水平井专用多功能套管鞋的研制与应用
|
摘要
为了提高水平井固井质量,针对水平井固井中存在的套管下入困难、管外顶替效率差、管内断流不彻底等难题,研制出了水平井专用多功能套管鞋。该工具由三大模块构成,其中自旋转下套管模块利用偏心旋转头在受力不均下可以自由旋转的原理引导套管柱顺利下入,旋流振动固井模块利用压力波周期变化产生振动波的原理来提高水平段的顶替效率,而碰压关井模块则是利用滑套原理来现实碰压后套管的硬关井。因此,该工具有益于水平井固井前套管串的下入、固井中环空注替效率的提高以及固井后套管关井的可靠。现场应用表明,该工具结构合理、性能可靠,对提高水平井固井质量有显著效果。
To improve cementing in horizontal wells,a special multi-function casing shous was developed to overcome the problems of hard casing running,poor displacement outside casing,and not effective flowing stop inside the casing. It consists of 3 modules. The self-rotating casing running module is to rotate itself to guide the casing string down into the hole,the vortex vibration cementing module is to generate vibration wave to improve the displacement in the horizontal section,and the pressure-bump shut-in module is to adopt the sliding sleeve principle to perform hard shut-in in casing after pressure bumping.So this tool will facilitate casing running,cement displacement in annulus and hard shut-in after pressure bumping. Its field application shows the tool has reasonable structure and reliable performance,acting extremely well in improving the cementing quality in horizontal wells.
