1) super-long cement plug
超长水泥塞
2) cement plug
水泥塞
1.
Tech of setting cement plug by infilling Cement is to send tube, cement filling sleeve and its tools to the predictive depth by swabbing rope.
倒灰法打水泥塞工艺是利用抽汲绳将油管或专用装灰筒及倒灰工具下到预定深度,在1m范围内上提下放数次,使倒灰孔打开,实现水泥浆从油管流入井筒,同时胶塞从护套中推入套管实现地层封堵。
2.
In the process of cementing plug, cement plug length can't control and easy to make accident, for example “fill the sausage” and “insert the flagpole”.
针对常规打水泥塞作业经常出现不易控制长度、水泥塞容易“打飞”、易出现“灌香肠”、“插旗杆”等实际问题,通过对水泥塞固井技术的研究,开发出一种新型工具—水泥塞定位器。
3.
Combina-tion of drillable tubing conveyed bridge plug with cement plug is proposed for use in this oilfield.
提出用可钻式油管传输桥塞与水泥塞结合封堵下部高压高含水层,经3口井的现场应用表明,该工艺投资少,现场操作简单,封堵成功率高,可靠性强,且有效期长,增油降水效果显著,解决了该油田生产中下部高压高含水层的封堵难题。
3) cementing plug
打水泥塞
1.
