Abstract
The utility model discloses a circulation tool for casing running, which relates to a straight well, a directional well and an extended reach well in petroleum industry and exploration industry. The circulation tool for casing running is connected onto a well-completion casing string. The circulation tool for casing running comprises a pup joint (1), an anti-supporting slip (5), a rubber packer (6), a short lifting ring (7), a water hose (8) and a pup joint (9) of a three-way drill rod, wherein screw threads on the pup joint (1) are connected with screw threads on a top drive, the rubber packer (6) and the anti-supporting slip (5) are inserted into a casing, the anti-supporting slip (5) is clamped on the inner wall of the casing, and the rubber packer (6) packs the inner wall of the casing; and the short lifting ring (7) is connected with the pup joint (9) of the three-way drill rod, the pup joint (9) of the three-way drill rod is connected with the water hose (8), and the screw threads of the pup joint (9) of the three-way drill rod are connected with the screw threads of the pup joint (1). By using the circulation tool for casing running, due to adoption of the circulation tool for casing running, so that circulation at any moment in the process of casing running is formed and grouting at any moment is carried out; a sand bed at the low edge of a borehole is eliminated; the time of casing running is shortened and the labor strength is reduced; and the pressure difference for clamping the casing is reduced.
Description
Affiliated technical field
The utility model relates to oil drilling equipment, and particularly a kind of drilling completion device is used for improving the casing job speed of petroleum industry and exploration operation straight well, directional well and extended reach well.
Background technology
In the casing job of straight well, directional well and extended reach well, what continue to use for many years is with artificial mode drilling fluid charge or float shoe grouting that automatic grouting is housed in the bottom of casing string in sleeve pipe at well head always.If in the setting of casing process, be hampered, must set up circulation, remove sand setting, adopt at present to stop casing job always, well head connects kelly bar could set up circulation, influences the setting of casing time, prolongs completion period.
Utilize the top of electric drilling machine to drive the tourist bus connection circulation setting of casing device that connects circulation setting of casing device or rotary drilling abroad, can the limit when setting of casing trap tube edge drilling fluid charge or cycle operation, when setting of casing occurring and be hampered phenomenon, directly circulation setting of casing device is inserted into and sets up circulation in the sleeve pipe, circulation limit, limit setting of casing, do not influence casing job, can construct continuously, shorten the setting of casing time.
Summary of the invention
The purpose of this utility model is to provide a kind of completion system that can shorten the casing job time again easy and simple to handle.Promptly this device is connected with the TDS of casing job or is connected with the tourist bus of rotary drilling, the tourist bus of dependence TDS or rotary drilling together is inserted into anti-jack slips, rubber packer, the seeker of circulation setting of casing device in the sleeve pipe, utilize the effect of the automatic shutoff of rubber packer, trap tube edge drilling fluid charge or set up circulation of limit.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of straight well in petroleum industry and exploration industry that relates to is provided, the setting of casing circulation instrument of directional well and extended reach well, connect on the completion casing post, comprise pipe nipple (1), anti-jack slips (5), rubber packer (6), drop shot ring (7), hose (8) and threeway drill pipe nipple (9), it is characterized in that: screw thread on the pipe nipple (1) and being threaded that drive on the top, rubber packer (6), anti-jack slips (5) is inserted in the sleeve pipe, anti-jack slips (5) blocks on the internal surface of sleeve pipe, and internal surface of sleeve pipe is lived in rubber packer (6) packing; Drop shot ring (7) is connected with threeway drill pipe nipple (9), and threeway drill pipe nipple (9) is connected with hose (8), and threeway drill pipe nipple (9) screw thread is threaded with pipe nipple (1).
Circulation setting of casing device is driven on the top, the screw thread of top drill pipe nipple of this device and being threaded of TDS, rely on TDS together to be inserted into anti-jack slips, rubber packer, the target seeker of circulation setting of casing device in the sleeve pipe, it is descending to depress cylinder sleeve drive anti-jack slips at certain displacement pump, anti-jack slips plays and overcomes the piston force effect, utilize the effect of the automatic shutoff of rubber packer, the tube edge drilling fluid charge or set up circulation, the sand setting unfreezing of removing well of can the limit trapping.
Rotating disk bores circulation setting of casing device, and the drop shot ring of this device is connected with the threeway drill pipe nipple, and the screw thread of threeway drill pipe nipple (the threeway drill pipe nipple is connected with hose) drives with the top that pipe nipple is threaded in the circulation setting of casing device.Be suspended on the hook block by the drop shot ring.Rely on the hook traveling system together to be inserted into anti-jack slips, rubber packer and the target seeker of circulation setting of casing device in the sleeve pipe, it is descending to depress cylinder sleeve drive anti-jack slips at certain displacement pump, anti-jack slips plays and overcomes the piston force effect, can the limit trap tube edge drilling fluid charge or set up circulation, the sand setting unfreezing of removing well.
The utility model beneficial effect is: 1, set up circulation, grouting at any time in the setting of casing process at any time; 2, remove the casting bed on the low limit of well; 3, shorten the setting of casing time, reduce labour intensity 4, reduce pressure reduction cutting ferrule pipe
Description of drawings
Below in conjunction with accompanying drawing utility model is described further:
Fig. 1 is that circulation setting of casing apparatus structure schematic diagram is driven on the top.
(1) pipe nipple among Fig. 1, (2) back-moving spring, (3) cylinder sleeve, (4) anti-jack slips, (5) rubber packer, (6) seeker;
Fig. 2 is that rotating disk bores circulation setting of casing apparatus structure schematic diagram.(7) drop shot ring among Fig. 2, (8) hose, (9) threeway drill pipe nipple;
The specific embodiment
In Fig. 1, screw thread on the pipe nipple 1 and being threaded that drive on the top, need set up circulation time is inserted into rubber packer 6 anti-jack slips 6 in the sleeve pipe, it is descending and anti-jack slips 5 is blocked on the internal surface of sleeve pipe to utilize the circulation pressure drop to promote cylinder sleeve 4, simultaneously rubber packer 6 is lived internal surface of sleeve pipe in packing, the tube edge cycle operation of can the limit trapping.
In Fig. 2, drop shot ring 7 is connected with threeway drill pipe nipple 9, and threeway drill pipe nipple 9 is connected with hose 8, and threeway drill pipe nipple 9 screw threads and Fig. 1 drive on the top that pipe nipple (1) is threaded in the circulation setting of casing device.Drop shot ring 7 is suspended on the hook block.Need set up circulation time rubber packer 6 anti-jack slips 5 are inserted in the sleeve pipe, it is descending and anti-jack slips 5 is blocked on the internal surface of sleeve pipe to utilize the circulation pressure drop to promote cylinder sleeve 4, and rubber packer (6) is lived internal surface of sleeve pipe in packing simultaneously, the tube edge cycle operation of can the limit trapping.
