层状油气藏多层合采油气井产量劈分方法

A splitting method of oil and gas production in multiple completion wells of multi layered reservoir

层状油气藏开发过程中往往由于产量接替紧张,造成油气井生产过程中频繁的补层换层以保证油气产量的稳定,这些措施给油气藏后期潜力挖掘及方案调整带来不利影响。油气井产量劈分的方法很多,如何快速准确地确定储层砂体产出油气量,寻找剩余资源潜力,指导挖潜措施是现场人员关心的主要问题。针对现场实际情况提出了利用测井解释资料与生产动态相结合分类进行产量劈分的方法,经过现场实践证实方法简便实用,可以为现场工作人员提供借鉴。

The frequency of layer supplementing and layer exchanging is used to ensure the stable oil-gas output,since the tension of petroleum production supply during the multi layered reservoir development.This behavior led to the bad effects for later potentiality exploitation of reservoir and scheme adjustment.There are the efficient and effective methods in site practice,such as comprehensively analyzing well logging interpretation data,dynamic production data.They can provide the references for in site worker.Here,we point out the splitting method of oil and gas production in multiple completion wells of multi layered reservoir in combination with comprehensively analyzing well logging interpretation data,dynamic production data.It＇s helpful to find out residual resources and guide potentiality exploitation measure.
