Abstract

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
