Abstract
The utility model discloses an emergency release suspension tool for a marine operation oil tube. The emergency release suspension tool comprises a feeding recycle connector, an upper body, a middle pressure bearing tubular column, a suspension body, a lower connector, a lower body and an O-shaped ring. The emergency release suspension tool for the marine operation oil tube is mainly characterized in that the upper part of the upper body is connected with the feeding recycle connector through threads, the middle of the upper body is sealed with the O-shaped ring, and the lower part of the upper body is connected with the middle pressure bearing tubular column through threads; the upper part of the suspension body is connected with the middle pressure bearing tubular column through threads, the lower part of the suspension body is connected with the lower connector through threads, and the middle of the suspension body is sealed with the O-shaped ring; and the lower body comprises the lower main body, anti-rotation keys, a spring, a stop block and a screw, the upper part of the lower body is connected with the lower connector through threads, the lower part of the lower body is connected with the oil tube through threads, and three anti-rotation keys are uniformly distributed on the lower main body. The emergency release suspension tool has the benefits as follows: when an emergency happens, a drilling platform can be separated from the oil tube in the lowering process; and a lowered oil tube column is suspended, and the oil tube is not required to be lifted, so that precious drilling time is saved.
Description
Technical field
The utility model relates to offshore oil equipment field, particularly a kind of operation on the sea oil pipe ejection escape hanging tool.
Background technology
Offshore oil exploitation, the degree of depth of drilling well is far longer than the depth of water, and oil pipe will be transferred to drilling well bosom contact oil reservoir, and transferring of oil pipe be to work continuously, and the time of transferring is long.Yet operation on the sea environment uncertain factor many (as abominable extreme weathers), if transfer at oil pipe emergencies such as occurring typhoon in process, relevant power tool is essential.
Summary of the invention
The purpose of this utility model is: a kind of operation on the sea oil pipe ejection escape hanging tool is provided, can be used for offshore boring island when the emergencies such as generation typhoon breaks away from the oil pipe of having transferred to the down-hole, and hang the oil pipe column firmly be lowered to, thereby needn't on carry oil pipe, save drilling time, realize operation on the sea process safety, efficient, economic.
The technical solution adopted in the utility model is: oil pipe ejection escape hanging tool comprises sends into recovery joint, top body, middle pressure-bearing tubing string, suspension body, bottom joint, lower body, O type circle.
Body top, top is threaded connection sends into the recovery joint, sends into to reclaim between joint and top body to seal by O type circle pressure-bearing tubing string in the middle of body bottom, top is threaded connection.The top body reclaims joint and is rotated counterclockwise and is upper button with sending into, and being threaded of instrument all the other positions is all the upper button that turns clockwise.
Pressure-bearing tubing string in the middle of suspension body top is threaded connection, the bottom is threaded connection the bottom joint, seals by O type circle between suspension body and production tree passage.Six holes of backflowing are distributed on suspension body.
Lower body is comprised of lower body body, anti-rotation key, spring, scotch, screw, lower body top is threaded connection the bottom joint, the bottom is threaded connection oil pipe, three anti-rotation keys are distributed on the lower body body, place spring between anti-rotation key and lower body body, scotch is fixed by screws in the lower body body, the anti-rotation key of the semicircle face contact of scotch, holddown spring.Six holes of backflowing are distributed on lower body.
The beneficial effects of the utility model are: offshore boring island is broken away from the oil pipe of transferring fast, and hang the oil pipe column that firmly has been lowered to, need not to carry oil pipe, save valuable drilling time.
Description of drawings
Fig. 1 is the sectional view of instrument, has clearly expressed the concrete structure of instrument;
Fig. 2 is the sectional view along the A-A direction, has clearly expressed the structure of three anti-rotation keys;
Figure number explanation: 1-sends into the recovery joint, 2-top body, pressure-bearing tubing string in the middle of 3-, 4-suspension body, 5-bottom joint, the anti-rotation key of 6-, 7-spring, 8 lower body, 9-O type circle, the 10-hole of backflowing, 11-scotch, 12-screw.
The specific embodiment
Further illustrate structure of the present utility model and embodiment below in conjunction with accompanying drawing.
assembling tool on rig floor, send into and reclaim joint (1) top and be threaded connection drilling rod, the bottom connects top body (2), and by O type circle (9) sealing, top body (2) is connected with middle pressure-bearing tubing string (3) by screw thread, middle pressure-bearing tubing string (3) bottom connects suspension body (4), suspension body (4) bottom connects bottom joint (5), and by O type circle (9) sealing, bottom joint (5) connects lower body (8), lower body (8) is threaded connection oil pipe, after installation, transfer drilling rod, make suspension body (4) the contact production tree passage inner seat of instrument put shoulder, transfer and put in place this moment, close the middle flashboard of preventer, make its lock live in the middle of a section of pressure-bearing tubing string (3) external diameter minimum, drilling rod four to five circles that turn clockwise make to send into and reclaim joint (1) and separate with the top body (2) of instrument, on carry drilling rod, close the preventer blank ram, then the drilling rod tubing string that is lowered to is recovered on Platform Deck, the offshore boring island displacement.After emergency finishes, the offshore boring island playback will be sent into recovery joint (1) and be connected on drilling rod, transfer drilling rod, open preventer blank ram and middle flashboard, make and send into the top body (2) that reclaims joint (1) insertion tool, be rotated counterclockwise drill string four to five circles, tight joint, in this process, anti-rotation key (6) ejects under spring (7) elastic force effect, coordinates with keyway on connector between production tree and well head head, prevents the rotation of instrument and oil pipe.Then carry drilling rod on, instrument is separated with oil pipe, the recovery instrument is proceeded the operation that oil pipe is transferred.
The above is illustrated the utility model with way of example, but the utility model is not limited to above-mentioned specific embodiment, and all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
Claims (2)
1. an operation on the sea oil pipe ejection escape hanging tool mainly reclaims joint, top body, middle pressure-bearing tubing string, suspension body, bottom joint, lower body, O type circle and forms by sending into; Wherein lower body is comprised of lower body body, anti-rotation key, spring, scotch, screw; Body top, top is threaded connection sends into the recovery joint, sends into to reclaim between joint and top body to seal by O type circle pressure-bearing tubing string in the middle of body bottom, top is threaded connection; Pressure-bearing tubing string in the middle of suspension body top is threaded connection, the bottom is threaded connection the bottom joint, seals by O type circle between suspension body and production tree passage; Lower body top is threaded connection the bottom joint, and the bottom is threaded connection oil pipe, and three anti-rotation keys are distributed on the lower body body.
