摘要： The present disclosure is directed to an apparatus which can be installed for opening and closing fluid flow production from a formation penetrated by a cased well borehole and connected therewith through perforations. The production tubing string is installed with a moveable sleeve having a closed and open position. The moveable sleeve defines a controllable pathway into the production tubing string. In conjunction with that, there is an internal receptacle formed in the production tubing string to enable landing of a sonde there at. The sonde connects firmly at the receptacle. Similarly, the moveable sleeve in the production tubing string has a receptacle it in which enables unique landing of a latching mechanism, the latching mechanism extending along the axis of the production tubing string at the urging of a motor in said sonde. The motor operates an elongate extendible member to move the sleeve from the closed to the open position and back. Suitable valves, passages and containers affiliated with the sonde can be used to capture samples or to otherwise control production.
