| 摘 要： | 在常规有杆采油方式中，油井管柱一般采用油管和抽油杆配套，抽油杆作提升工具，油管作采油通道，作业成本高，同时油管和抽油杆的磨擦降低泵效。无油管采油技术则省略了油管投入，节省费用(单井节省材料费5—10万元)，提高了泵效(泵效提高30％左右)，取得了良好的效果。

| Abstract: | To the conventional recovery methods,the well pipe string use the matching of the oil tubing as the production channels and the sucker rods as the hoisting tool.Its operation cost is high and pump efficiency is low because of the friction between the oil tubing and the sucker rods.Through the field test,the recovery technique without oil tubing has achieved the better application results,such as economizing development cost and enhancing the pump efficieney.$$$$ |
