A hydraulic piston is located inside the hydraulic piston chamber. A kickover arm portion is mechanically connected to the hydraulic piston, the kickover arm portion comprising a kickover arm having a tool portion. The kickover arm has a non-kicked-over position where the kickover arm is substantially coaxial with the longitudinal direction and a kicked-over position where the kickover arm is substantially non-coaxial with the longitudinal direction. The kickover arm moves to the kicked-over position upon extension of the hydraulic piston.
TECHNICAL FIELD The present application generally relates to tools (e.g., kickover tools) for placement and removal of valves from side pocket mandrels.
BACKGROUND The present application relates to valves such as waterflood/Injection valves, gas lift valves (IPO Injection pressure operated and PPO Production pressure operated), chemical injection valves, shear orifice valves, orifice valves and dummy valves.
SUMMARY A non-limiting embodiment of the invention includes a tool for inserting and removing a valve in a downhole mandrel. A body extends in a longitudinal direction and has a first end and a second end. A hydraulic chamber is within the body and extends from the first end. The first end and the hydraulic chamber are hydraulically connectable to coiled tubing. A piston chamber is inside the body, the piston chamber extending from a second end of the body and being hydraulically connected to the pressure chamber. A piston is slidably located within the piston chamber. An actuation device is connected to the piston. The actuation device comprises a first actuation part having a first position and a second position. A second actuation part has a first position with reference to the first actuation part and a second position with reference to the first actuation part. The piston mechanically connects with the second actuation part. The first actuation part is connected with the piston by way of the second actuation part. Upon actuation and movement of the piston with respect to the first actuation part, the second actuation part moves with respect to the first actuation part thereby placing the second actuation part in the second position. The actuator device is mechanically connected to a kickover arm device. The kickover arm device has a non-kicked-over position and a kicked-over position. When the second actuation part is in the first position, the kickover arm device is prevented from moving from the non-kicked-over position to the kicked-over position, and when the second actuation part is in the second position, the kickover arm tool is allowed to move from the non-kicked-over position into the kicked-over position.
BRIEF DESCRIPTION OF THE FIGURES FIG. 1 shows a portion of a kickover tool.
DETAILED DESCRIPTION In the following description, numerous details are set forth to provide an understanding of the present invention. However, one skilled in the art will understand that the present invention may be practiced without these details and that numerous variations or modifications from the described embodiments are possible.
FIG. 3 shows a fifth part 5 that is connected with the fourth part 4. The fifth part 5 includes an extension 43 of the pressure chamber 10. The fifth part 5 and the fourth part 4 can be a unitary part or multiple parts. Further, the fifth part 5 includes a hydraulic piston chamber 10 b. A hydraulic piston 50 is located inside the hydraulic piston chamber 10 b. A first end of the piston 50 a is hydraulically connected to the extension 43. As hydraulic pressure increases in the extension 43 pressure is transferred to the end 50 a of the piston 50. The piston 50 moves within the piston chamber 10 b. FIG. 4 shows a portion of the kickover tool 100 that is to the right of the portion shown in FIG. 3. The piston 50 extends within the piston chamber 10 b. A downhole side 10 c of the piston chamber is shown. The piston chamber 10 b is hydraulically connected to outside the kickover tool 100 by way of passageways 54. The fifth part 5 connects with a sixth part 6. The fifth part 5 and the sixth part 6 could be a single unitary part or multiple parts. An orientation key 60 is connected to the surface of the sixth part 6. The orientation key 60 comprises a protruding portion that extends beyond a surface of the sixth part 6. The orientation key 60 can be movable in/out in the radial direction and can be biased by springs 62 in the radial direction. Bolts 61 can be used to secure the orientation key 60. In operation, as the kickover tool 100 is lowered downhole and in proximity to a mandrel, orienting sleeves (FIG. 7) are encountered. The orienting sleeves are angled and contact the orientation key 60 thereby rotating the kickover tool 100 to a proper angle. A downhole direction orienting sleeve can be used, and an uphole orientating sleeve can be used. As the orienting key 60 passes through the downhole orienting sleeve in the downhole direction the kickover tool 100 is rotated. Also, as the orienting key 60 travels through the orienting sleeve in the uphole direction, the kickover tool 100 rotates. That aspect is beneficial because when lowering in the downhole direction, there is potential for the orienting key 60 to contact a �point� of the orienting sleeve and to not achieve rotation. Thus, by lowering the kickover tool 100 and then raising the kickover tool 100 within a mandrel, any chances of the kickover tool 100 being improperly oriented are greatly reduced.
