Hydrocarbon-related Hydrogeology In Bei'er Depression

Research has been conducted on hydrocarbon-related hydrogeology in Bei'er Depression, Haila'er Basin. Water-bearing rock series were classified and hydrodynamic map was drawn. Based on screening the data of formation water of Bei'er depression, the analysis between the reservoir and 30 chemical parameters of formation water in Ber'er depression has been made. From both horizontal and vertical, discusses the indicators of chemical characteristics of formation water and reservoir distribution. Study of the modern and the ancient hydro-geological characteristics in Hailar Basin and Bei'er depression has been done, and the ancient hydrogeological cycle and modern water-bearing rocks was been divided There are three hydrological plays in this block, using hydrodynamic field and hydro-chemical field determination method. Research that the origin of fomation water has been made. Formation water is mainly affected by the impact of atmospheric water, and in some aspects, it is the same as oilfield water.The relationship between different areas and hydrocarbon reservoirs has been researched. With given oilfield simulation method, 3 parameter combinations are selected, that is, organic constituent, major constituent and micro-element. On the basis of background value and critical value, 5 plays are predicted with above parameter combinations by using mutiparameters analysis, discriminant analysis and pincipal factor analysis.
