Forecasting method of development index based on liquid/oil ratio in extra-high water cut stage
Online published: 2013-09-26
Aiming at the development characteristics in extra-high water cut stage, based on the research of several forecastingmethods of development index, according to the change characteristics of liquid/oil ratio in extra-high water cut stage, this paper established a forecasting model based on liquid-oil ratio, and deducted the relationship between liquid/oil ratio and water cut and the relationship between liquid/oil ratio and decline rate. The result shows that with the accumulated liquid production rising, the ascending velocity of water cut is slowdown, and when the growth rate of liquid production and liquid/oil ratio is equal, the oil production is stable. This forecasting model proves high prediction accuracy, and it is practical for oilfield development index in extra-high water cut stage.
