液压开井阀的研制

目前,国内常用的OMNI阀(美国哈利伯顿公司)、常闭阀两种替液阀在使用过程中常会出现开关井困难、对工具要求高等问题。针对这一问题,中国石化江汉石油工程有限公司井下测试公司研制设计出了一种新型的液压开井阀。该产品结构简单、操作方便,适合高温高压工作,且动作可靠、控制精度高,现场应用中取得了理想效果。

On Development of Hydraulic Well Valve

Two frequently--used fluid replacing valves in China are OMNI valve made in HAL Haliburton Co. and normally--closed valve which are likely to bring about difficulty in on--off control of wells and higher requirements for tools during operation. A new type of hydraulic well opening valve developed by Jianghan Downhole Testing Company has advantages of easy construction and operation, heat -- pressure resistance and high control accuracy and has achieved desired result in field application.
