套管抽汲配套工具的研制与应用

井筒抽汲捞油是各油田低产低能井普遍采用的一种采油方式,根据这种采油方式的需求,开发研 制了配套井筒抽汲工具。井口采用远程液压防喷盒,实现了多级远程液压防喷密封手动控制系统,工艺 技术性能稳定。安装简便快捷,井口密封效果好,无污染;井口安全脱节的密封系统实现了顶钻时的安 全脱节作用;井下抽汲胶碗的设计具有生产快捷,投入少、成本低、更换简便等优点,在克拉玛依油田 取得良好的应用效果。

Development and Application of the Casing Swabbing Corollary Tool

Oil swabbing and bailing are used as an oil production method for oil wells with low production. According to the needs of this oil production method, corollary wellbore swabbing tools are developed. By applying the remote hydraulic blowout preventer in the wellhead, manual multi-stage control, remote hydraulic blowout prevention comes into true. This technology has stable performance, and it can be installed simply. It has good leak-proof seal without pollution. The wellhead seal system can throw off safely against abnormal high pressure. The design of the down-hole swab rubber has many advantages, such as wide material resources, easy manufacturing, low investment, low cost, handy replacement. The new weight rod can solve weighting, partial wearing, centralizing problems. Good results are obtained by the using the tools for casing swabbing in Karamay Oilfield.
