负压解卡技术主要是利用地层流体压力与钻井液柱压力之间的压力差来解除压差卡钻 ,早已被国外应用。但是该方法技术含量高 ,风险大 ,所以国内很少采用。文中首先分析了负压解卡技术的机理、风险及使用条件 ,重点介绍了该技术在中原油田的现场应用效果。从而证明 ,负压解卡技术对压差卡钻是一种行之有效的施工方法 ,具有成本低、见效快等优点。 Negative pressure solution card technology is mainly the use of formation fluid pressure and the pressure difference between drilling fluid column to lift the pressure differential card, has long been abroad. However, the method of high technology, high risk, so seldom used in China. Firstly, the paper analyzes the mechanism, risk and conditions of negative pressure jamming technology, and focuses on the field application of this technology in Zhongyuan Oilfield. Proved that the negative pressure card technology on the differential pressure card is an effective method of construction, with low cost, quick and so on.
