摘要
油田产量预测在油田长远开发规划中起着至关重要的作用。以A rps递减曲线
及历年新井产量组成为基础, 首次建立了产量预测新模型 无因次产量组成递减率法作为
产量预测的新方法, 即以各年老井、新井无因次产量递减率分别作为老井、新井规划产量递减
率的依据, 进而达到预测老井及新井产量的目的。为验证该方法的科学合理性, 将其应用于辽
河油区某油田十一五规划中, 并与典型的常规预测方法对比分析, 得到了较为满意的结果。

Abstract
The o ilfie ld output pred iction is accom pan ied by the w ho le course o f the o ilfie ld deve lopm ent, espec ia lly play ing an essential ro le in the average and long term deve lopm ent o f o ilfie ld. Fo r th is reason, based on the A rps decreasing curv e and ou tput o f the new w ells over the years, w e have se t up the new m ode l o f rate pred iction for the first tim e d im ension less output com po sition lapse- ra te law. The law is tha t each o ld we ll and new we ll dim ensionless output lapsera te is token separa tely as the o ld w ells and the new w ells output p lan lapse-rate basis, then ach iev ing the goal o f pred icting output of the o ld w e lls and new w ells. In o rder to ve rify the sc ientific nature and feas ibility of the m ethod, w e apply it to some o il fie lds the e leventh five-year-deve lopm entp lan o f L iaohe o ilfie ld, and com pare the m ethod w ith the typical routine, then rece iv ing the comparative ly satisfactory resu lts. Th is m ethod is sim ple, practica.l And that has added am ethod fo r the output pred ic tion.
