Technical problem to be solved in the utility model provides a kind of by reliable seal bridging plug, three groups of slips anchorings, mills the awl hydraulic pressure self-sealing self-locking the formed integrated whipstock of windowing that connects together with windowing.
The utility model comprises composite milling awl, coupling bar, connector, packing element, piston cylinder, is arranged on upper cone and lower cone in the piston cylinder, between upper/lower cone, be provided with backstay, the lower end that is characterized in described composite milling awl connects protective sleeve, between described protective sleeve and the composite milling awl rupture disk is set; Side at protective sleeve is connected with a guiding incline by dovetail groove, and fixedly connected with piston cylinder in the lower end of described guiding incline, the elongated slot of elongatedness direction is set at the back side of guiding incline; The built-in connector in the upper end of upper cone, described connector is connected with the piston cylinder weldering; Offer the endoporus that is interconnected in connector and guiding incline respectively, the outer end of the endoporus on guiding incline is communicated with described elongated slot.
The utility model solves before that seal descends bridging plug separately, descends whipstock seat envelope then, mills down to bore again and windows the problem of the loaded down with trivial details repetition of technology.Can seal by the optional position seat in down-hole casing, implement the casing window sidetracking well operations, and have the packing function.Under the situation that does not reduce operation procedure, a composite milling awl is combined with whipstock, three original road flow charts are compressed into a procedure can finish the casing window sidetracking well operations simultaneously, activity duration reduces 2～3 days than original, operating cost reduces greatly, alleviate operator's labour intensity simultaneously, shortened duty cycle, can be widely used in the operation of all size model casing sidetracking Multilateral Wells.
In addition, the utility model also also is connected with at least one auxiliary piston tube in the lower end of piston cylinder, an auxiliary lower cone identical with conical structures is set in the inner chamber of auxiliary piston tube, its inner chamber communicates with the inner chamber of lower cone, the circumference of conical face of auxiliary lower cone also is provided with auxiliary slips with matching, has on the barrel of auxiliary piston tube and the corresponding window of auxiliary slips simultaneously.Can realize three grades of more safe and reliable slips mechanisms.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model comprise external diameter less than the composite milling of oil well internal diameter awl 1, coupling bar 16, connector 18, packing element 17, piston cylinder 19, be arranged on upper cone 5 and lower cone 6 in the piston cylinder 19, between upper/ lower cone 5,6, be provided with backstay 7, backstay 7 is a hollow structure, upper cone 5 is threaded and backstay 7, and the lower end of backstay 7 is plugged in the mesopore of lower cone 6.
The epimere external surface of upper cone 5 has one section to go up the conical surface, and the hypomere external surface of lower cone 6 has one section following conical surface.The circumference of conical face of upper cone 5 is distributed with several location slips 8, and each is located on the barrel of piston cylinder 19 in slips 8 outsides and has and the corresponding window in its position, and slips 8 inboards, location are the inner conical surfaces that match with the last conical surface of upper cone 5.The circumference of conical face of lower cone 6 is distributed with several envelope slips 9, also has and the corresponding window in its position on the barrel of the piston cylinder 19 in seat envelope slips 9 outsides, and seat envelope slips 9 inboards are the inner conical surfaces that match with the following conical surface of lower cone 6.
The lower end of composite milling awl 1 connects protective sleeve 2, between protective sleeve 2 and the composite milling awl 1 rupture disk 20 is set.Side at protective sleeve 2 is connected with a guiding incline 3 by dovetail groove.The upper end welding of the lower end of guiding incline 3 and connector 4 is fixing, goes back welding piston tube 19 on connector 4, and the lower end of connector 4 is arranged in the upper cone 5.
The elongated slot 3-1 of elongatedness direction is set at the back side of guiding incline 3, offers endoporus 4-1 in connector 4, offer endoporus 3-2 in guiding incline 3, and endoporus 4-1 and endoporus 3-2 are communicated with, the outer end of endoporus 3-2 is communicated with elongated slot 3-1.
At least one auxiliary piston tube 21 also has been threaded in the lower end of piston cylinder 19, an auxiliary lower cone 11 identical with lower cone 6 structures is set in the inner chamber of auxiliary piston tube 21, its inner chamber communicates with the inner chamber of lower cone 6, the circumference of conical face of auxiliary lower cone 11 also is provided with auxiliary slips 12 with matching, has on the barrel of auxiliary piston tube 21 and auxiliary slips 12 corresponding windows simultaneously.
Load onto the stainless steel pipeline in the elongated slot 3-1 of guiding incline 3, the upper end of stainless steel pipeline is linked to each other with composite milling awl 1, the lower end links to each other with connector 4 with endoporus 4-1 by endoporus 3-2.When pressure during more than or equal to 25MPa, rupture disk 20 will explosion.Pressure then is sent in the piston cylinder 19 by the stainless steel pipeline, thereby promote upper cone 5 and lower cone 6, force and be contained in upper cone 5 and 8,9 while of the slips above the lower cone 6 spreading, pressure again with another group slips 15 spreadings, is realized anti-lost slips 8, anti-skidding slips 9 and anti-rotation slips 12 multidirectional location, unidirectional self-lock through pressure transmission bar 10 simultaneously, thereby guaranteed the reliability of slips tensioner, pressure promotes bottom piston self-locking mechanism motion simultaneously, forces packing element 17 compression-expansion, realizes packing.
After present envelope is finished, whether check seat envelope is reliable, press down tubing string 10t-20t, confirm to sit and after death to suppress again to 25MPa again, make connect the explosion of pressure transmission joint rupture disk after, pressure reduces to suddenly at 0 o'clock, the beginning circulating fluid rotates tubing string, cuts off directed pin, the beginning windowing task is realized boring for one time and is finished the whole construction operation.
Among Fig. 1,13 is that connector, 14 is valve ball for filtering aperture, 15.
