顶封封隔管柱的研制与应用

The Development and Application of the Upper Isolation Workstring

中原油田近年来注水压力不断升高 ,井况恶化严重 ,为此开发了顶封封隔管柱 ,主要阐述了管柱工况受力特点、结构、工作原理及现场使用效果。经现场较大面积的应用证明 ,各项性能。

The pressure of water injection is going up with the Zhongyuan Oilfield development,so the hole condition is being worse continuously.For this problem,the upper isolation has been researched.Having been applicated in larger scale,it is shown that its funtion,technolgy specification is up to the standard of the requirement on the site. The paper introduces its force characteristics,construction,working principle and on-site experimental effectiveness.
