摘要

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、技术指标达到了现场要求。

Abstract

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 , technology 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.
