【摘要】：廣適水驅(qū)曲線解決了常規(guī)水驅(qū)曲線含水率及原油黏度適應(yīng)范圍較窄的問題,但目前廣適水驅(qū)曲線3個待定常數(shù)需采用試湊法求解,結(jié)果存在不確定性。文中利用廣適水驅(qū)曲線水驅(qū)動用儲量N_R與甲型水驅(qū)曲線斜率B值關(guān)系,結(jié)合歷史含水率上升規(guī)律的誤差分析,建立了廣適水驅(qū)曲線的求解新方法,該方法避免了由于系數(shù)q值的變化導(dǎo)致NR值的不穩(wěn)定性,提高了水驅(qū)曲線在產(chǎn)量及含水率上升規(guī)律預(yù)測中的精度。改進算法后的廣適曲線,可應(yīng)用于水驅(qū)油田產(chǎn)液結(jié)構(gòu)調(diào)整評價、油井措施前后水驅(qū)動用儲量評價等。
[Abstract]:The wide-range water-drive curve solves the problems of water cut and crude oil viscosity in conventional water-drive curve, but the three undetermined constants of wide-range water-drive curve need to be solved by trial-and-error method at present, and the results are uncertain. In this paper, a new method for solving the wide range water drive curve is established by using the relationship between the water drive reserve N / R and the slope B value of the water drive curve A, and combining with the error analysis of the rising law of the historical water cut, a new method for solving the wide range water drive curve is established in this paper. This method avoids the instability of NRvalue due to the change of coefficient Q, and improves the precision of water drive curve in predicting the law of yield and water cut rise. The improved algorithm can be applied to the adjustment and evaluation of fluid production structure in water-drive oilfield and the evaluation of water-driven reserves before and after oil well measures.
