Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, but not as limitation of the present invention.
What the present embodiment provided a kind of hydraulic packer send well tool, as shown in Figure 1, comprise connect successively from top to bottom top connection 1, anchor pipe nipple 3, anchor fluke 4, piston 5, transition joint 11, joint ring 12, extending connector 16, ball seat 20, lower contact 22 and ball 23.Wherein, top connection 1, anchor pipe nipple 3, transition joint 11, extending connector 16, successively with being threaded between lower contact 22, and use safetied pin locking screw, forms sealing with O RunddichtringO.
Further, top connection 1 upper end is oil pipe or drill rod thread, and inside middle has screw thread, is connected with anchor pipe nipple 3; There are the recess circumferentially staggered with packer upper end and the intermeshing boss of boss and recess in lower end circumferencial direction is staggered.
Further, anchor fluke 4 is arranged in the middle of top connection 1 and anchor pipe nipple 3, and the upper end endoporus of anchor fluke 4 has axial groove, together with being staggered installation of with the key block on anchor pipe nipple 3 cylindrical; Anchor fluke 4 lower end cylindrical is designed with special left-handed male thread, and this screw thread is connected with the internal thread of packer upper end, thus giving well tool and packer to link together.Anchor fluke 4 threaded portion in axial direction has otch, and the threaded portion of such anchor fluke 4 can inside contract when needed.
Further, piston 5 is arranged between anchor pipe nipple 3 and anchor fluke 4, is formed seal by two O RunddichtringOs 7,8 and anchor pipe nipple 3; In piston 5 upper end, by shear pin 6, piston 5 and anchor pipe nipple 3 are fixed; After shear pin 6 is cut off, piston 5 can upward sliding, finally spacing to piston 5 by the step in the middle part of anchor pipe nipple 3; Fluid enters into the sealed chamber between anchor pipe nipple 3 and piston 5 by hole sealing anchor pipe nipple 3 being close to limited step bottom.
Further, joint ring 12 is arranged on the lower end cylindrical of middle pipe nipple, is formed seal with the mandrel inwall of packer.
Further, the cylindrical of extending connector 16 bottom there is O RunddichtringO 17, formed with the mandrel inwall of packer and seal; There is liquid flow hole the middle part of extending connector 16 diametrically; Send the liquid of well tool inside by this liquid flow hole, enter into the liquid flow hole on the mandrel of packer, then enter in setting piston 5 chamber of packer.

When the present invention works, first integral-rotation, makes anchor fluke 45 and the corresponding threaded engagement of packer, makes it to link together, and joint ring 12 and O RunddichtringO 18 are formed with the mandrel internal diameter of packer and seal.Before whole tubing string enters into horizontal well, well tool is sent to bear drag load, namely the weight of all instruments sending well tool bottom is born, now, the cone step of transition joint 11 upper end, be against the lower end of anchor fluke 4, anchor fluke 4 do not thrown off with the screw thread of packer, thus send well tool to bear drag load.When tubing string enters into horizontal well or is hampered, press down tubing string, now send well tool to bear pressure loading, now, the lower surface of top connection 1 is against the upper surface of packer, thus pushes packer and move down; When needs transmitting torque, first make to send well tool to bear lower compressive load, and then rotate tubing string 1/8 and enclose, make the lower end of top connection 1 at the staggered boss of circumferencial direction and recess, intermesh at the staggered recess of circumference and boss with packer upper end, realize the function of transmitting torque.
The present invention can realize following two kinds of modes of giving up.
Mode one: after packer set, first upper lifting pipe post, makes to send well tool to bear drag load, then rotates tubing string, and the screw thread of anchor fluke 4 and the screw thread of packer are thrown off, last directly on carry and just can give up.
Mode two: after packer set, suppress from annular space (space between hanging packer top, o exterior and sleeve pipe), this pressure can act on piston 5, impel on piston 5 and move, when pressure reaches the value of setting, the power acted on piston 5 can cut off shear pin 6, thus makes piston 5 moves; The inside of such anchor fluke 4 just loses the support of piston 5, and when above carrying, the threaded portion of anchor fluke 4 inside contracts, thus throws off with packer.
It is setting that the present invention can also realize hanging packer: when occurring that fortuitous event can not carry out setting hanging packer according to normal procedure, ball 23 can be dropped into, ball falls into conical surface place, ball seat 20 top, then suppress in tubing string inside, liquid is by the liquid flow hole on extending connector 16, enter into the inside of packer, make packer set; When pressure reaches design load, it is descending that shear pin 21 cut off by ball seat 20, drops on lower contact 22 li, then makes to send well tool to give up by the above-mentioned mode of giving up, thus all can take out and send well tool.
After sending well tool all to take out, do not have legacy on hanging packer, the screw thread of packer upper end is intact and exposed, so just can descend tieback string again, carry out follow-up construction.
The invention provides several functions, and safe and reliable, a lot of problems in construction can be solved.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement or distortion, these improve or distortion also should be considered as protection scope of the present invention.
