Abstract
The utility model relates to a downhole tool used for open hole horizontal well fracturing in oil fields, specifically to a high temperature and high pressure resistance open hole hook wall packer, which solves the problems that a conventional packer cannot meet the requirements for hanging tail pipes and sealing large-sized casing pipes in terms of qualification. An upper cone 5 and a lower cone 14 of the high temperature and high pressure resistance open hole hook wall packer are fixed on a central pipe 1 through cut pins 6; and a piston 19 is disposed between the central pipe 1 and a piston bush 20, which is directly connected to the central pipe and is fixed by a fixing pin 3. The high temperature and high pressure resistance open hole hook wall packer is mainly applicable to fractured wells of well completion of open hole horizontal wells in the oil fields and has the advantages of simple structure, easy operation, high temperature resistance, high pressure resistance and reliable anchoring performance.
Description
Technical field: the utility model relates to a kind of downhole tool that the open-hole horizontal well pressure break is used in the oil field, belongs to a kind of high temperature high voltage resistant bore hole hanging packer.
Background technology: in bore hole pressure break completion tubular column, hanging packer will guarantee that also it is 95/8 in the whole tail pipe string of suspension " heat resisting and pressure resisting index in the large scale sleeve pipe reaches suspension tail pipe weight and sealing purpose.And common packer can not satisfy suspension tail pipe and the requirement of sealing large scale sleeve pipe aspect technical indicator.For this reason, developed and be applicable to the novel suspension open hole packer of open-hole horizontal well straight well section, this packer construction is simple; The grappling dependable performance salablely is suspended on 95/8, and " in the sleeve pipe, heat resisting and pressure resisting is high; piston bush directly links to each other with central tube, prevents that packer from setting midway.
Summary of the invention: the purpose of the utility model provides and a kind ofly in the open-hole horizontal well completion fractured well of oil field, can hang tail pipe, and the grappling dependable performance can guarantee the packer high temperature high voltage resistant again, reliable sealing high temperature high voltage resistant bore hole hanging packer simultaneously.
The utility model mainly by central tube, adjustable ring, fixing pin, upper slips, upper cone, cut off pin, go up open an umbrella, go up overall loop, go up packing element, middle packing element, inside support ring, lower rubber cylinder, overall loop, following open an umbrella down, lower cone, lower slips, lock ring, lock ring cover, piston and piston bush form; Wherein adjustable ring is set in the central tube outside, the adjustable ring lower end is equipped with upper slips, upper cone successively, go up open an umbrella, go up overall loop, go up packing element, middle packing element, lower rubber cylinder, down overall loop, following open an umbrella, lower cone and lower slips; Upper cone, lower cone are fixed on the central tube through cutting off pin, and piston is between central tube and piston bush, and piston bush directly connects on the central tube, and fixes through fixing pin.
Go up and to open an umbrella, to go up overall loop, overall loop and following material that opens an umbrella are softer metals down.Upper slips and lower slips design for cylinder-like structure, inner uniform stress groove.Lock ring adopts inside and outside toothing.
Compared with present technology the utility model has following advantage:
This tool diameter is big, high temperature high voltage resistant, and the grappling dependable performance; Have simple in structurely, easy to use simultaneously, can realize multistage packing and pressure break with tieback tube, short being used of sealing, for open-hole horizontal well fracturing integrated completion technique in oil field provides means.
Description of drawings: Fig. 1 is the utility model structure diagram.
The specific embodiment: the utility model is done further detailed description below in conjunction with accompanying drawing: the utility model mainly by central tube 1, adjustable ring 2, fixing pin 3, upper slips 4, upper cone 5, cut off pin 6, go up open an umbrella 7, go up overall loop 8, go up packing element 9, middle packing element 10, inside support ring 11, lower rubber cylinder 12, overall loop 13, following open an umbrella 14 down, lower cone 15, lower slips 16, lock ring 17, lock ring overlap 18, piston 19 and piston bush 20 are formed; Wherein adjustable ring 2 is set in central tube 1 outside, adjustable ring 2 lower ends are equipped with upper slips 4, upper cone 5 successively, go up open an umbrella 7, go up overall loop 8, go up packing element 9, middle packing element 10, lower rubber cylinder 12, down overall loop 13, following open an umbrella 14, lower cone 15 and lower slips 16; Upper cone 5, lower cone 14 are fixed on the central tube 1 through cutting off pin 6, and piston is between central tube 1 and piston bush 20, and piston bush 20 directly connects on the central tube 1, and fixing through fixing pin 3.
Go up and to open an umbrella 7, go up overall loop 8, open an umbrella 14 material of overall loop 13 and following is softer metals down.Upper slips 4 and lower slips 16 be for cylinder-like structure designs, inner uniform stress groove.Lock ring 17 adopts inside and outside toothing, and internal tooth can bear high shear force during pressure break.
During on-the-spot the use; This device is lowered into precalculated position in the well with bore hole pressure break completion tubular string; Ground adds the eyelet of hydraulic pressure through central tube 1 and acts on the piston 19, produces axially to upward pressure, and piston 19 drives between lock rings 17, lock ring cover 18 and the central tube 1 relative displacement takes place; The pin 6 of cutting off on the upper cone 5 is cut off; Upper slips 4 distending that breaks is supported on the casing wall, goes up packing element 9, middle packing element 10, lower rubber cylinder 12 distendings then, goes up and opens an umbrella 7, goes up overall loop 8 and also open thereupon and be close to internal surface of sleeve pipe; Pressure continue to increase, and the pin 6 cut off on the lower cone 15 is cut off, break distending and being supported on the casing wall of lower slips 16, and following overall loop 13, following open an umbrella and 14 also open thereupon and be close to internal surface of sleeve pipe; Stop pressurization, because the locking effect of lock ring 17, the last packing element 9 of distending, middle packing element 10, lower rubber cylinder 12 can not produce rollback, thereby accomplish setting of packer.
