연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An actuating apparatus for a downhole valve including a tubular body, which includes an axial bore that extends through the body. The actuating apparatus also includes an operating member that is adapted to move relative to the tubular body. The movement of the operating member relative to the tubular body is between a first position and a second position such that fluid contained within a reservoir is displaced when such a downhole valve is actuated. The actuating apparatus is adapted to be fluidly coupled to the downhole valve.

1. An actuating apparatus for operating a downhole valve; comprising: a tubular body comprising an axial bore;a fluid reservoir defined within the axial bore and fluidly coupled to the downhole valve; anda valve operating member movable relative to the tubular body between a first position and a second position to displace fluid contained within the fluid reservoir as the valve operating member moves to actuate the downhole valve, the valve operating member comprising: a hollow tubular sleeve located coaxially within the axial bore of the tubular body;a piston member coupled to the tubular sleeve, at least a portion of the piston member extending radially away from the tubular sleeve and into the fluid reservoir; anda collet-engageable coupling profile configured to be reversibly mechanically engaged with a removable downhole tool to facilitate movement of the valve operating member; anda fluid return port configured to receive a flow of fluid displaced from the downhole valve as the valve is actuated by the valve operating member. 2. The actuating apparatus as claimed in claim 1, wherein the reservoir comprises an annulus region defined between the valve operating member and the tubular body. 3. The actuating apparatus as claimed in claim 1, wherein the fluid reservoir comprises an inlet port and an outlet port. 4. The actuating apparatus as claimed in claim 3, wherein the outlet port is fluidly coupled to the downhole valve. 5. The actuating apparatus as claimed in claim 4, further comprising a conduit extending directly from the outlet port to the downhole valve. 6. The actuating apparatus as claimed in claim 5, wherein the conduit is incorporated within a downhole completion assembly. 7. The actuating apparatus as claimed in claim 1, wherein the portion of the piston member comprises an annular flange projecting radially outward from an outer surface of the tubular sleeve. 8. The actuating apparatus as claimed in claim 7, wherein the piston member is adapted to displace fluid contained in the fluid reservoir via an outlet port of the fluid reservoir to an inlet port of the downhole valve such that the downhole valve is actuated. 9. The actuating apparatus as claimed in claim 7, wherein the portion of the piston member is arranged proximate a downhole side of the fluid reservoir when the valve operating member is in the first position. 10. The actuating apparatus as claimed in claim 1, wherein movement of the valve operating member from the first position to the second position comprises an axial stroke that displaces the fluid from the fluid reservoir and simultaneously provides sufficient fluid pressure to actuate the downhole valve over at least a portion of the axial stroke. 11. The actuating apparatus as claimed in claim 10, wherein the movement of the valve operating member comprises axial movement in an uphole direction, and wherein the uphole movement of the valve operating member displaces the fluid in a generally downhole direction to actuate the downhole valve. 12. The actuating apparatus as claimed in claim 10, wherein the fluid pressure is sufficient to open the downhole valve. 13. The actuating apparatus as claimed in claim 10, wherein the fluid pressure is sufficient to close the downhole valve. 14. The actuating apparatus as claimed in claim 1, wherein the tubular body, the valve operating member and the fluid reservoir are located uphole of the downhole valve. 15. The actuating apparatus as claimed in claim 1, wherein the fluid contained within the fluid reservoir comprises hydraulic fluid. 16. The actuating apparatus as claimed in claim 1, wherein the fluid reservoir is separated from the axial bore of the tubular body. 17. A downhole completion assembly, comprising: a downhole valve; anda secondary actuating apparatus for operating the downhole valve, comprising: a tubular body comprising an axial bore; anda valve operating member comprising: a hollow tubular sleeve located coaxially within the axial bore of the tubular body; anda piston member comprising an annular flange projecting radially outward from an outer surface of the tubular sleeve;a collet-engageable coupling member configured to be reversibly mechanically engaged with a removable downhole tool to facilitate movement of the valve operating member; anda fluid reservoir comprising an annular region defined between the valve operating member and the tubular body;wherein the valve operating member is movable relative to the tubular body by an external force along an uphole axial stroke between a first position and a second position, such that fluid contained within the fluid reservoir is displaced by the piston member and conveyed in a generally downhole direction, as the valve operating member moves via the collet-engageable coupling member, with sufficient fluid pressure to actuate the downhole valve,wherein the downhole valve is located downhole of the tubular body and the valve operating member, and comprises a primary actuating apparatus operable to open and close the valve independent of movement by the valve operating member. 18. A downhole completion assembly, comprising: a downhole valve comprising a primary actuating apparatus independently operable to open and close the downhole valve; anda secondary actuating apparatus fluidly coupled to the downhole valve and configured to operate entirely independent of the primary actuating apparatus, the secondary actuating apparatus comprising: a tubular body comprising an axial bore;a valve operating member comprising a hollow tubular sleeve located coaxially within the axial bore of the tubular body;a fluid reservoir comprising an annular region defined between the valve operating member and the tubular body; anda collet-engageable coupling member configured to be reversibly mechanically engaged with a removable downhole tool to facilitate movement of the valve operating member; andwherein the valve operating member is movable relative to the tubular body between a first position and a second position to displace fluid contained within the fluid reservoir as the valve operating member moves, to actuate the downhole valve.
