeochemical mechanisms are suggested for oil-field water evolution. They are: the evaporation and concentration, the biochemical process, enrichment of trace elements, diffusion of petroleum components and various exchange processes ineluding the exchange of eations, dolomitization, isotope exchange and the reverse exchange of anions. Chemical characteristics and some regularities concerning oil-field water are interpretatod in terms of these mechanisms. 相似文献

Na^ , Ca^ and Mg^ are known to be the principal mineralizing cations in oil-field waters.Chemical controls on their activity and concentration are solubility, adsorption capacity and hydration which are dependent on the primary chemical bond parameters, such as ionic potential (Z/L)and dectronegativity (x). This paper aims at expounding the regularities governing the quantitative distribution of Na, Ca, and Mg in nil-field waters in terms of the variation of φ(Z/L, x). Our studies have shown that the log concentrations of Na, Ca and Mg in oil-field water shave a linear correlation ,vith their ionic potential and dectronegativity. Therefore, the concentrations of these cations must follow the φ(Z/L, x) regularity which has found ,vide application in the following aspects: (1) to define various types of nil-field water; (2) to define the distribution of oil-field and non-oil-field waters; and (3) to define the boundaries of hydrochemical vertical zonation. 相似文献
