摘要
生产气油比作为一项油田开发的重要资料,直接指导着油田地面工程的建设,由于众多历史及生产原因,目前,我们仅有部分探井的原始气油比,在油井生产过程中,当井底压力低于饱和压力后,原油中的天然气就会大量脱出,气油比则会增高,油田的开发进入中后期后生产气油比又会逐渐降低,因此原始气油比与目前的生产气油比差距较大[1],无论靠经验赋值或者乘系数估算,已不能满足油田地面工程建设需要,因此,快速、准确地测定生产气油比就显得尤为重要.
Abstract
The production gas oil ratio,as an important information for oilfield development,directly guides the construction of oilfield surface engineering.Due to numerous historical and production reasons,we currently only have the original gas oil ratio of some exploration wells.During the production process of oil wells,when the bottom hole pressure is lower than the saturation pressure,a large amount of natural gas in the crude oil will be released,and the gas oil ratio will increase.After the oilfield development enters the middle and later stages,the production gas oil ratio will gradually decrease,Therefore,there is a significant difference between the original gas oil ratio and the current production gas oil ratio[1].Regardless of relying on empirical assignment or coefficient estimation,it can no longer meet the needs of oilfield surface engineering construction.Therefore,it is particularly important to quickly and accurately measure the production gas oil ratio.
