油田投入开发以后,能否按油田逐年的实际产量预测未来的年产量及油田的最终可采储量呢?能否按油田逐年实际综合含水率预测未来的综合含水率呢?这是油田开发工作者最关心的问题,也是急需解决的问题。一、假定油田的逐年实际产量Q符合泊松旋回,并有如下关系式: Q=A+B·T~n·e~(-T) (1) T=Y-Y_0/C式中Q为拟合产量,Y_0为油田开始生产的年分,Y为投产后的采油年分,n为自然数0,1,2,……,C为拟合参数。
After the oilfield is put into development, can we predict the future annual output and the final recoverable reserves of the oilfield according to the actual output of the oilfield year by year? Can we predict the future integrated water content according to the actual comprehensive moisture content of the oilfield year by year? Most concerned about the problem, but also an urgent need to solve the problem. First, it is assumed that the actual annual oil production Q follows the Poisson cycle and has the following relation: Q = A + B · T ~ n · e ~ (-T) (1) T = Y- Y_0 / C where Q Fitting yield, Y_0 is the year the oilfield begins production, Y is the year of oil production after putting into production, n is the natural number 0,1,2, ..., and C is the fitting parameter.
