采用液面推算静压的方法及认识

THE METHOD OF CALCULATION THE STATIC PRESSURE BY USING THE LIQUID LEVEL

随着胜坨油田特高含水期开采难度的增大 ,各种动态监测技术的综合运用显得尤为重要 ,油井压力的录取是油田开发重要的动态监测手段 ,压力资料是确定单元合理注采比 ,制定单元注采调整方案的重要依据 ,在分析传统的推算静压方法的基础上提出不停井用动液面计算静压的方法 ,从而减少产量损失 ,全面及时掌握地层压力变化状况 。

Along with the difficulty of mining in Shengtuo Oilfiled increasing in high water-cut period,the integration application of kinds of dynamic Monitoring technology is very important.Gathering the pressure of the oil well is a dynamic Monitoring means of the oil field exploitation.The pressure data is an important base for determining rational injection-production ration and establishing injection-production adjusted scheme.On the basis of analyzing the traditional calculation method of static pressure,this article put forward the method to calculate the static pressure by using producing fluid level.As a result,it can reduce the loss of output and completely master the changing of the formation pressure in time ,and it is beneficial the exploitation of the reservoir.
