An Improved Growth Curve for Predicting Development Indexes in Water Flooding Oilfield

doi:10.7657/XJPG20200218

Abstract

Abstract:

The 3Y4 growth curve is a mathematical model for predicting production and recoverable reserves of oilfields, but its prediction accuracy is relatively low and the prediction effect is relatively poor. Based on this model and the relationship between oilfield development time and cumulative production, an improved growth curve for predicting oilfield production and recoverable reserves is proposed, which covers a variety of growth curves and has certain generality. The actual application results of the improved model show that the improved growth curve has better application effect in the prediction of oilfield development index with higher prediction accuracy and better applicability and practicability, and can be used to predict oilfield production, recoverable reserves and water cut. The introduction of the improved growth curve is an effective supplementary to the existing methods for development index prediction in water flooding oilfields.

Key words: water flooding oilfield, development index, improved growth curve, oilfield production, recoverable reserves, water cut
