摘要:

为了进一步掌握油田在进入高含水阶段后的生产过程中产液量的变化特征,研究了不同开采制度下产液量
的变化规律。基于研究区块近几年的实际产油量与满足该区块的水驱特征曲线,根据油田实际生产需要,通过理论推
导,得出了高含水期定产液量下产油量的变化规律、定产油量下产液量的变化规律及产油量以不同速度递减时产液量
的变化规律,实现了产液量变化规律的定量化。以实际油田的某一生产区块为例,利用满足该区块的水驱特征曲线及
实际产量,得到了不同开采制度下产液量的变化规律。研究结果表明,搞清产油量递减时产液量的变化特征,便于油
田决策者制定切实可行的开采制度。同时,该方法也能推广到其他的高含水区块,具有非常广阔的应用前景。

Abstract:

In order to further master change law of liquid production when the oilfield enter a period of high water cut production,
we study on the change of liquid production in different production system. Based on actual oil production and water
drive curve of this block in recently years,according to actual production needs of oilfield,the change of oil production of high
water-cut stage in different producing system will be obtained by theoretical derivation when the liquid production is fixed. At
the same time,the change of liquid production is studied when the oil production is fixed or reduced at a certain speed. This
theory can realize quantification about the change of liquid production. Take a certain block in a true oilfield for example,on the
basis of water-flood characteristic curve that is suitable for this block,the change of liquid production of high water-cut stage
in different producing system will be obtained by actual data,and provide strongly theoretical guidance for decision-makers.
At the same time,this method can be used to other blocks,which has wide application prospects.

Key words: high water cut period, water-flood characteristic curve, producing system, fluid production, change rules
