| 摘 要： | 针对φ101.6mm套管内径小,采用常规分层注水管柱无法开展投捞调配的问题,研制成功以配水器与封隔器一体化工具和扶正式小直径水力锚为主体的φ101.6mm井分层注水管柱。这种管柱采用绝对压力自动坐封机构,使管柱下井后直接坐井口注水即可坐封,实现分层注水。该管柱结构简单,密封可靠,有效期长,投捞测试方便,在现场应用25井次,解决了φ101.6mm套管分层注水的技术难题。 |

Separate layer water injection string for φ 101.6 mm wells |
|
| Abstract: | In order to solve the problem of lowering and pulling of the water injection string in slim hole, a separate layer water injection string for φ 101.6 mm wells is developed. It is mainly comprised of integrated water distributor and packer and small-diameter hydraulic anchor. The structure and operating principle of the string are expounded, and its application effect is analyzed. |
| Keywords: | separate layer water injection string packer water distributor |
