Title
(EN) METHOD AND SYSTEM FOR ESTABLISHING WELL PERFORMANCE DURING PLUG MILL-OUT OR CLEANOUT/WORKOVER OPERATIONS
(ZH) 用于在插塞研磨出或清理/修井操作期间建立井性能的方法和系统
Abstract
(EN)
A method and system is provided that analyzes flow characteristics of return fluid that flows to a surface-located facility during well operations (such as plug mill-out or cleanout/workover operations) in order to characterize local formation properties of the formation. The method and system can be used to characterize a hydraulically-fractured hydrocarbon-bearing formation that is traversed bya well having a number of intervals that are hydraulically isolated from one another by corresponding plugs.

(ZH)
一种方法和系统被提供,其分析在井操作(例如插塞研磨出或清理/修井操作)期间流到位于地面的设施的返回流体的流动特性,以便表征地层的局部地层特性。该方法和系统可用于表征由具有多个间隔的井穿过的水力压裂的含烃地层,所述间隔通过相应的插塞彼此水力地隔离。
