Abstract
The utility model relates to a multifunctional screen hanger, comprising a hydraulic system, a transmission system, a releasing tool and a packer anchoring and a packing system. The well flushing can be performed either before or after seal releasing; one-time string can complete a plurality of different operations; the immersion time of the oil layer in liquid during well drilling and other operations is reduced to reduce the oil layer pollution, simplify the working procedure and save cost; the hanger from being hung ahead is prevented to ensure the cone to move downwards to the given position and the slips to expand sufficiently is ensured so as to make the hanger hard support on the bushing and locked; the releasing pressure is designed accurately so as to avoid the excessive high or low releasing pressure due to the additional friction. The utility model has the advantages of simple structure, easy operation and field popularization.
Description
Technical field:
The utility model relates to the downhole tool that uses on a kind of oilfield, particularly a kind of multi-functional screen pipe hanger.
Background technology:
Screen pipe hanger is that sand control screen is suspended on device on the sleeve pipe, it is that the screen casing of tens of rice and even up to a hundred meters is delivered to design attitude in the well, by terrestrial operation, finishes its envelope, gives up through hydraulic pressure or mechanism, the screen casing of sending into is suspended on the sleeve pipe, thereby finishes the sand control construction.The screen pipe hanger function of the hydraulic way work of The field is fixed at present, is applicable to thin oil and common heavy oil.Coagulate oil well for super viscous crude and height,, can not be applied in the sand control construction of Expandable sand control screen because the back pressure of giving up directly releases; Because fluid cylinder seal, for super viscous crude and height coagulate oil well when sending into screen casing if oil drags the phenomenon can't high pump pressure well-flushing, movable repeatedly the increasing causes when load is transferred sand control pipe midway sealing easily, may cause the well workover accident; Because central tube can not pressure transmission be set up circulation, behind the oil well employing screen sand control for overhaul, sidetracking, only trip out and send into tubing string next time Flushing tubular column again, could replace out the mud in the pit shaft, aggravated formation contaminant; Owing to be easy to generate additional friction power when giving up, cause the descending difficulty of the sliding sleeve of giving up to be prone to give up hypertonia or lose situation about not falling.Influenced seat and hung success rate, increased working procedure, prolonged construction period, aggravated the pollution of construction liquid or mud the stratum.
Technical scheme
The utility model purpose is to provide a kind of multi-functional screen pipe hanger, and central tube can bear the interior pressure of 30MPa, and changes the pressure release mode and make pressure release in the central tube into by the original central tube side direction pressure release of passing through, and can satisfy the construction needs of expansible screen casing; Can reduce the viscosity of crude oil with hot water well-flushing or steam injection, sand control screen is lowered to smoothly; The seat that improves screen pipe hanger is hung, the success rate of giving up.
The utility model purpose be achieved in that it be by top connection (1), fluid cylinder (2), set sliding sleeve (3), set shear pin (4), lock ball (8), the sliding sleeve of giving up (19), central tube (5), the shear pin of giving up (18) constituted hydraulic system; Constituted the pressure transmission system that can bear big pressure by setting sliding sleeve (3), central tube (5), pressure tube (7), interior lower contact (17); Constituted simple and reliable releasing device by setting sliding sleeve (3), pressure tube (7), the sliding sleeve of giving up (19), lock dog (20) and the pin of giving up (18); By outer tube (10), packing element (6), cone (9), slips (11), slip spider (12), anti-seat shear pin (13), overcoat (14) lock tube (15), lock ring (16), lower contact (21) has constituted packer grappling and packing system, top connection (1) and central tube (5), interior lower contact (17) links successively, it is fixing with central tube (5) by setting shear pin (4) to set sliding sleeve (3), pressure tube (7) is fixing with central tube (5) by setting shear pin (4), the sliding sleeve (19) of giving up is fixing by shear pin of giving up (18) and interior lower contact (17), top connection (1) is outer to be fluid cylinder (2), fluid cylinder (2) successively with outer tube (10), lock tube (15), lock ring (16), overcoat (14), lower contact (21) connects, fluid cylinder (2) has lock ball (8) to be connected with central tube (5), packing element (6) is arranged on it, cone (9) is connected with outer tube (10) by setting shear pin (4), slip spider (12) is connected with overcoat (14), slips (11) is arranged on it, in central tube (5), set sliding sleeve (3), pressure tube (7), be the sliding sleeve of giving up (19) in pressure tube (7) below, anti-seat shear pin (13) connects overcoat (14) and lock tube (15), and lock ring (16) is arranged in overcoat (14), lock dog (20).
Setting ball seat is by setting shear pin location, and with the sealing of fluid cylinder inlet opening, during positive well-flushing, liquid can't enter fluid cylinder, thereby realized high positive pressure well-flushing or seat envelope midway for mud and not.Central tube and pressure tube be by the locking of lock ball, and can't produce relative displacement.When in oil pipe, dropping into a steel ball shutoff on setting ball seat, when pressurizeing from top, seat blocking seat is cut off an envelope shear pin and is moved down, drop on the pressure tube, this moment, the fluid cylinder inlet opening was opened, and the band press liquid enters fluid cylinder, and fluid cylinder is produced downward thrust, promote outer tube and lock tube and cut off anti-sit-and-sell nail, outer tube, packing element and cone together move down under the promotion of fluid cylinder, and cone is pushed slips open earlier, is stuck on the casing wall, and then compression packing element, make the glue tube base envelope, lock tube moves down and the lock ring interlock, after fluid cylinder thrust disappears, lock tube and lock ring maintain the lock status, and prevent deblocking.After the seat envelope is finished, fluid cylinder continues to move down, the cannelure of fluid cylinder just in time aligns lock ball, lock ball is headed in the cannelure under the thrust of pressure tube, the lock ball release sets sliding sleeve and pressure tube moves down simultaneously, and pressure tube promotes to give up the descending pin of giving up of cutting off of sliding sleeve, the descending back lock dog that puts in place of the sliding sleeve of giving up enters in the groove just, realizes giving up.Do not set under the situation about putting in place at packer, lock ball all the time can't be to the pressure tube release, and pressure tube can't move down, thereby prevents that the screen pipe hanger accident of giving up in advance from taking place.
The utility model is owing to adopted hydraulic system, pressure transmission system, releasing device, packer grappling and the packing system, present envelope can both well-flushing before and after giving up, and one time tubing string can be finished several different operations; Liquid has been alleviated oil layer pollution to the soak time of oil reservoir in minimizing drilling well, the operation process, simplifies working procedure, saves cost; Avoid hanger in advance seat hang, guarantee that cone is descending to put in place that slips rises fully big, makes hanger firmly be supported on the sleeve pipe and locking.Design pressure is accurate when giving up, and can not produce additional friction power and the hypertonia or can not lose phenomenon of causing giving up.The utility model is simple in structure, and is easy to use, is well suited for field popularization application.
