摘要(Abstract):
喇萨杏油田属于多结构开发油田,在研究含水、递减率、储采比、剩余可采储量采油速度等开发指标变化规律时,应考虑不同开发单元指标变化对总指标的影响,即用结构分析方法进行研究。为此,运用油藏工程原理和系统工程方法建立了多结构条件下的含水率、产量递减率、储采比、剩余可采储量采油速度等开发指标的计算公式,并对油田实际开发指标变化规律进行了分析。研究表明,每个开发指标本身也是一个系统,其变化规律受该指标各组成部分的影响,必须运用结构分析的方法研究每个结构指标的变化规律及每个结构指标对该指标的影响,才能真正的搞清油田开发指标的变化规律,为油田开发决策提供科学的依据。
Lasaxing Oilfield attributes to various structural development oilfield,thus study on several development indexes variation rules,including water cut,declining rate,reserve/production ratio,remaining recoverable reserves and production ratio,the effects of various development index variation on the whole index are considered,in other words,which is structure analysis method study.So,application of reservoir engineering theory and system engineering method establish calculation formulas for several development indexes under multi-structure condition,including above those.The study indicates that,each of development indexes is also a system by itself,its variation rules is influenced by different composition parts of this index,thus each of structural indexes variation rules and the effects of every index on this index are studied by using structure analysis method,which can truly understand variation rules of oilfield development indexes and provide scientific basis for development decision.
