Cement Delivery Tool.

The Omega Cement Delivery Tool is a single shot battery driven device which has been designed to deliver a large volume of cement to a downhole location on slickline.

The C.D.T. actuator is made up to a number of cement tubes. The number and diameter of these tubes is dictated by rig up height, minimum restriction and overall weight. A filling sleeve slides over the bottom of the actuator and straddles the valve sleeve which is pushed open at this time. Cement is pumped into the cement tubes via a hose which is connected to the filling sleeve. Once full, the filling sleeve is drawn down, closing the valve sleeve and locking the cement in.

The clock is programmed at surface prior to running by setting two rotary switches to select a delay time from 10 minutes to 10 hours. Threading the nosecone fully on to the tool switches power on and begins the delay countdown. Following completion of the delay, the clock powers a motor/gearhead assembly which changes the position of a valve pin. The valve pin previously isolated well pressure from a closing piston. Movement of the valve pin allows well pressure to act on this piston providing an upwards force which is transferred to the valve sleeve pushing it open. The cement is then free to drain out of the cement tubes and dump onto the top of the plug or desired location. Final traces of cement are washed from the tool as it is pulled out of the well.
