水平井测试技术的研究与推广

Research and Popularization of Well Test Technique in Horizontal Wells

由于水平井井深结构的特殊性,传统的监测手段无法将仪器下入水平段。为了解稠油水平井水平段动用情况,提高水平井开采效果,提出了一种水平井测试方法,通过研制一种新型单探头或多探头存储式水平井测试仪,采用随油管测试工艺,实现温压剖面测试,得到全井段的温度和压力数据。经现场应用表明,该技术简单、实用、成本低,解决了水平井温度压力监测难题。

Due to the particularity of its borehole structure pressure gauges can not be run into the horizontal interval in horizontal well.In other to find out the producing status of horizontal interval and improve development effect,a new well test method for horizontal wells is proposed,and a new type of horizontal well memory tester with either single probe or multi-probes is developed.The tester is run together with tubing,and so temperature profile and pressure profile of all intervals are obtained.Field application shows that the new technique is simple and practicable,and besides,its cost is low.
