| 摘 要： | W11-4D-9井的地层能量低、溶解气少，传统的诱喷的方法无法实现自喷生产，而且该油由没有修井机，无法下泵生产。为充分利用该油田本身能量以及现有设备，本文提出依靠油田自’身的条件、油井现有井身结构，采取“液柱置换法”成功实现了诱喷。试验表明该方法可以连续生产，取得了很好的经济效益。

| Abstract: | For the low formation energy and solution gas, the W11-4D-9 well in Weizhou oil field can not achieve flowing production using convenctioal induced flow method. Since there is no wellmaintaining machines,pumps also can not be applied. In this paper ,a new method called Liquid Column Displacement is proposed to induce flow without using any other equipments. Experimental test were conducted, the results has shown continous production was achieves by the method presented and good economic benefits were obtained without extra investments. |
