摘要

油气田(藏)开发早期很难进行开发方案的设计。作者根据探明储量、最大产量、假定采收率、生产年限,提出了采用Weibull开发模型进行油气田(藏)早期开发指标预测的方法,制作了QmaxtR/No-ER图版,并根据该图版求取增长指数b,制定了Weibull开发模型的开发方案。

Abstract

It is very difficult to design an early-stage development program of an oil/gas field due to unsufficient available data.By the Weibull model,an early-stage development program was designed for predicting various parameters related to the developing process.The typical curves of QmaxtR/No vs.ER were proposed,which was convenient and practical.
