Abstract: The present invention discloses a permanent packer and an extended gas lift method using the permanent packer, the method comprising: S1. imbedding the extended gas lift embedded pipe when setting the permanent packer, wherein the extended gas lift embedded pipe has an upper end being closed and a lower end being open, is provided therein with a one-way valve through which the fluid can pass from top to bottom; S2. lowering a breaking device from the production casing when in the extended gas lift, to break the upper end of the extended gas lift embedded pipe such that the upper and lower ends of the extended gas lift embedded pipe are communicated; and S3. injecting gas into the production casing, lifting the accumulated liquid in the bottom hole to the ground surface, to complete the extended gas lift.

Abstract: An exception prompting method at a communication platform having one or more processors and memory storing programs executed by the one or more processors is disclosed. The method includes configuring a user security interface; receiving a monitoring request on a target account from a user logging in to a client terminal; forwarding the monitoring request on the target account to a security platform through a service platform; receiving an exception prompt indicating an unusual activity of the target account from the security platform; generating an alarm notification of the target account based on the exception prompt; and forwarding the alarm notification of the target account to the client terminal.
