摘要: 为了建立油田现场可操作性强的产量递减分析模型,将油藏产量按构成分为非措施老井产量、措施老井产量和新井产量三部分,建立了产量自然递减率与产量构成的关系模型,提出了自然递减率为各产量构成自然递减率的产量加权之和,引入了自然递减率贡献率概念,判断出影响油藏产量递减的主要构成;进一步将每一构成部分的产量递减率分解为现场可直接控制的液量、含油、生产井数和生产时间4个因子,依此建立了油田产量自然递减影响因素的诊断模型。根据该模型方便快捷地确定了导致产量递减的主要构成部分及其主导因素,模型计算简单,参数容易确定,有助于油田开发调整,对矿场实践具有指导意义。

Abstract: The model analyzing production decline and deciding the main factors is helpful to the development of oilfield.The reservoir production rate is composed of such parts as the production rates of measured wells,old wells and new wells.And the production decline rate is the production rate weighting sum of every part decline rate.The main part which affects the production decline rate is decided according to the contribution values of every part.Then the production decline rate of every part is grouped into four factors as liquid rate,oil cut,well-opening numbers and producing time,which can be easily controlled in the field.The diagnose model between production decline rate and the four factors is set up.According to the model the main factors which have great effect on the production decline rate can be easily decided.This research can provide criteria to take steps to slow down the production decline rate.

Key words: water flooding reservoir, production decline rate, diagnose model, production construction, affecting factors
